Imported resistant seals methane OTP has a strong R & D research and development team, self-abrasive rubber formulation research and development and design. Master Cam using design software, combined with CNC machining programs, accurate production of rubber molds. Rubber material of the formula has a fully equipped laboratory, from formulation development, characteristics of the test, rubber mixing, analysis has been operating system, with customers to develop new products. Can provide customers with rubber products, O-rings, ED rings, washer, rubber balls, heterosexual rubber, oil seals, pneumatic seals. 1. perfluorinated methane resistant O-ring standards are divided into: O-ring American Standard AS568, O-ring Japanese standard P, S, F, O-rings GB C92 2. perfluorinated rubber seals Dimensions: Diameter: from 1.0mm-50000mm (special specifications can also be customized); diameter: (0.5,0.8,1.0,1.5,1.78,1.8,2.0,2.4,2.62,2.65,3.0,3.1,3.5,3.53,3.55,4.0,4.5 , 5.0,5.3,5.33,6.0,6.99,7.0,8.0,9.0,10,12,13,14,15,20,25,30 etc.). 3. Introduction of rubber material used: nitrile rubber (NBR), Viton (VITON \ FKM), silica (SIL), EPDM rubber (EPDM). NBR color is black, the conventional hardness of 70 degrees. Fluorine rubber color is generally brown-based, conventional hardness of 75 degrees. Color is generally white transparent silicone-based, conventional hardness of 70 degrees. 4. perfluorinated excellent heat resistance rubber: high temperature properties of fluorine rubber elastomer can be said that the best present. Fluorine rubber long-term use at 220 ℃, 250 ℃ under short-term use; fluorine rubber elongation at break can be maintained at about 100%, the hardness of 90 to 95 degrees. Maintain its after aging at 350 ℃ hot air 16 hours of good elasticity, hot air aging at 400 ℃ after 110 minutes to maintain good elasticity, hot air aging at 400 ℃ after 110 minutes, spray containing carbon black, thermal black or carbon fiber rubber elongation increased by about 1 / 2-1 / 3, the intensity decreased about 1/2, still maintain good flexibility.
