The main products are rubber pad: silicone pads, nitrile rubber, fluoro rubber, other rubber mat.
Silicon
Has outstanding resistance to high temperature performance, -70 ºC - within a temperature range of + 260 ºC to maintain good elastic, resistant to ozone, weather aging, should make the thermo-mechanical sealing gasket. Non-toxic and can produce insulation, insulation products and medical rubber products. At the same time waterproof, fire retardant, high temperature, electrical conductivity, abrasion resistance, oil and other excellent properties, widely used in machinery, electronics, plumbing and other industries.
Nitrile rubber
NBR (Nitrile-Butadiene Rubber) is made of butadiene and acrylonitrile copolymer formed by the emulsion polymer, with its excellent oil resistance is known, also has good abrasion resistance, aging resistance and air tightness. Which are widely used in the rubber industry.
Viton
High-temperature resistance, can be -20 ºC - + 200 ºC environments, resistant to strong oxidants, oil, acid and alkali. Typically used for high temperature, high vacuum and high-pressure environment, but also suitable for oil environment, widely used in petroleum, chemical, aviation, aerospace and other sectors.
Other
Neoprene, natural rubber, EPDM rubber, acrylic rubber and other special rubber. With oil, acid, alkali, wear resistance, low temperature and other characteristics.
1 rubber gasket
NBR, SBR, CR, EPDM and other rubber gasket with oil, acid, cold and heat, anti-aging properties, can be cut into various shapes of the gasket is widely used in medicine, electronics, chemicals, antistatic, retardant, food and other industries.
Silicone rubber gasket (WMQ)
It has outstanding resistance to high temperature performance, -70 ºC - within a temperature range of + 260 ºC maintain good use bombs ...
Nitrile rubber gasket (NBR): is a butadiene and acrylonitrile copolymer formed by the emulsion polymer. Nitrile rubber gasket its excellent oil resistance (but intolerance ketones, esters and chlorinated hydrocarbons and other media) is known.
Viton gaskets
Due to a variety of excellent performance, fluorine rubber is widely used in petroleum, chemical, aviation, aerospace and other sectors.
Other rubber gasket
Neoprene, natural rubber, EPDM rubber, acrylic rubber and other special rubber.

Silicone rubber gasket (WMQ)
Silicone rubber gaskets referred to as WMQ, silicone rubber has outstanding resistance to high temperature performance, -70 ºC - maintain a good use of flexibility in the temperature range + 260 ºC, and there is resistance to ozone, weathering, etc., should be as hot Mechanical sealing gasket.
Silicone rubber gaskets technical parameters:
Silicone rubber gasket temperature: -100 ºC ~ 300 ºC
Silicone rubber gasket pressure: <3.0MPa
Silicone rubber gaskets Common Specifications: DN15 ~ DN400
Rubber gaskets rubber gasket between two stationary surfaces of the metal flanges or other connecting parts from sheet-shaped sealing rubber gaskets rubber products collectively. Available manufacture molding method, can also be cured film-making. It can be widely used in various machinery and equipment, from the gaskets, seals, cushion and so on.
Common rubber gasket washer: rubber flat washer, rubber O-rings, plastic flat washers, PTFE gasket package, asbestos rubber gaskets, metal flat washers, metal profiled washers, metal foreskin washers, wave washers, washers and other wound.
(1) rubber flat washer: deformed easily, effortlessly when pressed, but the pressure, temperature capabilities are poor, only for the low pressure, the temperature is not high places. Natural rubber has some acid and alkali resistance, temperature should not exceed 60 ºC; chloroprene rubber and ability of certain pH, temperature 80 ºC; nitrile rubber oil, available to 80 ºC; Viton good corrosion resistance, resistance temperature performance is stronger than ordinary rubber, it can be used in 150 ºC medium.
(2) The rubber gasket: cross-sectional shape is a perfect circle, there is a certain self-tightening action, better sealing effect than the flat washer, the pressing force is smaller.
3 using standard rubber gasket
Give full play to the characteristics of the various pads. ; In the use of rubber gaskets, should fully consider the following factors:
Good elasticity and recovery, to adapt pressure changes and temperature fluctuations have adequate flexibility, with the contact surface good fit;
Do not pollute the process medium;
Low temperature hardening, a small amount of shrinkage;
Processing performance, installation, pressing and convenient;
Not adhesive sealing surface, removal easy.
4 rubber gasket application
Rubber gaskets are widely used in automotive, electronics, chemicals, antistatic, flame retardant, food, machinery and equipment industries, can play the pad, sealing, cushioning effects.
