TPE/TPR is a soft rubber material and its anti-slip performance is introduced

TPE/TPR is a soft rubber material, and TPE/TPR performance of similar related materials are EVA/POE, PVC, silicone, TPU/TPV, (vulcanized) rubber, etc.. 　　EVA/POE, belongs to a class of polyolefin elastomer TPO. Although this type of elastomer has a soft touch, but because the molecular monomer unit is a single direct olefin polymerization structure, does not contain benzene ring, the material's anti-slip performance is lacking, anti-slip and wear strength is poor. For soft rubber products injection molding applications are limited, generally some craft jewelry, small toy products, and toughening modification. 　　2. PVC soft rubber. Although PVC has good elasticity, but the lack of rubber texture, anti-slip performance in general. In addition, the environmental performance of PVC also affects its application space. 　　3. Silicone. The molecular chain structure of silicone only gives it a good amount of resilience, aging and weathering resistance, and excellent environmental characteristics. Silicone shell with excellent soft touch, but in the anti-slip performance, silicone is not good. 　　TPU/TPV. These are two common types of thermoplastic elastomers. Both materials have some rubber anti-slip properties. But these two materials in the soft touch is poor. 　　5. (Vulcanized) rubber. This material has excellent wear resistance and anti-slip properties, vulcanized rubber system has excellent heat and chemical resistance and physical and mechanical properties, making its application focused on industry, automotive tires, industrial conveyor belt industry is one of its most important applications. 　　6. TPE/TPR elastomer. This refers to the SEBS, SBS polystyrene type of elastomer alloy. This type of material has a rigid molecular structure of styrene and flexible butadiene (or butene-ethylene) molecular chain structure, making TPE/TPR has a certain strength and excellent flexibility of touch at the same time. 　　The strength, abrasion resistance and anti-slip properties of TPE/TPR are not as good as those of vulcanized rubber, which makes its application fields for some daily-use products, tools and hardware, and electronic products. The following are some application cases of TPE and TPR products with anti-slip properties. 　　6.1 Handlebar category. Tool hardware, bicycle and motorcycle handle, luggage handle, knife and kitchenware handle 　　6.2 Anti-slip mats. Such as car with non-slip foot pad, car interior accessories non-slip pad, cell phone non-slip pad, (material surface with strong adhesion), bathroom|bathroom non-slip pad, water cup coaster (compound injection or single material molding), non-slip bowl mat, etc.. 　　6.3 Shoe soles: TPR soles have excellent anti-slip properties, and compared with rubber, the taste is much smaller, and the soles feel more soft and comfortable. 　　6.4 Various (industrial, stroller) casters. Caster industry, TPE/TPR and TPU are used. But TPR has a softer non-slip characteristics, can be used in the production of medical industry with silent casters, TPU material caster, friction sound is relatively large. 　　The special anti-slip characteristics of TPE/TPR provide more possibilities for people's work and life, and the adjustable characteristics of its hardness and physical properties provide a wide range of imagination and design space for product designers. Its environmentally friendly and non-toxic characteristics give consumers complete peace of mind. Thermoplastic elastomer TPE, TPR, committed to creating a better and more comfortable life!

Waste SBS soles can be recycled and reused, and the cost is moderate. The sole style can be translucent cowrie sole or brightly colored two-color sole, and can also be made into a foam sole. These excellent properties of SBS make it very widely used in the shoe industry. China is the world's largest footwear producer and the largest consumer market for footwear products, and the footwear market will remain the main target market for domestic SBS for quite some time to come. After China's accession to WTO, the export quota for footwear will be abolished and the export advantages will be more fully exploited. In order to eliminate the imbalance between the development of the eastern and western regions, the country has started to increase its investment in the western region to accelerate its economic development. In the coming years, as the western economy takes off and people's living standards increasingly improve, the demand for shoes made of TPR (SBS shoe granules) will rise year by year. In addition, the opening up of the western economy to the outside world will attract the footwear industry to move and develop in the west, thus driving the demand for SBS in the whole western market. 2003 in the footwear industry, China's SBS consumption was about 213,000 tons, and is expected to reach 247,000 tons by 2008, with an average annual growth rate of about 3% from 2003 to 2008. 　　Thermoplastic elastomer TPR / TPE in the application of asphalt modification: SBS in the application of asphalt modification, including waterproofing membrane asphalt modification and road asphalt modification in two areas.

