polyurethane (PU) valve seat for wafer / centerline butterfly valve 1''-54''
Polyurethane rubber (PU)
1. Basic characteristics:
1.1 High mechanical strength, can get a wide range of performance
1.2 Good heat aging resistance, ozone resistance and chemical
1.3 Compared with polyether urethane rubber, it has high mechanical
strength. However, the cold resistance is poor.
1.4 Other properties are almost the same as polyether urethane
2. Scope of application: Widely used in the automotive industry,
machinery industry, electrical and instrumentation industry,
leather and footwear industry, medical and sports fields due to its
excellent performance. Manufacture of various components, soles and
heels, solid tires, conveyor belts, ducts, screens and screens,
bushings and bushings, pump and impeller coatings, rubber rollers,
gaskets, oil seals, sports shoes, field cable protection Sets and
sponge foam products, etc.

Material Quick Selection Table:
|Nitrile rubber has good self-expanding properties, abrasion
resistance and hydrocarbon-resistant properties. It can be used as
a general material for water, vacuum, acid, salt, alkali, grease,
oil, butter, hydraulic oil, glycol, etc. Can not be used in places
such as acetone, ketone, nitrate, and fluorinated hydrocarbons.|
Ethylene-propylene rubber is a good general-purpose synthetic
rubber that can be used in hot water systems, beverages, dairy
products, ketones, alcohols, nitrates, and glycerin, but not in
hydrocarbon-based oils, inorganics, or solvents.
|Neoprene is used in media such as acids, oils, fats, butters and
solvents and has good resistance to attack.|
|Fluororubber is a good hydrocarbon-resistant base oil, fluorinated
hydrocarbon rubber for oily gas and other petroleum products. It is
suitable for water, oil, air, acid and other media, but it can not
be used for steam, hot water or thicker than 82 °C. Alkali system.|
|SR||-70℃~200℃||Silicone rubber is resistant to high temperature, low temperature
and stable chemical properties, and is widely used in industries
such as strong acid, weak alkali and food.|
Special materials: carboxylated nitrile rubber, hydrogenated
nitrile rubber, corrosion-resistant ethylene-propylene rubber,
steam-resistant fluoroelastomer, chlorosulfonated polyethylene
