How to solve this phenomenon when there are bubbles in TPE elastomer injection products?
How to solve this phenomenon when there are bubbles in TPE elastomer injection products?
[Question] We use TPE material, how to adjust the machine if the injection product has bubbles? How to solve?   【Answer】Cause analysis and countermeasures:   1, the sol temperature is too high to cause too much volatile matter, reduce the temperature of the barrel. If the barrel temperature is too high or the heating is out of adjustment, the barrel temperature should be reduced step by step. The temperature in the feeding section is too high, because part of the plastic melts prematurely and fills the groove with air and cannot be discharged from the feeding port.   2, the injection pressure is small, the pressure holding time is short, and the melt does not adhere to the surface of the cavity.   3, the injection speed is too fast, the molten plastic is decomposed by the large shearing action, and the decomposition gas is produced. The injection speed is too slow to fill the cavity in time, resulting in insufficient surface density of the product to produce silver streaks. Increase or decrease the injection speed.   4, the sol temperature is too low to make the filling unstable, the internal stress increases, and the material temperature and nozzle temperature are correspondingly increased. Insufficient amount of material, excessively large feeding cushion, too low material temperature or too low mold temperature will affect the flow and molding pressure of the melt, and generate bubbles.   5, use multi-stage injection to reduce the silver streak; medium-speed injection fills the runner, slow-speed fills the gate, fast injection, low-pressure and slow-speed injection to fill the mold, so that the gas in the mold can be removed in time in each section.   6, the rubber stays in the barrel for too long, so the total cycle time needs to be reduced.   7, drying of raw materials. Fully dry raw materials to reduce residual moisture.

Application of TPE elastomer raw materials in plastic runways, floors and mats
Application of TPE elastomer raw materials in plastic runways, floors and mats
Due to the softness and excellent elasticity and toughness of TPE itself, more and more applications have been used in floor paving materials in recent years. As an environmentally friendly non-toxic product, TPE has the high elasticity of rubber. In terms of environmental protection indicators, they are better than other raw materials. TPE has the advantages of light weight (low density), environmental protection (recyclable, non-toxic in combustion), long service life (up to 5-10 times more than traditional rubber), large processing variation, and low total product cost. It is used in various industries. Has gradually been widely used.    One, home textile carpets, floor mats, non-slip mats    Home textile carpet mats are generally laid on the door, living room, bedroom, bathroom and other indoor and outdoor floors and floors, which play a role in sound insulation, decoration, anti-slip, and improve foot feel. With the family living environment and quality of life    improvement, more and more families are choosing to lay carpet and floor mats.    home textile carpets are usually covered with a layer of rubber bottom to improve the carpet's adhesion to the floor and anti-slip effect, especially for ceramic tiles and floors. Traditional non-slip soles generally use PVC, traditional rubber or latex, with environmental protection   The requirements are increasing. These materials are gradually eliminated. TPE for home textiles and carpets has excellent performance. It can not only completely replace PVC, traditional rubber and latex to achieve the bottom-covering and anti-skid effect, but also greatly simplify and shorten   The production process is environmentally friendly, non-toxic and tasteless, and it is an environmentally friendly new material, which has been widely used in the home textile carpet industry.    2. Car carpets, floor mats    In China, TPE has been used in automotive carpets for nearly 10 years, and it has basically matured. As the automotive industry has higher and higher requirements for VOCs, TPEs for automotive carpets are also constantly upgrading. At present, TPE is in the automotive industry. The    car carpet is in addition to the traditional nylon carpet covered by the original factory standard. The new design includes integral injection molding foot pads and blister foot pads, as well as blister trunk pads and so on. In addition to VOC requirements, the safety of materials    properties, flame retardancy, and low temperature warpage resistance have all raised requirements.    3. Plastic track, floor   1, floating floor    In the past two years, the fermentation of the poisonous runway incident has sharply accelerated the paving and use of suspended floors. According to Internet reports, kindergarten suspended assembled floors occupies about half of the country. Because of its convenient installation, environmental protection and non-toxic   , healthy and comfortable, excellent sports, durable, it is popular in kindergartens, sports venues and other fields.   2, plastic track    Although the floating floor has many characteristics, its elasticity, foot feel, shock absorption and cushioning effect, easy to fall, etc. still cannot be compared with rubber particles. The new thermoplastic elastomer rubber particles are not only in shape and traditional Similar to the track particles, the pavement molding process and equipment are also the same as the traditional rubber track particles. Its environmental protection and low odor characteristics are better than the traditional rubber particles and the current EPDM rubber particles, and it improves the elasticity and cushioning of the existing suspended floors.

