1 rubber mat

 

The main products of rubber pads are: silicone pads, nitrile rubber pads, fluorine rubber pads, and other rubber pads.

 

1.1 Silicone rubber

 

Has outstanding high and low temperature resistance, maintains good elasticity in the temperature range of -70 ℃-+260 ℃, resistant to ozone and weather aging, suitable for sealing gaskets in thermomechanics. Non-toxic can be used to make heat insulation, insulation products and medical rubber products. At the same time, it has excellent properties such as waterproof, flame retardant, high temperature resistance, electrical conductivity, wear resistance, oil resistance, etc. It is widely used in machinery, electronics, plumbing and other industries. The silicone pads produced by our company meet the EU environmental protection standards and EU food grade standards.

 

1.2 Nitrile rubber

 

NBR (Nitrile-Butadiene Rubber) is a polymer composed of butadiene and acrylonitrile copolymerized by emulsion. It is known for its excellent oil resistance, but also has good wear resistance, aging resistance and air tightness. Therefore, it is widely used in the rubber industry.

 

1.3 Fluorine rubber

 

Has high temperature resistance, can be used in -20 ℃-+200 ℃ environment, resistant to strong oxidants, oil, acid and alkali. Usually used in high temperature, high vacuum and high pressure environment, also suitable for oil environment, widely used in petroleum, chemical, aviation, aerospace and other departments.

 

1.4 Other

 

Neoprene, natural rubber, EPDM, acrylic rubber and other special rubbers. It has the characteristics of oil resistance, acid, alkali, wear resistance, high and low temperature resistance.

 

2 Rubber gasket

 

NBR, SBR, CR, EPDM ... Rubber gaskets have the properties of oil resistance, acid and alkali resistance, cold heat resistance, aging resistance, etc., and can be directly cut into various shapes of sealing gaskets. Static electricity, flame retardant, food and other industries.

 

2.1 Silicone rubber gasket (WMQ)

 

Has outstanding resistance to high and low temperature performance, and maintains good use in the temperature range of -70 ℃-+260 ℃ ...

 

NBR: It is a polymer made of butadiene and acrylonitrile by emulsion copolymerization. Nitrile rubber gasket is known for its excellent oil resistance (but not resistant to media such as ketones, esters and chlorinated hydrocarbons), but also has good wear resistance, aging resistance and air tightness, so it is in the rubber industry Wide range of applications.

 

2.2 Fluorine rubber gasket

 

Has high temperature resistance, can be used in -20 ℃-+200 ℃ environment, resistant to strong oxidants, oil, acid and alkali. Usually used in high temperature, high vacuum and high pressure environment, also suitable for oil environment. Due to various excellent properties, fluororubber is widely used in petroleum, chemical, aviation, aerospace and other sectors.

 

2.3 Other rubber gaskets

 

Neoprene, natural rubber, EPDM, acrylic rubber and other special rubbers.

Silicone rubber gasket (WMQ)

 

Silicone rubber gasket is abbreviated as WMQ. Silicone rubber has outstanding high and low temperature resistance. It maintains good elasticity in the temperature range of -70 ℃-+ 260 ℃, and has the advantages of ozone resistance and weather resistance. Sealing gasket in machinery. Because there is no any toxicity, it can produce heat insulation, insulation products and medical rubber products. At the same time, it has many excellent properties such as waterproof, flame retardant, high temperature resistance, electrical conductivity, wear resistance, oil resistance, etc. It is widely used in machinery, electronics, plumbing and other industries.
