Butyl rubber is synthesized by cationic polymerization of isobutylene and isoprene. It is mainly used in inner tube, bladder, sealing products, butyl coil and other fields.
BIIR is a special synthetic rubber with good air tightness and excellent chemical stability. It is mainly used in air tightness of tires to increase the life cycle of radial tires and help the development of eco-friendly tires. At the same time, (halogenated) butyl rubber is an irreplaceable raw material for pharmaceutical stoppers under the category of antibiotics, which safeguards people’s health.
CIIR relies on the chlorination reaction process of butyl rubber independently innovated and developed by Chambroad Research Institute. Its chlorinated butyl rubber was put into mass production and successfully marketed in 2022. The product has better stability, better underwater environmental performance, and more resistance to fatigue, light, heat and ozone aging.
Styrene Butadiene Latex
The cationic SBR latex, jointly developed with Dalian University of Technology, is a stable emulsion formed by polymerization of butadiene and styrene. It excels in adhesion, stability and liquidity. It is an emulsion polymer specially used for modified emulsified asphalt, which is synthesized by appropriately adjusting the polymerization process according to the characteristics of asphalt. When SBR latex is applied to modify emulsified asphalt, it can reduce the temperature sensitivity of asphalt and has a good elasticity performance. It can increase the low-temperature ductility of asphalt and has better high-temperature performance. It is easy to use and has excellent performance.
