With the continuous development and improvement of the thermoplastic elastomer TPE material industry, it has gradually been used in various industries, and the requirements for materials are becoming increasingly strict, such as the research and development of special materials such as flame retardant, high elasticity, and abrasion resistance. With the continuous improvement of materials and the continuous introduction of new products, the demand for conductive grade TPE materials is also an inevitable result of market development. With the development of the market, the thermoplastic elastomer industry will become increasingly colorful, providing better and more comfortable materials for people's lives.

Currently, most of the TPEs in the market focus on anti static electricity. To truly achieve conductive level, there are still high requirements for technical research and development. There are not many enterprises in China that can conduct conductive TPE product research and development. The above reasons also force the world to turn to the development of bio based substitutes for synthetic thermoplastic elastomers to meet the growing market demand for clean thermoplastic elastomers, which is also a more economical solution.

Conductivity of TPE. According to the surface resistance value of the material, TPE can be divided into the following three classes in terms of dielectric properties:

Insulation grade TPE refers to products with a surface resistance value of more than 10 to the 13th power

The surface resistance of the product reaches between 5 and 12 powers of 10, which is an anti-static TPE

 Conductive grade TPE refers to the product with a surface resistance value below the 5th power of 10.

There are certain differences between antistatic TPE and conductive TPE. Generally, TPEs are antistatic grade materials. In terms of electrostatic protection, in practical cases, the surface resistance values of products required by different customers may vary, and sometimes there may be certain restrictive requirements for the TPE mixing system. To make TPE conductive, special material modifications are needed. TPE and rubber have a certain degree of similarity in the molecular chain structure, and according to the above rubber modification ideas, TPE seems to be able to imitate. However, it is necessary to fully consider the similarities and differences between TPE mixing systems and silicone rubber. The blending system of TPE is relatively complex, and it is necessary to consider the compatibility of each component phase structure, the uniformity of blending dispersion, and so on.
