High Quality Butyl Rubber Molded Products OEM

Butyl rubber has good chemical stability and thermal stability, and the most outstanding are air tightness and water tightness. Its air permeability is only 1/7 of that of natural rubber and 1/5 of that of styrene-butadiene rubber, while its steam permeability is 1/200 of that of natural rubber and 1/140 of that of styrene-butadiene rubber. Therefore, it is mainly used for manufacturing various rubber products such as inner tubes, steam pipes, water tyres, dam bottom and gaskets.

Butyl rubber (IIR) is the fourth largest synthetic rubber (SR) rubber in the world. It is the product of cationic polymerization of isobutene and isoprene under the action of Friedel-Craft catalyst. It is white or light yellow crystal in appearance, odorless and tasteless, has a low glass transition temperature, and is insoluble in ethanol and acetone. Butyl rubber is widely used in inner tubes, water tubes, vulcanized capsules, airtight layers, sidewalls, wires and cables, waterproof building materials, damping materials, pharmaceutical bottle stoppers, food (gum base material), rubber dams, anti-poison appliances, adhesives, inner tube valve cores, anti-corrosion products In terms of wharf ship protection, bridge support pad and heat-resistant transport belt.
