Health Information The health hazards of Butyl Rubber polymers at ambient temperature are generally negligible. They are not toxic, corrosive, sensitizers, reproductive toxins, or mutagenic, neurotoxic, or carcinogenic, and do not cause specific target organ effects.
What is butyl sealant used for?
Basic Uses Tremco Butyl Sealant is used for sealing joints in applications such as curtainwall joints, metal panel joining, bedding thresholds, secondary glazing seals, and areas where a seal is required against Tremco Neoprene or EPDM gaskets.

What is butyl made of?
Butyl alcohol. Commercial n -butyl alcohol is made by fermentation of corn (maize) or molasses or by condensation and reduction of acetaldehyde. sec -Butyl alcohol is produced from butene by reaction with sulfuric acid, followed by hydrolysis . t -Butyl alcohol is similarly produced from isobutylene (2-methylpropene).
Is polyisobutylene a form of butyl rubber?
Butyl rubber, or polyisobutylene, is a vinyl elastomer very similar to polyethylene and polypropylene in its structure, except that every other carbon atom is substituted with two methyl groups rather than one. It is made by a process called cationic vinyl polymerization from the monomer isobutylene.
What is butyl sealant?
Tremco Butyl Sealant is used for sealing joints in applications such as curtainwall joints, metal panel joining, bedding thresholds, secondary glazing seals, and areas where a seal is required against Tremco Neoprene or EPDM gaskets.
What are butyl tubes?
Butyl tubes are made from synthetic black rubber , while latex tubes are made from the sap obtained from rubber trees. This rubber is far more fragile than butyl and owing to more time-consuming production, latex tubes are more expensive too.
