Wear Resistance EPDM valve seat for centerline butterfly valve

Classification of rubber

There are many varieties of rubber, and the classification methods are not uniform.

1) According to the source of materials, it can be divided into two categories: Natural Rubber and Synthetic Rubber.

2) According to its performance and use, it can be divided into two categories: Universal Rubber and Specialty Rubber Eastomer.

* Any rubber with the same or close performance as natural rubber, good physical properties and processing properties, and can be widely used in tires and other general rubber products is called general rubber.

General rubber: natural rubber (NR), styrene butadiene rubber (SBR), butadiene rubber (polybutadiene rubber, BR), isoprene rubber (polyisoprene rubber, IR)

* Any special rubber product with special properties, special for heat resistance, cold resistance, chemical corrosion resistance, oil resistance, solvent resistance, radiation resistance, etc. is called special rubber.

Special rubbers include: nitrile rubber (NBR), silicone rubber, fluoro rubber, urethane rubber, polysulfide rubber, polyacrylate rubber (UR), chloroether rubber, chlorinated polyethylene rubber (CPE), chlorosulfonated polyethylene (CSM), butadiene rubber, etc.

In fact, there is no strict boundary between general rubber and special rubber. For example, ethylene propylene rubber has the above two characteristics. Between general rubber and special rubber are: neoprene (CR), ethylene propylene rubber (EPDM), butyl rubber (IIR)

Material Quick Selection Table:

Material	Suitable Temp.	Characteristics
NBR	-35℃~100℃ Instant -40℃~125℃	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.
EPDM	-40℃~135℃ Instant -50℃~150℃	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.
CR	-35℃~100℃ Instant -40℃~125℃	Neoprene is used in media such as acids, oils, fats, butters and solvents and has good resistance to attack.
FKM	-20℃~180℃	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
