The Difference Between Dingqing Rubber And Fluorine Rubber

Basic Performance
Nitrile rubber has excellent oil resistance, second only to polysulfide rubber and fluororubber, and has excellent wear resistance and air tightness. The disadvantage of NBR is that it is not resistant to ozone, aromatic, halogenated hydrocarbons, ketones, and ester solvents, and is not suitable for use as an insulating material.

Main Uses
Nitrile rubber is mainly used in the production of oil resistant products, such as oil resistant tubing, adhesive tapes, rubber diaphragms, and large oil bags. It is commonly used in the production of various oil resistant molded products, such as O-rings, oil seals, cups, diaphragms, valves, and corrugated pipes. It is also used in the production of rubber plates and wear-resistant parts. Nitrile rubber has a very strong polarity, and generally has poor compatibility with other polymers. However, it has good compatibility with highly polar polymers such as neoprene, modified phenolic resin, and polyvinyl chloride, especially with polymers containing chlorine, and is often used in combination. In addition, in order to improve processability and usability, nitrile rubber is often used in combination with non polar rubbers such as natural rubber, styrene butadiene rubber, and cis-1,4-polybutadiene rubber. It should be pointed out that nitrile rubber is characterized by good oil resistance, and when used with other polymers (except PVC), there is a trend to reduce oil resistance.
