Problems solved by technology

[0002] Usually, silicone rubber itself is not flame retardant or fire-resistant. In a fire accident, wires and cables are not fire-resistant and easy to burn in case of fire. This field lacks a fire-resistant silicone rubber. It is required not only to have the excellent characteristics of rubber during normal use, It also has good flame retardancy and fire resistance. The products made by using it can play a certain protective role in the fire, and can reduce the losses caused to people in the fire and reduce the harm.
