natural rubber ( NR) Nitrile rubber (, NBR) Polyurethane rubber ( AU) What is, temperature range, application scope, the price range is how much, silica gel products factory take you know.


natural rubber ( NR)

natural rubber ( NR) In order to arrange - is a 1, 4 - Polyisoprene as the main component of natural high molecular compound, its composition is 91% ~ 94% of rubber hydrocarbon ( Cis - 1, 4 - Poly (isoprene) , and the rest of the protein, fatty acid, ash content, the rubber material such as sugar. Natural rubber is the most widely used general-purpose rubber.






taken the general working temperature: - 40 ~ 70 ℃





u basic characteristics: better strong stretching, flexibility, low temperature, wear resistance and resistance to mud, oil, alcohol, glycerin,





u main use: shock absorption, cushioning, dustproof, diaphragm, sealing, packing, brake fluid products




u reference price: 1. 9 ~ 2. 40000 yuan/ton


nitrile rubber ( NBR)


and acrylonitrile butadiene nitrile rubber is made by the emulsion polymerization, nitrile rubber mainly adopts low temperature emulsion polymerization production, excellent oil resistance, high wear resistance, good heat resistance, strong adhesive relay. The disadvantages of poor low temperature resistance, ozone resistance is poor, poor insulation, slightly low elastic. Nitrile rubber is mainly used for manufacturing oil-resistant rubber products. Hereinafter referred to as NBR






taken the general working temperature: - 55 ~ 100 ℃

u basic characteristics: good oil resistance, good comprehensive performance. Painted

applications: oil and emulsion products, sealing products, dust cover, circle.

u reference price: 2. 0 ~ 2. 30000 yuan/ton


polyurethane rubber ( AU)


polyurethane rubber ( 聚氨酯橡胶) For polymerization owner chain contains more carbamate group series elastomer material, is actually a polyurethane rubber, referred to as polyurethane rubber or ammonia ester rubber ( 聚氨酯橡胶) Or polyurethane elastomer ( 聚氨酯弹性体) 。 Polymer chain besides contains carbamate group, also containing ester, ether, urea, aromatic and aliphatic chain, etc.






taken the general working temperature: - 55 ~ 100 ℃


u basic characteristics: good oil resistance, abrasion resistance, flexibility, acoustic properties.





u main use: oil resistance, abrasion resistance, sealing products, coating.





u reference price: 9. 0 ~ 11. 00000 yuan/ton





that is related to natural rubber, nitrile rubber, polyurethane rubber related to arrange, hope everybody to natural rubber, nitrile rubber, polyurethane rubber have deeper understanding, choose the silicone rubber products factory in guangdong area preferred shenzhen plant 10 old factory professional and more efficient.