TPE and TPR materials have become the preferred raw materials for rubber-coated kitchenware handles
TPE and TPR materials have become the preferred raw materials for rubber-coated kitchenware handles
Kitchenware handles are the part where kitchen workers touch the kitchenware. The materials of the handles are different, and the gripping comfort experience is also different. As people's pursuit of life taste is getting higher and higher, the requirements for kitchenware products are becoming more and more "picky".    Many kitchenware products are currently exported abroad. The most common kitchenware body is metal, with wooden or plastic (such as bakelite, nylon, ABS, PP, etc.) handles embedded on the metal. Plastic is a poor conductor of heat, which prevents human hands from being burned. Most of the handles are made of a three-composite material of metal + hard plastic + soft rubber. The newly introduced soft rubbers are usually mainly TPE and TPR, while silicone rubber is also a small part. TPE and TPR materials are added to the kitchenware handles-this type of design uses the softness and anti-slip properties of TPE/TPR thermoplastic rubber materials to provide a soft touch and anti-slip property for the product to be held, and the use experience is better and improved Product added value. Usually the hard plastic (such as ABS, PP, nylon PA, etc.) handles are first fitted with metal kitchenware parts (some kitchenware uses hard plastic parts directly without metal materials), and then two-shot injection molding (or two-color injection molding) is used. TPE, TPR soft material is injection-molded onto the hard plastic handle. This two-color material kitchenware handle not only gives a good gripping body feel, but also increases the aesthetics of the product, and improves the taste of the kitchen and home furnishings.

[Case Sharing] New TPE Outdoor Sports Glove Material
[Case Sharing] New TPE Outdoor Sports Glove Material
Gloves are used for hand warming or labor protection, and they are also used for decoration. Gloves are a very special thing. At the beginning, they were not produced for practical use. Only in modern times have they become necessary for heat preservation in cold areas, or medical antibacterial and industrial protective products.    According to medical information, two-thirds of the sweat glands of the human body are distributed in the palm of the hand. This shows that the hand is the most sweaty part of the human body. In outdoor sports, activities such as crossing forests, climbing in the wild, skiing, etc. all require holding trekking poles, climbing from forests, rocks and sliding ski poles. The palm becomes very slippery, which reduces the holding ability of the palm, which will directly affect the safety of outdoor activities.   The new type of climbing gloves, using TPE as the surface layer, bonding cotton fiber, soft touch, anti-skid, protective effect, through the technical research of the engineering department, cooperated with customers, successfully realized mass production and sold overseas! Customers supply related gloves, traditional cotton and linen gloves, and leather gloves for foreign sports products, but none of them can meet market demand. TPE elastomer materials, as new environmentally friendly materials, are widely used in various industries. Therefore, customers find us and hope that we can provide material solutions. .   Customer requirements are as follows:    Weather resistance, high temperature resistance 60℃*168h    Moldability Injection molding    Is it possible to encapsulate the cotton fiber   Other characteristics The surface is matte and dry    Disc vertical injection molding machine, rubberized cotton fiber,    requires the material to feel soft and dry, and the matte surface is wear-resistant. The disc abrasion test is more than 1000 revolutions. The molding temperature is 190-200℃.    Preliminary engineering analysis shows that this kind of hand feel requires very soft materials, so first try the natural material TSN1539D-W, the glue point is easy to delaminate. After the sample came back, the internal analysis of the project found that the original color was not suitable, and a translucent material, ES0803F, was recommended again. The surface was too bright and the molding was OK. This is not the same as the customer's surface requirements for the dumb surface, NG. The engineering department proposed an improvement plan. Based on the ES0803F, the formula was optimized, the surface haze was improved, and the sample material ES15-LB was made, and it was brought to the customer as soon as possible. After testing on the spot, after debugging, the final product reached the customer's requirements and went smoothly. Place an order, mass production and shipment.

