??Xinhua Xu Hydraulic O-ring material commonly used hydrogenated nitrile rubber HNBR

??Xinhua Xu hydrogenated nitrile rubber (Hydrogenate Nitrile) nitrile rubber by removing part of the double-stranded after hydrogenation, after hydrogenation of their heat resistance, weather resistance than nitrile rubber to improve a lot, oil and general NBR similar. General temperature range of -25 ~ 150 ?.

??Advantages:

??· Representing NBR has better abrasion resistance

??· With excellent corrosion resistance, tensile, tear and compression distortion characteristics

??· With good resistance to ozone, sunlight and other atmospheric conditions

??· Generally suitable for laundry or dishwashing detergent in

??Disadvantages:

??* Not recommended for use in alcohols, esters, or aromatic solution into. Refrigeration and air conditioning industry, widely used in environmentally friendly refrigerant R134a system seals.

??· Automobile engine system seals.

??Xinhua Xu Hydraulic O-ring material commonly used ethylene-propylene rubber EPDM

??EPDM (Ethylene propylene Rubber) by the co-polymerization of ethylene and propylene backbone substandard double-stranded, and therefore heat resistance, aging resistance, ozone resistance, stability are very good, but can not sulfur, and sulfur. To solve this problem, the EP main chain into a small amount of a third component of the double-stranded and can be sulfur and sulfur Serve EPDM, the general temperature range of -50 ~ 150 ?. Polar solvents such as alcohols, ketones, glycol lipids, and phosphorylation excellent resistance to hydraulic fluid.

??Advantages:

??· With good anti-designate and ozone resistance

??· Has excellent water resistance and resistance to chemicals

??? You can use alcohols and ketones

??· High temperature steam with good gas impermeability

??Disadvantages:

??* Not recommended for food use or being exposed to aromatic hydrogen. High temperature steam seals the environment.

??· Sanitary equipment seals or parts.

??Brake (Brake) system rubber parts.

??· Radiator (Radiator) of seals.

??Xinhua Xu Hydraulic O-ring material NBR NBR common

??NBR (Nitrile Rubber) by the polymerization of acrylonitrile and butadiene, acrylonitrile content from 18% to 50%, the higher the acrylonitrile content, resistance to petrochemical oil hydrocarbon fuel the better, but low temperature performance is poor, the general temperature range of -25 ~ 100 ?. NBR is one of the most commonly used rubber seals and O-rings present.

??Advantages:

??· With good resistance to oil, water resistance, solvent resistance and resistance to high pressure oil properties.

??· With good compression distortion, wear and elongation force.

??Disadvantages:

??· Not suitable for polar solvents being, such as ketones, ozone, nitro hydrocarbons, MEK and chloroform. · For the production of the fuel tank, oil tank and lubricating oil in the oil-based hydraulic oil, gasoline, water, silicone grease, silicone, titanium esters, glycol-based hydraulic fluid medium oil used in rubber parts, especially the sealing parts . It can be said is the most widely used and lowest cost rubber seals. Silicone rubber SI

??Xinhua Xu Hydraulic O-ring material commonly used in the silicone rubber (Silicone Rubber) main chain composed of silicon (-si-o-si) a combination. It has excellent heat resistance, cold resistance, ozone resistance, resistance to atmospheric aging. It has good electrical insulation properties. Tensile strength than ordinary rubber difference without having oil resistance. advantage:

??· After modulation formula tensile strength and tear resistance of up to up to 1500PSI 88LBS

??· Good flexibility and good compressibility

??· Neutral solvent has good resistance

??· With excellent heat resistance

??· With excellent cold resistance

??? For ozone and oxides with excellent corrosion resistance

??· Excellent electrical insulation properties

??· Insulation, good heat dissipation

??Disadvantages:

??* Not recommended for use in most concentrated solvents, oils, concentrated acid and sodium hydroxide after being diluted. · Used by the household appliances industry seals or rubber parts, such as electric kettle, electric iron, rubber parts inside the microwave oven.

??· Electronics industry seals or rubber parts, such as the phone keypad, DVD inside the cushion, cable seal joints within the like.

??· Seal with the human body in contact with all kinds of items on such as water bottles, drinking fountains and the like.

??Xinhua Xu Hydraulic O-ring material commonly used silicon fluorine rubber (Fluorinated Silicone Rubber) fluorinated silicone rubber, which generally has the advantage of performance and fluorine rubber and silicone rubber; its oil resistance, solvent resistance and fuel resistance high and low temperature are good, the general temperature of -50 ~ 200 ?.

??Advantages:

??· Suitable for special purposes, such as requiring oxygen resistant to chemicals, solvents containing aromatic hydrogen erosion and chlorinated solvents.

??Disadvantages:

??· Not recommended exposed to brake on the oil, ketones, and the corpus was · Space parts.

??Xinhua Xu Hydraulic O-ring Viton FPM

??Viton (Fluoro Carbon Rubber) molecular fluorine within the rubber, according to the fluorine content (ie monomeric building) and there are various types. Series Six fluoride fluorine rubber currently the most widely used first by the DuPont Company to "Viton" tradename market. High temperature resistance than silicone rubber, has excellent chemical resistance, resistance to most oils and solvents (ketones, esters, except), weather resistance and ozone resistance; cold is relatively poor, the general temperature range of -20 ~ 250 ?. Specially formulated to be low temperature -40 ?. advantage:

??? You can heat to 250 ?

??? For most of the oil and solvent have the ability to resist, especially all of the acids, aliphatic hydrocarbons, aromatic hydrocarbons and animal and vegetable oils

??Disadvantages:

??* Not recommended for use in ketones, low molecular weight esters and a mixture containing nitrate. * Automobiles, motorcycles, diesel engines and fuel systems.
