NBR Bellows
NBR Bellows Advantages:

1. Excellent Oil-proof: 
Excellent oil resistance ranks only second to polysulfide rubber, acrylate and FKM
2. High tensile strength and wear resistance.
3. Good Heat Resistance: 
Working Temperature ranging -35oC-110oC. (Short-period working: 120oC)
4. Good air tightness
5. Strong Adhesion

NBR Bellows Disadvantages:
1. Poor ozone resistance, against storage 
2. Poor electrical property
3. No resistance to aromatic solvents, halogenated hydrocarbon solvents and ketones & esters solvents
4. Low elasticity
