Thermoplastic elastomer TPE/TPR products, when touched by hand, the surface is sticky, even some sticky feeling. What is the reason for this? Why is this?

　　Thermoplastic elastomer TPE / TPR products made of sticky surface causes.

　　1. The amount of operating oil is too much. Operating oil is one of the essential components, the addition of operating oil can improve the plasticity of the material. The main hardness of TPE/TPR material ranges from 0 to 100 degrees (ShoreA, the same as below), generally speaking, the softer the material, the more the amount of operating oil added, but we should pay attention to the right amount.

　　The TPE/TPR of SEBS base material is less sticky than the SBS base material, and the TPE/TPR of SBS base material is easy to stick to the hands, which is more obvious in the case of high temperature. The products made of TPE/TPR granules are also sticky. The TPE/TPR products made of SEBS base material, except for the super soft material with hardness below 15 degrees, will rarely appear sticky hands.

　　Thermoplastic elastomer TPE/TPR products made of sticky surface Optional solutions.

　　1. Choose TPE/TPR material with SEBS base material;

　　2. Select the appropriate operating oil, improve the SEBS blending system TPE / TPR formulation, can greatly reduce the sticky products;

　　3. The processed super soft TPE/TPR products will slowly improve the sticky surface after being placed for a period of time.
