Ethylene propylene Rubber (EPDM) Valve Seat for centerline butterfly valve

Ethylene propylene Rubber (EPDM)

Ethylene propylene Rubber is composed of Ethylene and propylene copolymerization, so it has good heat resistance, aging resistance, ozone resistance and stability, but weak in sulfuring. In order to solve this problem, in the main chain of the EP, importing sulfur after importing a double strand of the third component to be EPDM. Generally using temperature is - 50 ~ 150 degree. It has excellent resistance to the polarity solvent such as alcohol, ketone.

Advantages:

Good weather resistance, high temperature steam resistance, and ozone resistance, with excellent water resistance and chemical resistance, it can be used in alcohols and ketones, good permeability in gas.

Disadvantages:

Do not recommended for food use or exposure to aromatic hydrogen. Application: Sealing parts or parts of sanitary equipment in high temperature steam environment, rubber parts in a braking system, seals in a radiator.

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.
