Addition Cure Silicone Rubber

Silicone rubber means that the main chain is composed of alternating silicon and oxygen atoms. A rubber having two organic groups attached to a silicon atom. Ordinary silicone rubber is mainly composed of a silicone chain containing a methyl group and a small amount of a vinyl group.
Addition Cure Silicone Rubber is mainly based on polydimethylsiloxane containing terminal vinyl groups, and the polymethylsiloxane containing dimethyl and methyl hydrogen links is used as a crosslinking agent and platinum. The complex is a compound made of a crosslinking catalyst. The rubber compound is subjected to an addition reaction under the action of a catalyst at room temperature or under heating to obtain a network-like silicone rubber. Addition Cure Silicone Rubber is a two-component addition molding silicone material that can be cured at room temperature or warmed.
1. Low shrinkage rate, no low molecules are released during the cross-linking process, so the volume is constant and the shrinkage rate is less than 0.1%;
2. Not limited by the thickness of the product, can be deep curing;
3. It has excellent high temperature resistance, the temperature can reach 300-500 degrees;
4. Food grade, non-toxic and tasteless, passed FDA food grade certification;
5. High tensile, tear resistance, more times of mold;
6. Good fluidity, easy to infuse; can be cured at room temperature can also be heated and cured, easy to operate.
