Problems solved by technology

[0002] Thermoplastic polyether ester elastomers are widely used in the field of cables due to their comprehensive properties such as outstanding mechanical strength, excellent resilience and wide service temperature, but their shortcomings such as flammability and droplet seriously affect its Application and promotion
In addition, the long-term working temperature of the current thermoplastic polyether ester elastomers is mostly at 125°C, which still does not meet the requirements for high temperature resistance of 150°C
[0003] High-density polyethylene (HDPE), EPDM rubber (EPDM), high-temperature resistant resin and halogen-free flame retardant are used as raw materials. The combustion performance has been improved, and it can be used for a long time at 150 ° C, and the oxygen index reaches more than 31%, but its mechanical properties are poor, especially the crack resistance cannot meet the use requirements.
