TPE is a material with high elasticity, high strength, high resilience of rubber and the characteristics of injection molding. The invention has the advantages of environmental protection, innocuity, safety, wide application range, excellent coloring property, soft touch feeling, weather resistance, fatigue resistance and temperature resistance, excellent processing performance, no need of vulcanization, recycling, cost reduction, secondary injection molding, coating and bonding with PP, PE, PC, PS, ABS and other matrix materials, or separate molding. What are the differences between TPE raw materials and TPR raw materials? We will make a few for your reference below.
1. The surface of TPE particles is foggy or matte
2, has the light irradiation astigmatism
3. TPR particles are bright
4. It has light reflection, especially the transparent material is more obvious.
5. TPE feels comfortable and smooth
6. TPR is a bit sticky
7, some products that need to be bonded with glue, such as shoes, handicrafts, toy figurines, etc., generally use TPR material, because TPR and glue are bonded firmly, while TPE material and glue are almost non-sticky. In addition, TPR is easy to match colors, and is suitable for making products with bright colors and bright surfaces. TPE and TPR both have plasticity of plastic and elasticity of rubber, while TPR molecule has unsaturated molecular structure similar to rubber, so it has more hand feeling and resilience of rubber.
8. The difference between TPE and TPR combustion: TPE combustion produces light smoke, while TPR combustion produces dark smoke. TPR is more difficult to plasticize and process than TPE.
