Xin Huaxu seal material description

 

Silicone hydraulic seals: with excellent heat resistance, cold resistance, ozone resistance, resistance to atmospheric aging properties. Has a good insulation properties. But the tensile strength than the average rubber and not with oil resistance. Applicable to household appliances such as electric water heaters, electric 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 ?.

Fluorocarbon rubber seals: high temperature resistance is better than silicone rubber, has 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, aromatic hydrocarbons and animal and vegetable oils. Suitable for diesel engine, fuel system and chemical plant sealing needs. Not recommended for use in ketones, low molecular weight esters and mixtures containing nitric acid. General use temperature range of -20 ~ 250 ?.

Fluorine silicon hydraulic seal: the performance of both fluorine rubber and silicone rubber advantages, oil, solvent resistance, resistance to fuel oil and high temperature resistance are good. Resistant to oxygen-containing compounds, aromatic hydrocarbons containing solvents and solvents containing chlorine erosion. Generally used for aviation, aerospace and military purposes. Exposure to ketones and brake fluids is not recommended. General use temperature range of -50 ~ 200 ?.

EPDM hydraulic seal: 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 environment of the seal. For bathroom equipment, car radiators and automotive brake system. Not recommended for food use or exposure to mineral oil. The general use temperature range is -55 ~ 150 ?.

Chloroprene hydraulic seals: resistant to sunlight, weather resistance is particularly good. Not afraid of dichlorodifluoromethane and ammonia refrigerants, resistant to acid, fat-resistant lubricants, but in the aniline point of low expansion of the mineral oil. At low temperature easy to crystallization, hardening. Applicable to all kinds of contact with the atmosphere, sunlight, ozone and a variety of fire-resistant, chemical-resistant seal links. Not recommended for use in strong acids, nitrohydrocarbons, esters, chloroform and ketones among the chemicals. General use temperature range of -55 ~ 120 ?.

Hydrogenated nitrile rubber seals + Article: has excellent corrosion resistance, tear resistance and compression deformation characteristics, ozone resistance, resistance to sunlight, weather resistance is better. Better than the nitrile rubber abrasion resistance. It is suitable for use in washing machines, automobile engine systems and refrigeration systems using the new environmentally friendly refrigerant R134a. Is not recommended for use in alcohols, esters or aromatic solution. General use temperature range of -40 ~ 150 ?.

Butyl cyanide hydraulic seals are suitable for use in petroleum-based hydraulic fluids, glycol-based hydraulic oils, diester lubricants, gasoline, water, silicone greases, silicone fluids and the like. Is the most widely used, the lowest cost of rubber seals. Not suitable for polar solvents, such as ketones, ozone, nitrohydrocarbons, MEK and chloroform. General use temperature range of -40 ~ 120 ?.

Butyl hydraulic seals: airtight particularly good, heat, sunlight, ozone resistance, good insulation properties; for polar solvents such as alcohols, ketones, esters have good resistance to exposure to animal and vegetable oils Or an oxidizable compound. 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 ?.

Natural hydraulic seals: with good wear resistance, elasticity, tear strength and elongation. But easy to aging in the air, the case of heat become sticky, mineral oil or gasoline in the easy expansion and dissolution, alkali resistance but not strong acid. Suitable for automotive brake oil, ethanol and other ions with hydroxyl ions in the use. General use temperature range is -20 ~ 100 ?.
