Butyl rubber compound (IIR)

Butyl rubber compound (IIR)

It is a synthetic rubber material made of isobutylene and a small amount of isoprene. After adding vulcanizing agent, reinforcing agent, softener and other additives in the mixing process, it can be directly used for product molding. Its core advantages are extreme air tightness, excellent aging resistance and damping shock absorption. It is the core material for high-end sealing, shock absorption and air tightness applications.
Product Features
Features:Excellent air tightness and water tightness, heat resistance, aging resistance, acid and alkali resistance, and good electrical insulation

Disadvantages:Poor elasticity, weak adhesion, slow curing speed

Application:Inner tube, steam hose, waterproof coiled material, medicinal bottle stopper, shock absorbing pad

Product Description

Extreme air tightness

The air permeability is only 1/7 of that of natural rubber, and the vapor permeability is 1/200 of that of natural rubber.

The molecular structure is dense and the gas molecules are extremely difficult to penetrate. It is the preferred material for tires and airtight parts.

Excellent weathering and aging resistance

The main chain is highly saturated and the ozone resistance is 10 times that of natural rubber.

Weather resistance, heat oxygen aging, long-term use is not easy to crack, softening.

Wide operating temperature range:-60 ℃ to 130 ℃.

Strong chemical stability

Resistant to most inorganic acids, alkalis, polar solvents and animal and vegetable oils.

It is not resistant to concentrated oxidizing acids (such as concentrated nitric acid) and petroleum-based oils.

Excellent damping shock absorption

Very low rebound rate (<20%), can efficiently absorb vibration and impact energy.

Widely used in shock absorption pads, machine foot pads, sound insulation parts.

Good electrical insulation

High volume resistivity, suitable for high-voltage cables and insulating seals.
