IIR butyl rubber expansion joint

IIR butyl rubber expansion joint is a high performance pipe connection component,

Widely used in various industrial fields.




It's made of isobutylene and a small amount of isoprene,

With excellent air tightness, heat resistance, aging resistance,

Ozone resistance, solvent resistance and chemical stability.

IIR butyl rubber expansion joint is an ideal choice for processing crude oil, refined oil, natural gas and other media.


The working principle of IIR butyl rubber expansion joint mainly depends on its excellent elasticity and sealing performance.

It absorbs pressure shocks and vibrations from inside and outside the pipe,

Effectively compensate the displacement and deformation of the pipeline, 

thus ensuring the stability and safety of the pipeline system.

At the same time, its high air tightness reduces the risk of 

water leakage due to pipeline deformation and improves the overall reliability of the pipeline system.


In the pharmaceutical and food processing industries, IIR butyl rubber expansion joints also perform well.

Piping materials in these industries must meet strict hygiene requirements,

And it needs to be resistant to the disinfectants and chemicals used in cleaning.


IIR butyl rubber expansion joint contains no harmful additives,

And has excellent chemical resistance,

So we can meet the high standards of these industries,

Ensure the purity of the conveying medium and the durability of the equipment.


IIR butyl rubber expansion joint also has good resistance to high and low temperatures.

It works efficiently in extreme temperature conditions,

For example, in high temperature and high pressure environments or in systems requiring shock absorption and noise reduction.

This makes IIR butyl rubber expansion joint widely used in HVAC, Marine, mining and other fields.
