Product Details

Custom EPDM NBR FKM Rubber Bellows Silicone Rubber Products
 
Product Description
 
Rubber bellows (also known as expansion joints) are used to protect moving mechanical parts from dust and humidity. The concertinaed sides allow the rubber bellow to expand and contract whilst maintaining a permanent seal.

To suit specific industrial application, different types of rubber bellows are available in the market including single ended rubber bellows, double ended rubber bellows, rubber bellows with ribs and rubber bellows without ribs.

Materials Used in Rubber Bellows:

Depending upon the end use requirements, rubber bellows are manufactured using various synthetic polymers like:

• SBR

• Neoprene

• HNBR

• Ethylene Propylene Diene Monomer (EPM, EPDM), etc .

 

MaterialEPDM(Ethylene propylene Rubber)
Advantage1.Excellent heat resistance
2.Excellent ozone properties
3.Excellent aging property
4.Excellent stability
5.Excellent resistance to polar solvents, such as alcohol, ketone, ester and other phosphate ester hydraulic oil
Disadvantage 
Temperature-54℃~150℃
ApplicationMainly used in automobile, aviation, printing, textile and machinery manufacturing industry, due to the development of NBR modified varieties, expanded the application prospect of nitrile rubber, summed up the main play: manufacturing of spare Shanshan box, fuel tubing, oil cloth, oil seal, oil pipe, oil resistant rubber parts with contact with Shanshan products, etc..

 

MaterialNBR(Nitrile Rubber ( Buna ))
Advantage1.Excellent oil resistance
2.Hydrolytic resistance
3.Excellent wear resistance
4.Good air tightness
5.Excellent antistatic properties
6.Resistant to alcohol
Disadvantage1.Poor cold resistance
2.Not resistant to ozone
Temperature54℃~135℃
ApplicationNBR is mainly used to manufacture oil resistant rubber products

 

MaterialFPM / FKM(Fluoro Carbon Rubber)
Advantage1.Excellent High Temperature Resistance
2.Excellent Abrasion-Resistance
3.Excellent Oil Resistance
4.Excellent Weathering Resistance
5.Excellent Ozone Resistance
6.Good Water Resistance
Disadvantage1.Poor Low Temperature Resistance
Temperature-20℃~260℃
ApplicationWidely used in automotive, aerospace, chemical plant sealing parts

 

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.
