"NBR" Rubber Sealing used in oil system for hydraulic oil, hydraulic oil line glycol, the second-grade lubricants, petrol, water, silicone grease, silicone oil and other medias. It is the most widely used,and the minimum cost of the rubber seals. Does not used into polar solvents, such as ketones, Ozon, nitro-hydrocarbons, MEK and chloroform. Ordinary general temperature range for -40 ~ 120 ℃.
"HNBR" hydrogenated Nitrile rubber seal: Owned excellent corrosion resistance, tear resistance and deformation characteristics ,also better of ozone-resistant, resistant to sunlight, weather-resistant …properties.
Compared with NBR It has better abrasion resistance. Used in washing machines, car engines and new environment-protection refrigerant R134 a refrigeration system. Does not recommend the use in alcohol or aromatic esters liquid. The use of the general temperature range for -40 ~ 150 ℃.
"MQ" silicon rubber seal has excellent heat, cold, and ozone-resistant, resistant to aging properties in the atmosphere. There are very good insulation properties. However, tensile strenth can not catch up with other rubber and do not have oil resistance either. Used in household appliances such as electric water heaters, electric irons, microwave ovens and so on. It also applies to a variety of Daily necessities contact with the human body ,such as Kettle
, water dispenser,… Does not recommend the use in concentrated solvents, oil, chemical and sodium hydroxide .The use of the general temperature range for -55 ~ 250 ℃.
"FLS" fluorosilicone rubber seal own all the performance of both fluorine rubber and silicone ,like oil, solvent, Fuel resistant and high –low temperature resistant
properties.
Normally used in aviation, aerospace and military applications.It can not exposed in brake oil,general temperature range for -50 ~ 200 ℃.
<EPDM >EPDM seal: a good weather resistance, ozone resistance, water resistance and chemical resistance. Can be used in alcohols and ketones , Can also be used to heat water vapor seal.Also can be chosed in sanitary equipment, automotive radiator and automotive braking systems. Is not recommended for food
Use or exposure to mineral oils .General temperature range for -55 ~ 150 ℃.
"CR" chloroprene rubber seal: the sun-resistant, weather-resistant properties are particularly good. it will be easy crystallized and sclerosised When the low temperature. Applicable to all kinds of contact with the atmosphere, the sun, Ozone environment and a variety of fire, corrosion-resistant chemical aspects of the seal. Does not recommend the use in strong acid, hydrocarbons nitro, esters, ketones and chloroform chemicals . General used in -55 ~ 120 ℃.
ACM "acrylic rubber seal: For oil has strong resistance, high temperature and weather resistance are very good, but the mechanical strength, deformation rate and water resistance can not match with others. Widely used for transmission and power steering systems. Does not apply to hot water, brake oil, phosphates are.The use of the temperature range of -25 ~ 170 ℃. |