How to choose the right hardness when designing TPE products?
How to choose the right hardness when designing TPE products?
TPE is used for encapsulation and shooting, and TPE soft rubber is used as the soft rubber outer coating. The common hard materials that match are mainly plastics, but also metals and woven fabrics. TPE and woven fabric shot bonding are mainly used in luggage products. Like metal encapsulation, they are generally fake encapsulation. Real encapsulation is more common in two-shot injection molding and two-color injection molding, that is, the main material of TPE encapsulation is plastic. TPE can be firmly bonded to some commonly used general plastics PP, GPPS, HIPS, ABS and engineering plastics PC, PC/ABS, PA and their modified materials.   How to choose the hardness of TPE encapsulation? The hardness of TPE encapsulation and TPR encapsulation varies with the different substrates of the encapsulation and the requirements of physical properties. If it is PP package (TPE package PP, TPE package PP, TPR package PP), TPE, TPR is about 30-60A, while plastic polycarbonate (PC), nylon (PA6), ABS , The hardness will be higher. It also depends on the purpose of use. For example, the encapsulation of children's toothbrushes is relatively soft, bicycle grips, pen holders, golf club grips, and sports equipment grips are slightly taller, and screwdrivers with stronger force have relatively hard encapsulation, and Some metal-clad and rubber-coated stainless steel have a hardness of about 80A. At the same time, men exert more force than women, and adults are stronger than children, so the hardness is greater;    The hardness of TPE is defined as the dent resistance of the material when a static load is applied. Hardness is also related to other important physical properties, such as tensile modulus and flexural modulus. Due to the various measurement scales and hardness, as well as the relationship with other material properties, confusion may arise when discussing hardness. When choosing a thermoplastic elastomer (TPE), the hardness of the material is often one of the first indicators that need to be considered. Thermoplastic elastomer (TPE) can produce standard products with hardness from Shore A0 (the softest) to Shore A95 (the hardest).    TPE encapsulated elastomer soft rubber can be adjusted to the appropriate hardness (hardness range Shore 25-90A) and appropriate physical properties (such as abrasion and scratch resistance, adhesion, melt index, etc.) according to the physical requirements of the product. Provides a variety of possible material application solutions for different products.

 Principle analysis of TPE, TPR adhesion (self-adhesive and co-adhesive)
Principle analysis of TPE, TPR adhesion (self-adhesive and co-adhesive)
Conventional TPE and TPR do not have functional viscosity, but need to adjust the compounding system to obtain the required adhesion (adhesion). With the continuous deepening and expansion of the application of thermoplastic elastomers TPE and TPR, the adhesive properties of TPE and TPR (including self-adhesive and co-adhesive) may gradually be applied in different industries.    Regarding the viscosity of TPE materials, here are three different meanings of viscosity:    1. Self-adhesiveness of TPE material; refers to the strong adhesion of the surface of TPE material, similar to the surface coated with glue. This kind of TPE material with strong self-adhesiveness can be used to paste daily necessities to prevent it from falling or tipping over when touched. Similar TPE materials, a foreign TPE manufacturer has specialized research and development, and applied for a patent. In fact, in the conventional TPE compounding system, adding a tackifier with good compatibility with the main compounding system can improve the viscosity of the TPE material surface. This kind of stickiness is positive and is what users demand and hope.    2. Adhesiveness on the surface of soft TPE material. Some low-hardness TPE materials have a sticky feel on the surface of the soft TPE material due to the high content of oil components in the compound. This sticky feeling is caused by the oil in the formula. Generally, TPE (TPR) based on SBS is more prone to surface stickiness. This kind of stickiness is negative and is what users want to eliminate.    3. Viscosity problem during overmolding. The stickiness mentioned here refers to the fusion bonding between the TPE and the coated substrate (plastic) due to the close solubility sp or good compatibility when injection molding at high temperature. effect. The quality of the adhesion is mainly determined by the surface affinity of the TPE and the coated plastic (similar melting point, close polarity and surface tension, etc.)    The co-stickiness of TPE and TPR is numerous in application. Most plastics, a few non-metallic materials and metals can be bonded to TPE and TPR in a manner similar to co-bonding.    (1) Co-bonding of TPE, TPR and plastic    This is the most common co-adhesion. The co-bonding of TPE, TPR and plastic has a more familiar name in the industry-overmolding, also known as overmolding, overmolding, two-color/multi-color injection and so on. The encapsulation applications of TPE and TPR can be seen everywhere in daily life. The co-bonding effect of TPE, TPR and plastic depends on the difference in polarity between the two materials and the surface tension of the plastic. At present, the industry can provide mature technology TPE, TPR products, and most plastics such as ABS, PA, PC, PP, PS, PCTG, PBT and other good mutual adhesion (encapsulation).    (2) Co-bonding of TPR, TPE and metal and other materials    The co-adhesion of TPR and metal, this term is not so justified. Because TPE, TPR and metal bonding encapsulation, in most cases, not relying on the real bonding effect of the material, but using some special metal parts structure, or through the structural treatment of metal parts, through insert injection molding , The way of buckle coating, through physical and mechanical fixation, realizes the composite encapsulation of the two materials, rather than the literal co-adhesion. However, it is said that a small number of metal materials with higher surface chemical activity and TPE materials that have been polarized by functional groups can also be combined with materials under higher temperature conditions. This combination has a certain degree of firmness and does not rely solely on mechanical The embedding method has some co-adhesion effects.
