Meaning and Definition
A synthetic rubber made by copolymerizing isobutylene with a small amount of isoprene, known for its excellent impermeability to gases.
A type of synthetic elastomer primarily valued for its low gas permeability, making it ideal for inner tubes, seals, and pharmaceutical stoppers. It also exhibits good resistance to heat, weathering, and chemicals.

Frequently Asked Questions
No, they are different synthetic polymers. Butyl rubber is based on isobutylene and is prized for gas impermeability. Silicone rubber is based on silicon-oxygen chains and is known for high temperature resistance.
Yes, but it is more challenging than recycling some other rubbers. It is often done through devulcanisation or used in asphalt modification.
It is a type of butyl rubber that has been treated with chlorine or bromine. This process improves its curing compatibility with other rubbers (like natural rubber) and enhances its heat resistance.
