RTV silicone rubber
- Benchmark: Benchmark 2
- Assessed: 2015-06-25
Used primarily in and Plasticizers & Polymer applications, RTV silicone rubber is specifically used in binding agent, and silicone rubber.
In general, RTV silicone rubber is a room temperature vulcanized silicone rubber, which requires crosslinking at elevated temperature to produce the cured rubber. It has a relatively low molecular weight and typically consists of a viscous hydroxyl-terminated silicone resin and tetraethyl orthosilicate (TEOS), the crosslinking agent. When reacted together, they form silicone rubber (Honey Silicone 2011). The CAS number of 11099-06-2 refers to the tetraethyl orthosilicate polymer according to ChemIDplus and Pharos databases. It is considered by Environment Canada as a UVCBs-organic substance (Environment Canada 2013).
Chemical Synonyms Ethyl silicate; Polysilicic acid, ethyl ester; Silicic acid (H4SiO4), tetraethyl ester, homopolymer; Silicic acid, tetraethylester polymer; Tetraethyl orthosilicate polymer; Silicic acid, ethyl ester (ChemIDplus 2015)
