Butyl Rubber(IIR)

Butyl Rubber: Excellent air retention, Shock Absorption Rubber Part Solution

Butyl rubber is a unique elastomer with a range of unique properties, the most notable of which is its excellent air tightness and excellent weather and ozone resistance. Weather resistance can be used for door and window weatherstrips and seals, and O-rings are another common application, widely used in countless mechanical equipment. In engines, pumps, and hydraulic systems, O-rings made of butyl rubber can form a tight seal to prevent liquid and gas leakage.

Butyl rubber also has excellent shock absorption properties and is resistant to heat, chemical corrosion, bending, abrasion, and tearing. It can withstand phosphate-based hydraulic fluids, resist punctures, and has excellent electrical insulation properties. Although its oil resistance is limited, its unique advantages make it an indispensable material in a variety of professional applications in many industries.

We offer a wide range of butyl rubber products custom-made to meet the needs of various industries. Looking for butyl rubber parts like seals, gaskets, or linings? We can create exactly what you need. Our team will work closely with you to understand what you need and provide a custom part that works well and fits your budget.

What is Butyl Rubber Made Of?

Butyl rubber is made from the copolymerization of isobutylene and a small amount of isoprene. In the production process, these two monomers are combined under specific conditions to form the polymer chains that make up butyl rubber. Isobutylene, a hydrocarbon compound, serves as the main component, contributing to the rubber's unique properties such as low gas permeability and good chemical resistance. The Pierce-Roberts Butyl rubber, a notable variant in the butyl rubber family, exhibits exceptional resistance to abrasion. This property is vital in applications where the rubber is constantly subjected to friction. It can withstand the rough handling and continuous rubbing against various materials without significant wear and tear.

These properties make butyl rubber an excellent choice for a variety of applications and industries. Butyl rubber is widely used to fabricate many different components. Inner Tubes, Sealing Rings and Gaskets, Bottle Stoppers, Sealants, Fuel Tank Seals, and so on. In today's global rubber market, butyl rubber has firmly established itself as one of the most commonly used synthetic rubber compounds.
