Xinhua Xu presentation materials commonly used in hydraulic seals

Xinhua Xu NBR nitrile hydraulic seals: suitable for petroleum-based hydraulic oil ,, glycol-based hydraulic oil, diester Department of lubricating oil, gasoline, water, silicone grease, silicone and other media use. It is currently the most widely used and lowest cost rubber seals. Does not apply to polar solvents being, such as ketones, ozone, nitro hydrocarbons, MEK and chloroform. General temperature range of -40 ~ 120 ?.

Xinhua Xu HNBR hydrogenated nitrile hydraulic seals: excellent corrosion resistance, tear and compression set properties, resistance to ozone, sunlight, weather resistance is better. There is a better abrasion resistance than nitrile rubber. Suitable for washing machines, car engine system and the use of new environmentally friendly refrigerant R134a refrigeration systems. Not recommended for use in alcohols, esters, or aromatic solution. General temperature range of -40 ~ 150 ?.

Xinhua Xu SIL silicon hydraulic seals: with excellent heat, cold, ozone resistance, resistance to atmospheric aging. It has good insulating properties. Tensile strength than ordinary rubber but not a poor oil resistance. Apply to household appliances such as electric water heaters, electric irons, microwave ovens and the like. Also it applies to all kinds of contact with the human body supplies, such as water bottles, drinking fountains and the like. Not recommended for use in most concentrated solvents, oils, concentrated acid and sodium hydroxide. General temperature range of -55 ~ 250 ?.

Xinhua Xu fluorocarbon FKM hydraulic seals: high temperature resistance than silicone rubber, has excellent weather resistance, ozone resistance and chemical resistance, cold resistance is bad. For most of the oil and solvent resistance have, especially acids, aliphatic hydrocarbons, aromatic hydrocarbons and animal and vegetable oils. Suitable for sealing demands of diesel engines, fuel systems and chemical plants. Not recommended for use in ketones, low molecular weight esters and a mixture containing nitrate. The general temperature range of -20 ~ 250 ?.

Xinhua Xu EPDM EPDM hydraulic seals: has good weather resistance, ozone resistance, water resistance and chemical resistance. Alcohols and ketones can be used to seal the high temperature steam environment may also be used. Suitable for sanitary equipment, automotive radiator and automotive brake systems. Not recommended for food use or being exposed to mineral oil. General temperature range of -55 ~ 150 ?.

Xinhua Xu NR natural hydraulic seal: has good abrasion resistance, elasticity, tensile strength and elongation. But in the air easily aging, when heated, becomes sticky, easy expansion and dissolved in mineral oil or gasoline, but not resistant to strong acid and alkali. There are suitable for use in automotive brake fluid hydroxide, ethanol and other ionic liquid. The general temperature range of -20 ~ 100 ?.

Xinhua Xu polyurethane PU hydraulic seals: Polyurethane very good mechanical properties, wear resistance, high pressure performance are far superior to other rubbers. Aging resistance, ozone resistance, oil resistance is also quite good, but the high temperature easily hydrolyzed. Generally used for high pressure resistance, wear sealed areas, such as a hydraulic cylinder. General temperature range of -45 ~ 110 ?.

Xinhua Xu PTFE PTFE hydraulic seals: excellent chemical resistance and heat resistance, can be applied in almost all cases, air, light, ozone, wide temperature range of -200 ? ~ + 250 ? low friction without sticking.
