Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a halogen-free flame-retardant thermoplastic elastomer cable material for new energy vehicles. Background technique [0002] With the increasing energy crisis and environmental pollution, the development and promotion of new energy vehicles has gradually attracted the attention of countries all over the world. As an important part of new energy vehicles, hybrid vehicles and pure electric vehicles have developed rapidly in recent years. Different from traditional fuel vehicles, electric vehicles have a lot of high-voltage and high-current power electronic devices inside. Therefore, the safety of automotive cable materials is even more important, especially the flame-retardant performance is the top priority. In addition, during the use of automobile cables, long-term stretching and bending will cause the cable materials to age. [0003] Thermoplastic elastomer (thermoplas...
