Recently, bromobutyl rubber produced by Yanshan Petrochemical's own R&D process technology has been successfully used as an alternative to imports to achieve full production and sales. Up to now, the company has produced 1200 tons of bromobutyl rubber.
Brominated butyl rubber is an essential raw material for the production of tubeless radial tire inner liners for vehicles. Its processing performance, serviceability and product prices are all superior to those of ordinary butyl rubbers. Previously, domestic use of bromobutyl rubber was all dependent on imports. Yanshan Petrochemical insisted on highlighting product features, successfully developed a bromobutyl rubber technology package with independent intellectual property rights, and built the first domestic 30,000-ton/year bromobutyl rubber production plant.
After the plant was put into operation, Yanshan Petrochemical successively placed brominated butyl rubber produced in the domestic tire manufacturing and pharmaceutical fields for trials and achieved success. Users reflect that their performance is comparable to that of foreign brands. At this point, Yanshan Petrochemical broke the domestic use of high-end halogenated butyl rubber completely dependent on the import situation, successfully achieved localization of bromobutyl rubber.
