Gongyi HuanZhong Pipeline Equipment Company is specialized in rubber expansion joint producing. Reducing Rubber Expansion Joint is widely used in many pipeline using industry to provide protection with its large flexibility. What’s more, the rubber body can also be made of different materials, which will also contribute to various functions. IIR rubber joint is made of special rubber material IIR, so it's of different features.
IIR is the copolymer of isobutylene and a small amount of isoprene or butadiene. The biggest feature of IIR is good air tightness, ozone resistance, aging resistance, good heat resistance. Long-term working temperature can be below 130 DEG C; excellent inorganic acid (such as sulfuric acid, nitric acid, etc.) and organic solvents resistance, ceiling has good vibration and damping characteristics, electrical insulation is also very good. The disadvantage is poor elasticity, poor processing performance, slow curing speed, poor adhesion and oil resistance. Temperature range: about -40℃ ~120 ℃. Mainly used for inner tube, water births, balloons, wire and cable insulation layer, chemical equipment lining and shockproof products, heat resistant conveyor belt, heat aging of adhesive tape products.
Different rubber materials are of different features and functions, to make best use of the rubber joint, knowing the features of rubber material is very important to customers.
