What is the shrinkage rate of TPE/TPU/TPEE/TPV/TPO?

TPE (Thermoplastic TPE (Thermoplastic Elastomer) is a thermoplastic elastomer material, with high strength, high resilience, injection molding processable characteristics, a wide range of applications, environmental protection, non-toxic safety, excellent coloring TPE usually refers to the SEBS, SBS base material blend of modified elastomers. This kind of TPE general shrinkage rate is large, so how much is it? The following will follow the plastic Bo plastic uncle together to understand.

What is SEBS material?

SEBS is a linear triblock copolymer with polystyrene as the terminal segment and ethylene-butene copolymer obtained by hydrogenation of polybutadiene as the intermediate elastic block.SEBS does not contain unsaturated and double bonds, so it has good stability and aging resistance.

TPE,TPR raw materials can pass the food grade FDA 2600 hexane test

With the application of TPE in the field of household and daily-use products in recent years, the environmental requirements for TPE are becoming more and more strict. In the field of household products, especially kitchenware, tableware, small appliances (accessories), coasters (lids) and other products for TPE, TPR demand is long.

TPE/TPR elastomer transparency and its influencing factors

Regarding the flexibility of elastomeric TPEs and TPRs, the choice of components from the dosing system requires only the selection of suitable SEBS, SBS base materials, suitable plastic (e.g. PP, PS) grades, no fillers, toners, flame retardants and other functional additives that can be mixed and synthesized to produce transparent TPE, TPR pellets. However, depending on the specific brand specifications of each component of the system, the distribution ratio of each group will have an impact on the transparency of the TPE and TPR materials. The following is a rough analysis shared.

TPE/TPR thermoplastic elastomer test hardness deviation causes

Hardness is an important performance parameter of thermoplastic elastomer TPE, TPR. For general products, the hardness of TPE and TPR materials is within ±3~5 degrees (A) of the standard hardness. Some products with higher requirements for softness, such as earphone cables, soft TPE products (such as super soft toys with hardness of 0~15A), even require TPE material hardness within ±2 degrees (A) of the standard hardness. Hardness is very important to confirm new product TPE and TPR material samples. Sometimes, inaccurate hardness of material samples may lead to inaccurate sample material hardness, which may result in the sample hardness not meeting the customer's requirements.

TPE,TPR elastomer becomes the preferred raw material for fitness equipment

In recent years, public health awareness has gradually increased, which has also brought business opportunities to the market. Shrewd businessmen are always good at grasping opportunities. Nowadays, many goods are related to health, such as massage pillows, magnetic therapy stickers, meridian massage brushes, foot massage mats, massage insoles, yoga mats and so on. Shibe found that a lot of massage and fitness equipment, actually use thermoplastic elastomer TPE / TPR as raw materials. As a material that needs to be in close contact with people, TPE/TPR elastomer is non-toxic and safe?