Application of TPE/TPR elastomer on two-color plastic cutting board

What is the difference between TPE and TPR. The explanation is as follows: there is basically no difference between TPE and TPR, mainly because of the difference in the way users call them in different regions. Of course, TPE has another layer of meaning, that is, it refers to all kinds of thermoplastic elastomers collectively. 　　As a family wife in the kitchen every day, the monotonous cooking work week after week will make you feel dull and boring. Kitchen utensils you must use every day, here is a recommended fashion cutting board - PP + TPR two-color plastic cutting board, I believe its design can add pleasure to your cooking process. 　　Perhaps the bland is the original color of life, but we always have to decorate it with different colors to make life more colorful. This PP+TPR plastic cutting board is made of food-grade environmental protection PP polypropylene, which can be made into various condensation or warm or bright or simple colors according to the user's preference for colors. The wife of the pursuit of individuality experience, you can buy several different colors of cutting boards at once, of course, the color is their favorite. This way you can use whichever color cutting board you feel comfortable with, depending on your mood. 　　In addition to the various colors available, the two-color cutting board is designed with TPR two-color overmolding. The introduction of TPR thermoplastic rubber with non-slip properties and a different color from the main PP material increases the aesthetic appeal of the product and more importantly makes the cutting board more slip-resistant and shock-absorbing, making it more stable and safe to operate without worrying about sliding or vibration. 　　I believe that this has a high "value" and practical kitchen appliances, the wife knows, will not miss. As for the safety of the material, wives can rest assured that PP polypropylene and thermoplastic rubber TPR are antibacterial food-grade environmental protection materials, in line with FDA testing standards.

TPE/TPR products spit oil/oil analysis

After TPE/TPR materials are processed into products, sometimes there will be products spitting oil|oil analysis (the surface is sticky, and even a layer of oil can be directly wiped out to the hands). This situation, according to the different material mixing system, there may be two different factors, the analysis is as follows. 　　1.TPE|/TPR blending system (lower hardness 0 ~ 20A) oil locking and oil absorption problems 　　General SEBS-based TPE|TPR than SBS-based TPR has a more excellent oil absorption (oil absorption rate). As for SEBS, the oil absorption and oil locking properties of SEBS grades vary with different physical properties (such as butadiene content and different molecular chain structures). Choosing SEBS, especially the SEBS grade with good oil locking property, and choosing the right type of operating oil will reduce the problem of oil spitting on the surface of TPE materials, especially the lower hardness TPE materials (usually the lower hardness TPE materials will be matched with more proportion of operating oil, and the chance of oil precipitation is higher). 　　2.TPE/TPR blending system (higher hardness above 90A) oil precipitation 　　Higher hardness of TPE, especially the SEBS base system of TPE, because the rubber SEBS content in the blending system is relatively reduced, which leads to TPE blending material oil absorption is small, if the blending system to add oil more than a certain limit, it is easy to precipitate out. For some larger size, thinner high hardness TPE products, the possibility of this surface oil spitting problem will be greater. 　　In short, TPE/TPR products surface spitting oil, is basically a problem of TPE, TPR materials, and the user production and processing process is not related. As far as the material is concerned, there are the following three factors 　　First, SBS, SEBS base material and characteristics. 　　Second, the type and characteristics of the operating oil. 　　The third is the process control of TPE/TPR granulation process.

The problem of TPE/TPR injection temperature

The problem of TPE/TPR injection temperature 　　Influencing factors: oil filling rate; SEBS/SBS molecular weight and molecular conformation (linear or star); product thickness; special material formulation and equipment and mold problems, etc. 　　1. The higher the oil filling ratio, the lower the corresponding injection temperature. 　　2. The injection temperature of SEBS base material is higher than that of SBS base material because the thermal stability of SEBS base material is better than that of SBS base material. 　　3. SEBS, SBS molecular weight, high injection temperature; star SEBS / SBS system, injection temperature is higher than the linear SEBS / SBS system. 　　4. For special materials, such as TPE with sticky PA, the introduction of high melting point phase components in the formulation makes the injection temperature higher. 　　5. the injection temperature required for products with large thickness is higher than that for products with thin thickness. 　　6. Equipment type or melt capacity, as well as mold design (including runner, inlet design and the number of cavities in a mold, etc.) will have an impact. 　　In terms of hardness and injection method, the recommended injection temperature range is as follows (the specific temperature is adjusted according to the TPE grade provided by the supplier combined with the actual processing situation). 　　1.TPE hardness 0C~15A super soft material, injection molding temperature 130~200℃; 　　2.TPE/TPR hardness 20~110A single material injection material, recommended injection temperature 140~230℃. 　　3. TPE/TPR covered PP, the recommended secondary injection temperature 170~200℃; 　　4. TPE/TPR encapsulated ABS,PC, the recommended secondary injection temperature is 180~220℃. 　　5. TPE/TPR coated PA, the recommended secondary injection temperature is 240~270℃. 　　6. TPE/TPR coated PS (HIPS, GPPS), the recommended secondary injection temperature is 160~190℃. 　　In short, about TPE/TPR material injection temperature, the general supplier can only give a reference value according to the material type. It should also be combined with the product structure size, processing equipment and mold design and other factors to consider, and gradually adjust the most suitable injection molding temperature according to the actual processing conditions. 　　TPE/TPR shrinkage rate, 1 ~ 3%, low hardness TPE shrinkage rate is larger, other formula system is the same, the filling amount of TPE shrinkage rate is smaller than the filling amount of small TPE/TPR.

