AI Technical Summary

Problems solved by technology

[0003] (1) The mechanical properties of the core wire material made of general flame-retardant TPE are acceptable, but the resistance to high temperature resistance during tin immersion is insufficient, and the phenomenon of not being resistant to melting loss often occurs;
[0004] (2) The cable made of ordinary flame retardant core wire material is not strong enough due to the high content of flame retardant, and it is easy to break during the swing test;
[0005] (3) The compatibility of thermoplastic polyester elastomer TPEE and flame retardants is general, and it is often difficult to meet actual needs
