Commonly Used Sealed Rubber Ring Material And Application

  Commonly used sealed rubber ring material and application

  NBR Butyl cyanide seal

  Suitable for petroleum hydraulic oil, glycol hydraulic oil, diester lubricants, gasoline, water, silicone grease, silicone oil and other media used. rubber ring Is the most widely used, the lowest cost rubber seals. Not suitable for use in polar solvents such as ketones, ozone, nitrohydrocarbons, MEK and chloroform. General use temperature range of -40 ~ 120 ℃.

  HNBR Hydrogenated Butyl cyanide Seals

  Has excellent resistance to corrosion, tear resistance and anti-compression deformation characteristics, ozone resistance, resistance to sunlight, weather resistance is better. Better than the butyl cyanide abrasion resistance. Suitable for washing machines, automotive engine systems and the use of new environmentally friendly refrigerant R134a refrigeration system. It is not recommended for use in alcohols, esters or aromatic solutions. General use temperature range of -40 ~ 150 ℃.

  SIL silicone rubber seal

  Has excellent heat resistance, cold, ozone resistance, resistance to atmospheric aging performance. Have a good insulation performance. But the tensile strength is worse than the general rubber and not oil. Applicable to household appliances such as electric water heaters, irons, microwave ovens and so on. Also applies to a variety of contact with the human body supplies, such as water bottles, drinking fountains and so on. It is not recommended for use in most concentrated solvents, oils, concentrated acids and sodium hydroxide. General use temperature range of -55 ~ 250 ℃.

  VITON fluorine rubber seals

  High temperature resistance is better than silicone rubber, excellent weather resistance, ozone resistance and chemical resistance, cold resistance is bad. For most of the oil and solvents are resistant, especially acids, aliphatic hydrocarbons, rubber ring aromatic hydrocarbons and animal and vegetable oils. Applicable to diesel engine, fuel system and chemical plant sealing needs. It is not recommended for use in ketones, low molecular weight esters and mixtures containing nitrates. General use temperature range of -20 ~ 250 ℃.

  FLS Fluorosilicone rubber seal

  Its performance both the advantages of fluorine rubber and silicone rubber, oil, solvent resistance, fuel-resistant oil and high and low temperature resistance are good. rubber ring Resistance to oxygen-containing compounds, aromatics-containing solvents and chlorine-containing solvents. Generally used for aerospace, aerospace and military use. Not recommended for exposure to ketones and brake oil. The general use of the temperature range of -50 ~ 200 ℃.

  EPDM EPDM rubber ring

  Has a good weather resistance, ozone resistance, water resistance and chemical resistance. Can be used for alcohols and ketones, can also be used for high temperature water vapor seal. Suitable for sanitary equipment, automotive radiators and automotive brake systems. Not recommended for food use or exposed to mineral oil. General use temperature range of -55 ~ 150 ℃.

  CR neoprene ring

  Resistant to sunlight, weather resistance is particularly good. Not afraid of dichlorodifluoromethane and ammonia and other refrigerants, resistant to acid, silicone oil-resistant lubricants, but in the low point of mineral oil in the expansion of mineral oil. In the low temperature easy to crystallization, hardening. rubber ring Applicable to all kinds of contact with the atmosphere, sunlight, ozone environment and a variety of fire, chemical corrosion of the seal. It is not recommended for use in strong acids, nitrohydrocarbons, esters, chloroform and ketones. General use temperature range of -55 ~ 120 ℃.

  IIR Butyl rubber seals

  Airtightness is particularly good, heat resistance, sunshine, good ozone resistance, good insulation properties; polar solvents such as alcohol, ketone, ester, etc. have good resistance, can be exposed to animal and vegetable oils or oxides. Suitable for chemical or vacuum equipment. It is not recommended for use with petroleum solvents, kerosene or aromatics. General use temperature range of -50 ~ 110 ℃.

  ACM Acrylic rubber seal ring

  Excellent resistance to oil, high temperature, weather resistance are good, but the mechanical strength, compression deformation rate and water resistance slightly worse. Generally used in automotive transmission systems and power steering system. Does not apply to hot water, brake oil, phosphate. The general use of the temperature range of -25 ~ 170 ℃.

  NR natural rubber seals

  Has a good wear resistance, elasticity, tear strength and elongation. But easy to aging in the air, hot and viscous, mineral oil or gasoline in the easy expansion and dissolution, alkali resistance but not strong acid. rubber ring Suitable for use in automotive brake oil, ethanol and other ions with hydroxide ions. General use temperature range of -20 ~ 100 ℃.

  PU Polyurethane rubber seals

  Polyurethane rubber mechanical properties are very good, wear resistance, high pressure performance are far superior to other rubber. rubber ring Anti-aging, ozone resistance, oil resistance is also quite good, but easy to hydrolysis. Generally used for high pressure, wear-resistant seal, such as hydraulic cylinder. General use temperature range of -45 ~ 90 ℃.
