Jun 05, 2017

Five, FLS fluorine silicone rubber sealing ring

Its properties are both fluorine rubber and silicone rubber advantages, oil resistance, solvent resistance, fuel resistance and high temperature resistance are excellent. Compounds capable of resisting oxygen containing compounds, solvents containing aromatic hydrocarbons, and solvent containing chlorine. The general use temperature range is -50~200 degrees centigrade.

Six, EPDM three yuan EPDM sealing ring has a good weather resistance, ozone resistance, water resistance and chemical resistance. It can be used in alcohols and ketones, and can also be used in high temperature steam environment. Generally use temperature range of -55~150 degrees centigrade.

Seven, CR neoprene sealing ring, sun resistance, weather resistance performance is particularly good. Not afraid of two chloro two methyl fluoride and ammonia refrigerant, resistant to acid resistance, grease lubricating oil, but the expansion in low aniline point of mineral oil in large quantity. It is easy to crystallize and harden at low temperature. Applicable to a variety of exposure to the atmosphere, sunlight, ozone and a variety of combustion resistance, chemical corrosion sealing links. Not recommended for use in chemicals such as strong acids, nitro hydrocarbons, esters, chloroform, and ketones. The general use temperature range is -55~120 degrees centigrade.

Eight, IIR butyl rubber seal tightness is particularly good, sunlight, heat resistance, ozone resistance, good insulation performance; have good resistance to polar solvents such as alcohols, ketones, esters, etc., can be exposed to animal and vegetable oils or oxides. Suitable for chemical resistance or vacuum equipment. Not recommended for use in conjunction with petroleum solvents, kerosene or aromatics. The general use temperature range is -50~110 degrees centigrade.

Nine, ACM acrylic rubber sealing ring for oil products have excellent resistance, high temperature and weather resistance are good, but mechanical strength, compression deformation rate and water resistance is slightly worse. Generally used in automotive transmission systems and power steering systems. Not suitable for hot water, brake fluid, phosphate ester. The general use temperature range is -25~170 degrees centigrade.

Ten, NR natural rubber sealing ring

Rubber has good abrasion resistance, elasticity, tensile strength and elongation. But easy to aging in the air, when the heat becomes sticky, in mineral oil or gasoline expansion and dissolution, alkali resistance, but not strong acid. Suitable for brake oil, such as ethanol with hydroxyl ion liquid used in the automobile. The general use temperature range is -20~100 degrees centigrade.

Eleven, PU polyurethane rubber sealing ring, polyurethane rubber mechanical performance is very good, wear-resisting, high pressure resistance performance is far superior to other rubber. Aging resistance, ozone resistance, oil resistance is also very good, but high temperature hydrolysis. Generally used for high pressure, wear and tear sealing links. The general use temperature range is -45~90 degrees centigrade.
