The shape size can be accepted by non - standard customization.
The fireproof ring fire retardant silica gel belongs to the TN-59XXU series, and the flame-retardant property of the fireproof ring silicone rubber is UL94 V-0, which is suitable for the molding process and the extrusion process. The flame retardant silica gel has excellent resistance to high and low temperature, electric insulation, flame retardancy and aging resistance. It is widely used in wire and cable industry, such as wire and cable with high and low temperature and high insulation, and the coating material of atomic energy device wire and cable is used as silica gel material.
Flame retardant silicone rubber advantages:
1: good flame retardancy
2: good processing performance
3: good physical performance