Analysis of several adhesive characteristics of TPE/TPR materials

　　Thermoplastic Elastomer (Thermoplastic Elastomer) is an environmentally friendly low-carbon composite material with the characteristics of rubber (high elasticity, compression permanent deformation, etc.) and the processing characteristics of plastic (simple process). (Popularly spoken: thermoplastic elastomer is a rubber with high elasticity, high resilience, but also has the characteristics of injection molding processing, with environmental protection, non-toxic safety, a wide range of hardness, excellent coloring, soft to the touch, weather resistance, fatigue resistance and temperature resistance, superior processing performance, no vulcanization, can be recycled to reduce costs, both secondary injection molding, and PP, PE, PC, PS, ABS (ABS and other substrate materials wrapped bonding, but also can be formed alone. 　　1.TPE material self-adhesive; refers to the TPE material surface has a strong adhesive, similar to the surface coated with glue. This has a strong self-adhesive TPE material can be used to paste everyday items to prevent touching fall or overturn. Similar TPE material, a foreign TPE manufacturer has a special research and development, and applied for a patent. In fact, in the conventional TPE blending system, adding a good compatibility with the main blending system of viscosity enhances the adhesion of the TPE material surface. This kind of adhesion is positive, which is what the user demands and hopes for. 　　2. Adhesion on the surface of soft TPE materials. Some low hardness TPE materials, due to the oil component content in the mix, resulting in a sticky feeling on the surface of soft TPE materials. This sticky feeling is caused by the oil in the formulation. Usually TPE (TPR) based on SBS base is more prone to surface sticky hand problem, this kind of stickiness is negative and is what users want to eliminate. 　　3. Stickiness during overmolding. Adhesion here, refers to the TPE and the wrapped substrate (plastic) due to the close solubility sp or good compatibility, injection molding at high temperatures, the bonding of the two materials in the bonding surface of the fusion bonding effect. The good or bad adhesion mainly depends on the surface affinity of TPE and the covered plastic (similar melting point, close polarity and surface tension, etc.)

TPE/TPR material surface whitening, scratching phenomenon analysis

　　Why does the surface of TPE/TPR material appear white, easy to scratch white phenomenon? 　　Phenomenon one, TPE/TPR materials are not scratch-resistant, easy to scratch white 　　Analysis of the reasons: TPE / TPR production formula filled with white powder material on the side of more, rubber material components to reduce. As the white filler is only physically mixed with the rubber phase, there is no chemical reaction, so it is easy to scrape the white material by hand. For some black and colored products, products scraped white, the phenomenon of non-scraping will affect the appearance of the product. 　　Solution: Use TPE, TPR grades containing relatively little white filler. 　　Phenomenon two, TPE / TPR material surface whitening, a layer of white material, can be wiped away by hand. 　　Analysis of the reasons: TPE / TPR material added additives ①, after a period of time in the TPR products, will gradually migrate to the surface of the product, the formation of a layer of white material. 　　Solution: Reduce the amount of additives added in the TPR formula ②. 　　Remark. 　　①, this kind of additives such as internal lubricant, whitening agent, etc. 　　②, it is recommended to control the addition amount below 3‰. 　　P.S. At present, there is a new enhanced TPE, TPR scratch-resistant formula program, which is to use coupling agent modified heavy calcium instead of ordinary heavy calcium, improve the compatibility of the filler and the substrate, thereby enhancing the white scratch resistance of TPE materials.
