Features of CR of Thread Rubber Expansion Joint
Gongyi Xinli Pipeline Equipment Company is a professional manufacturer in rubber expansion joint manufacturing with more than 20-year experience. CR is one of the most common material used in threaded rubber expansion joint producing. The features of CR are as follows:
CR is a kind of multi purpose elastomer with good comprehensive properties. It’s of good tensile strength, excellent physical toughness; good heat resistance, ozone resistance, weather resistant and aging resistance, especially, it’s heat resistance is better than nitrile rubber sheet; weather and aging resistance is better than EPDM rubber sheet; What’s more, CR is also of good resistance to oil and chemical corrosion and flame retardancy with 38-41oxygen index.Usually oxygen index reached 27 of the material is difficult to burn, usually containing a sufficient concentration of halogen rubber plate are flame retardant. Oxygen index is a measure of the burning material performance index, the definition is refers to the specimen in the mixture of nitrogen and oxygen gas maintain candle like combustion required minimum oxygen volume; chloroprene rubber sheet of the oxygen index is very high, very difficult to burn.
Chloroprene rubber is mainly used in inflaming retarding, adhesion, heat resistance, weather resistance, medium electric resistance etc., Such as wire and cable, adhesive, bridge bearings, fire retardant and ducting, auto parts, coatings, corrosion resistant lining. Chloride rubber plate can be used for power plants, sewage treatment, chemical plants and other corrosion resistant and high temperature resistant, weather resistant places, etc.
