GR-ECR-2050 is a kind of synthetic rubber foaming material, which not only has good physical properties of special rubber, but also has excellent properties such as flame resistance, oil resistance, chemical corrosion resistance, etc. Therefore, it occupies an important position in the field of power battery/new energy.
Main features:
1, lightweight, strong and tough, with good tear strength;
2. It has good insulation and low thermal conductivity, and is an excellent thermal insulation material;
3. It has low water absorption and independent bubble structure, so it is a material with low water absorption;
4, Buffering, with good elasticity, can be used as buffer/shock absorption materials;
5. Excellent weather resistance; Excellent weather resistance,
(After 168 hours of weather resistance test, ECR foam has no abnormality after [500PPHM * 38 degree lengthening 20%].
6. Flame resistance, fire rated test qualified products (ECR foam is UL94 V0 qualified products)
