氢化丁晴橡胶(HNBR) 丁二烯和丙烯晴的共聚体。
它是通过全部或部分氢化NBR的丁二烯中的双键而得到的。其特点是机械强度和耐磨性高,用过氧化物交联时耐热性比NBR好,其他性能与丁晴橡胶一样。缺点是价格较高。使用温度范围:约-30℃~+150℃。
主要用于耐油、耐高温的密封制品。
Hydrogenated nitrile rubber (HNBR) of butadiene and acrylonitrile copolymer.
It is through full or partial hydrogenation of the double bond of butadiene NBR while to get. Characterized by high mechanical strength and wear resistance, cross-linked with peroxide when good heat resistance than NBR, NBR other properties and the same. The disadvantage is higher prices. Operating temperature range: about -30 ℃ ~ +150 ℃.
Mainly used for oil, high temperature sealing products.
  硅橡胶(Q) 为主链含有硅、氧原子的特种橡胶,其中起主要作用的是硅元素。
其主要特点是既耐高温(最高300℃)又耐低温(最低-100℃),是目前最好扥艾寒、耐高温橡胶;同时电绝缘性优良,对热氧化和臭氧的稳定性很高,化学惰性大。缺点是机械强度较低,耐油、耐溶剂和耐酸碱性差,较难硫化,价格较贵。使用温度:-60℃~+200℃。
主要用于制作耐高低温制品(胶管、密封件等)、耐高温电线电缆绝缘层,由于其无毒无味,还用于食品及医疗工业。
Silicone rubber (Q)-based chain containing silicon and oxygen atoms of special rubber, which play a major role in the silicon.
Its main characteristic is both high temperature (up to 300 ℃) and low temperature (minimum -100 ℃), Ai is the best Alto, cold, high temperature rubber; both excellent electrical insulation on the thermal stability of high oxidation and ozone chemical inert. The disadvantage is lower mechanical strength, oil, solvent and acid poor, difficult to cure more expensive. Temperature: -60 ℃ ~ +200 ℃.
Mainly for the production of high and low temperature products (hoses, seals, etc.), high temperature wire and cable insulation, because of its non-toxic and tasteless, but also for food and medical industries
   氟橡胶(FPM) 是由含氟单体共聚而成的有机弹性体。
其特点耐温高可达300℃,耐酸碱,耐油性是耐油橡胶中最好的,抗辐射、耐高真空性能好;电绝缘性、机械性能、耐化学腐蚀性、耐臭氧、耐大气老化性均优良。缺点是加工性差,价格昂贵耐寒性差,弹性透气性较低。使用温度范围:-20℃~+200℃。
主要用于国防工业制造飞机、火箭上的耐真空、耐高温、耐化学腐蚀的密封材料、胶管或其他零件及汽车工业。
ction of high and low temperature products (hoses, seals, etc.), high temperature wire and cable insulation, because of its non-toxic and tasteless, but also for food and medical industries
Viton (FPM) is formed by the monomer of organic fluorine-containing elastomers.
Characterized by high temperature up to 300 ℃, acid and alkali, oil is the oil and rubber in the best radiation resistance, high vacuum performance; electrical insulation, mechanical properties, chemical resistance, ozone resistance, resistance to atmospheric aging resistance are excellent. The disadvantage is poor processing, poor cold tolerance expensive, flexible low permeability. Operating temperature range: -20 ℃ ~ +200 ℃.
Mainly used in defense industry manufacturing aircraft, rocket-resistant vacuum, high temperature resistance, chemical corrosion sealing materials, hoses or other parts and the automotive industry.
