The Butyl Rubber Molding Experts
Butyl rubber molding is often used for outdoor applications because of its excellent weather and abrasion resistance. Also recommended for its ability to resist gases, inorganic acids and alkalis. Butyl is a non-pliable polymer/elastomer.
Butyl processed via rubber molding has excellent sealing properties and is a suitable choice for the manufacture of seals for chemical condensers. It is widely used in the electronics industry.
- Good sealing properties
- Resistant to electrolyte solvents
- Low compression set
What is Butyl Rubber?
Butyl rubber, also known as isobutylene-isoprene rubber (IIR), is a versatile, general purpose, synthetic rubber and a copolymer of isobutylene with isoprene. Butyl rubber is produced by polymerization of about 98% of isobutylene with about 2% of isoprene. It is ideal for shock absorption, offers particularly low gas and moisture permeability, exceptional resistance to heat, weather, ozone, abrasion, tearing, chemical corrosion and much more.
Butyl rubber is impermeable to air, so it is useful in many applications requiring an airtight rubber. Butyl’s strength, flexibility, low gas permeability and airtight characteristics mean it is also ideal for high pressure or vacuum sealed applications. The first widespread application of butyl rubber molding, however, was tire inner tubes. This application is still central for butyl rubber molding to this day.
Butyl is an incredibly versatile synthetic rubber. However, it is not recommended for use in applications involving contact with petroleum oils.
