It is made of polyether polyurethane elastomer as the base material, adding high-efficiency flame retardant and other processing aids, and is made by mixing, plasticizing and granulating. It has excellent properties such as halogen-free, high flame retardant grade, high resilience, hydrolysis resistance, heat resistance, weather resistance, and oil resistance. It can also add 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
2. Low density
3. Excellent oil resistance
4. Excellent elasticity and soft appearance
5. Good hydrolysis resistance

Notes:
1. When the storage environment is humid or the surface quality requirements are high, the pellets can be placed in a hot air hopper at 90°C to dry for 1~2 hours.
2. The screw should be cleaned before extrusion to ensure the cleanliness of the product. It is recommended to use an 80-mesh or 100-mesh filter.
