TPE terminal wires will replace PVC terminal wires. At present, 90% of the terminal wires, wires and cables on the market use PVC as a protective layer. The main reason is that the PVC wire and cable materials are simple, mature and low-cost, and can be manufactured with different soft Hard products have better overall performance. However, PVC terminal wires are not environmentally friendly. Many companies are still adding toxic substances (heavy metals such as lead, cadmium, chromium, etc.) and highly carcinogenic substances in the formulation process of producing PVC wire and cable materials. This phenomenon is especially obvious in less developed countries. . The plasticizers added during the production of PVC are mostly environmental hormones, which affect development and fertility. There are many restrictive regulations on the use of PVC in the manufacturing materials of children's toys in Europe and the United States. Due to the serious unenvironmental protection of the production process of PVC materials, many developed countries in the world no longer invest in PVC factories, and the existing production capacity is gradually decreasing.
The TPE terminal wire will replace the PVC terminal wire. With the EU ROHS (a mandatory standard established by EU legislation, its full name is "The Directive on Restricting the Use of Certain Hazardous Components in Electronic and Electrical Equipment"), REACH ( The abbreviation of EU regulations "Registration, Evaluation, Authorization and Restriction of Chemicals") The implementation of environmental protection regulations, people's attention to the environment and life safety, the increasing environmental protection requirements of electronic and living products, the application of PVC plastics will be affected More and more restrictions. Therefore, the development of halogen-free flame-retardant environmentally friendly wire and cable is undoubtedly of great significance. At present, in the field of electronic wire, TPE terminal wire has been considered by many professionals as the preferred material to replace PVC terminal wire.
TPE terminal wire is a kind of thermoplastic elastomer with both plastic and rubber characteristics. It is made of styrene-ethylene-butadiene-styrene block copolymer (SEBS), a widely-used thermoplastic elastomer, through polypropylene (PP) made by modification. TPE has the characteristics of high elasticity, high strength, low density, and easy processing. At the same time, it has good insulation, high and low temperature resistance, fatigue resistance, good hand feeling, and no odor.
