In fact, TPE is the general name of all thermoplastic strong elastomers, but the subdivision can be divided into TPE, TPR, TPU, TPO, TPV, etc. About the material difference between TPE and TPR, many people ask this question, do not know how to choose the material, in order to facilitate the selection of materials, yamanjin chemical TPE and TPR material difference to introduce：
1 TPE,TPR substrate is different, TPE is SEBS as the substrate,TPR is SBS as the substrate.
2 Production process :TPE processing temperature slightly higher than TPR.
3 Weather resistance is different,TPE weather resistance is better, TPR is relatively poor.
4 Appearance TPR is bright TPE sublight, feel good.
The same point is that TPE and TPR have better resilience and low temperature resistance. The theory of low temperature resistance is -60 ° c, and generally -40 ° c is no problem with different formulas. Generally, the long-term temperature of high temperature resistance is 80 ° c.
About how to select materials, generally more indoor TPR, more outdoor TPE. Requirement feels good, inferior light USES TPE, bright light USES TPR, high-grade product USES TPE commonly, low grade USES TPR, about medium grade that from already looking at do!
TPE and TPR are personalized materials, and the formula is customized according to the actual situation of customers. For different purposes and different production processes,TPR and TPE should be subject to the sample. Any TPE and TPR is not all-powerful.
