Product Description: CERAMIC SILICONE RUBBER
●Under high-temperature condition of fire, they will not melt and can form a hard ceramic layer, with flame retardancy and high temperature resistance.
Applications:
● Refractory sealing strips
● Refractory sealing gaskets
● Cable and wire
Transportation, safety and storage precautions:
●The product should be kept away from rain and sunshine, away from fire and heat sources, stored at room temperature, not in contact with air, and avoid contact with strong acid, strong alkali, metallic lead and its compounds. Avoid contact with organic compounds containing N, P, S and organotin catalysts. Packaging requires sealing, careful loading and unloading during handling to prevent damage to packaging and containers.
●This product cannot be added to a variety of silicone materials containing hydrogen silicone oil as an anti-yellowing agent special vulcanizing agent, otherwise the rubber material will appear hardening, refining is not shaped, pitting, gel and other self-sulfurization phenomena.
●Unused products should be stored sealed to avoid contamination. The shelf life of the product is 9 months from the date of manufacture.
