Introduction to Butyl Rubber, Main Applications of Butyl Rubber

2022-06-17

Butyl rubber is a synthetic rubber obtained by copolymerizing isobutylene and a small amount of isoprene. One of the isoprene rubber), the English name is Butyl Rubber, referred to as IIR (abbreviation of Isobutylene Isoprene Rubber). White to light gray, odorless and tasteless; insoluble in ethanol and ether. Viscosity average molecular weight=(35-45)×l04, relative density (17℃/4℃) 0.92, (27℃/4℃) 0.91, refractive index 1.5078～1.508l, glass transition temperature -69℃, specific heat capacity 1.94kJ/ (kg K), thermal conductivity 0.091W/(m.K). The isoprene segment only accounts for 0.6% to 3.0% of the main chain, so the butyl rubber has a high degree of saturation in the chain.

After the inner tube is loaded, the air pressure is above 8MPA, and the high air tightness of the carcass reduces the natural leakage of gas. Compared with the natural rubber inner tube, the inflation frequency is reduced during use, and it is more fuel-efficient during driving. The high temperature resistance of butyl rubber inner tube is better than that of natural rubber inner tube. When the car is running at high speed for a long time, the temperature of the inner cavity of the tire is very high, which makes the inner tube rubber rapidly self-vulcanize and affects the service life. Butyl rubber inner tube is more resistant to aging, and the use time longer.

※ Butylation is the development trend of the global inner tube; ※ Butyl inner tube has excellent air retention, and its air retention rate is more than ten times that of natural rubber; ※ The use of butyl rubber inner tube can improve the crown life of the outer tire and reduce the rolling resistance; ※ The butyl inner tube has excellent tear resistance and heat resistance, all-weather resistance and self-oxidation resistance, and excellent resistance to adverse environmental performance; ※ Identification method of butyl inner tube: blue line; ※ The butyl rubber product can effectively absorb the vibration energy, drop the pen from a height, if the pen does not bounce up, it is a butyl inner tube, and it bounces up as an imitation.
