Abstract
The invention provides an oil-less environment-friendly type TPE (thermoplastic elastomer) headset wire. The oil-less environment-friendly type TPE headset wire is characterized by being prepared from raw materials in percentage by weight as follows: 30%-70% of SEBS (styrene-ethylene-butylene-styrene), 5%-30% of EPDM (ethylene-propylene-diene monomer), 1%-15% of PP (propene polymer), 5%-25% of POE (polyolefin elastomer) and 2%-10% of auxiliaries. A traditional SEBS processing technology giving priority to an oil charge system is changed, SEBS with low molecular weight is taken as a main material, high-fluidity resin such as EPDM, POE and the like is added, the processing conditions are improved, and the physical performance is enhanced.
