NBR EPDM Rubber Bellow Wear Resistant Rubber Expansion Bellows

Rubber bellows are can be used to fix alignment. They also absorb sound and vibration. They are also called as shock absorbers. They help in absorbing movement of engines, tanks, pipelines, turbines, machines equipment etc.

Features:

• Extremely Flexible
• Economical
• Used to protect Machine and its Parts
• Sturdy
• They can be manufactured in different materials

EPDM:Ethylene-Propylene / EPDM O-Rings: Ethylene propylene rubber is an elastomer prepared from ethylene and propylene monomers (ethylene propylene copolymer). Our stock O-Ring compoundare made with an amount of a third (diene) monomer (ethylene propylene diene terpolymers). Ethylenepropylene-diene rubber (EPDM) produced using a third monomer and is particularly useful when sealing phosphate-ester hydraulic fluids and in brake systems that use fluids having a glycol base. EPDM has outstanding resistance to heat, water and steam, alkali, mild acidic and oxygenated solvents, ozone, and sunlight; but it is not recommended for gasoline, petroleum oil and grease, and hydrocarbon environments. This popular rubber compound is usually the first choice for low torque drive belt applications.

Applications: Cold and Hot Water, Steam up to 300°F (149°C), Various Water / Municipalities Applications, Household Appliances, Glycol based brake fluids up to 300°F (149°C), Many organic and inorganic acid, Cleaning agents, soda alkali, potassium alkali, Phosphate-ester based hydraulic fluids (HFD-R), Silicone Oil, Silicone Grease, Many polar solvents (alcohols, ketones, esters), Ozone resistant, aging resistant, weather resistant, Outdoor Applications and Electrical Insulators..

Avoid: Mineral oil products (oils, greases and fuels), Solvents, Aromatic Hydrocarbons, Liquefied Petroleum Gas (LPG), Lubricating Oils, Petroleum Base Gasoline

NBR is mainly used to manufacture oil resistant rubber products. Acrylonitrile content in nitrile butadiene rubber (%) has 42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30, 18 ~ 24 and other five kinds. The more acrylonitrile content, the better oil resistance, but cold resistance is decreased. It can be used in 120℃ air or 150℃ oil for a long time. In addition, it also has good water resistance, air tightness and excellent bonding properties. It is widely used to produce all kinds of oil-resistant rubber products, a variety of oil-resistant gaskets, gaskets, bushing, flexible packaging, flexible hose, printing and dyeing roller, cable adhesive materials, etc. It has become an indispensable elastic material in automobile, aviation, petroleum, photocopying and other industries.
