Product Description:
80℃ TPU charging pile cable sheath material is based on polyether polyurethane elastomer, added with high-efficiency flame retardant and other processing aids, and is made by mixing, plasticizing and granulating. It has excellent performance such as halogen-free, high flame retardant grade, high resilience, hydrolysis resistance, heat resistance, weather resistance and oil resistance, and can add matte matte, frosted and other effects according to customer needs; no precipitation pollution, in line with ROHS and other relevant requirements.
Product features:
1. High flame retardancy (single vertical)
2. Low density (below 1.20g/cm3)
3. Excellent oil resistance
4. Excellent elasticity and soft appearance
5. Good hydrolysis resistance
6. Good wear resistance and heat resistance
7. Meet SGS, ROHS and other requirements
Application areas: Suitable for charging pile charging cables.
