S3021 Low density silicone rubber foam
- Detailed
Description
Low density is a kind of compressible polymer elastomer material made by mixing evenly and special technology, which is made of raw materials including silicone rubber, filling and reinforcing agent, vulcanization promoter and foaming agent. It is used for shock absorption, buffering, sealing, heat insulation, sound insulation and other protection of high-speed railway, locomotive, high-pressure assembly, outdoor waterproof, lamps and household appliances.
