Bromobutyl rubber is an isobutylene-isoprene copolymer elastomer containing active bromine. With excellent air tightness, damping, heat resistance, KHUYẾN MÃI FB88emical resistance, and ozone aging resistance, as well as good vulcanization performance and compatibility, it can be widely used in tires, medical plugs, anticorrosive lining, protective clothing, shock-absorbing parts, shoe materials, and other fields.
1. Excellent airtight performance: Its air permeability is 1/7 of natural rubber, and 1/5 of styrene-butadiene rubber, makKHUYẾN MÃI FB88g air pressure KHUYẾN MÃI FB88 tires sufficiently stable to ensure long periods of drive and promote low-carbon life.
2. Easy to process and more environmentally friendly: KHUYẾN MÃI FB88ambroad Sinopoly’s new bromobutyl rubber can reduce the amount of humidity in the production process through improvements in product purity and molecular weight distribution, thus more environmentally friendly.
3. Greater applicability: Specially designed for waterproofKHUYẾN MÃI FB88g, electrical appliances dampKHUYẾN MÃI FB88g, sportKHUYẾN MÃI FB88g goods, and other emergKHUYẾN MÃI FB88g markets.
