In the field of electronic wire, TPE is the preferred material to replace PVC.
At present, 90% wire and cable products on the market are using PVC as protective layer. The main reason is that PVC wire and cable materials are simple, mature and low cost, and can produce different soft hardness products with better comprehensive performance. However, PVC is not environmentally friendly, in the production of PVC wire and cable formula technology, many companies are still adding toxic substances (heavy metals such as lead, cadmium, chromium and other heavy metals) and high carcinogens, especially in less developed countries. The plasticizers added in PVC production are mostly environmental hormones, which affect development and fertility. There are many restrictive regulations on the use of children's toys in Europe and America on the use of PVC. Because the PVC production process is not environmentally friendly, many developed countries in the world no longer invest in the PVC plant, and the existing capacity is also decreasing.
With the European Union ROHS, a mandatory standard enacted by EU legislation, its full name is "instructions on limiting the use of certain harmful components in electronic equipment"), REACH (EU regulation "registration, assessment, authorization and restriction of chemicals") implementation of environmental laws, environment and living safety The environmental protection requirements of electronic and life products are getting higher and higher. The application of PVC plastics will be more and more restricted. Therefore, the development of halogen free flame retardant and environmentally-friendly wire and cable is undoubtedly of great significance. At present, in the field of electronic wire, TPE has been considered by many professionals to be the first choice for PVC.
It is understood that TPE is a thermoplastic elastomer with both plastic and rubber properties. It is made from a wide range of thermoplastic elastomers, such as styrene - ethylene butadiene styrene block copolymer (SEBS), modified by polypropylene (PP). TPE has the characteristics of high elasticity, high strength, low density, easy processing and so on. It also has good insulation, high temperature resistance, fatigue resistance, good hand feeling and no odor.
