● Good physical, mechanical and electrical properties
● Superior flame retardancy and self-extinguishing property
● The flame retardancy of 2mm test piece can reach the class V-0 stated in the national standard IEC 60695-11-10.
● Complies with the requirements of ROHS
Applications:
●Used for silicone rubber products with high flame retardant requirements and low specific gravity requirements, such as flame retardant foamed silicone rubber.
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.
