Nitrile rubber and plastic products are polymers formed by emulsion polymerization of butadiene and acrylonitrile.
The properties of nitrile rubber and plastic products are as follows:
It has high stability for non-polar or weak polar mineral oil, animal and vegetable oil, liquid fuel, solvent, etc. Oil resistance is the characteristic of nitrile rubber. The higher the acrylonitrile content, the better.
The heat resistance is better than natural rubber products, styrene-butadiene rubber products, and neoprene products.
Good sealing performance. Second only to butyl rubber products.
Cold tolerance is poor.
Because it is an amorphous rubber and plastic product, the strength of the raw rubber is low, so it is necessary to add a reinforcing agent to improve the wear resistance, but the elasticity is reduced.
Poor dielectric properties, belonging to semiconductor rubber and plastic products
The adhesive is well-balanced in oil resistance and never deforms.
Generally with the requirements of nitrile rubber and plastic products:
The matching principle is similar to natural rubber products and styrene-butadiene rubber products. The vulcanization system of the vulcanization accelerator can also be low-sulfur, sulfur-free vulcanization system or peroxide vulcanization. Reinforcing filler must be added. The spray carbon black rubber material has good process performance, white carbon black and hard ceramic clay are mostly used for light-colored products, and the energy gathering between macromolecules is large. Therefore, the viscosity is high and the processability is poor. Adding tackifiers and softeners can reduce viscosity, improve process performance and low temperature performance of vulcanized rubber. .
Uses: Nitrile rubber and plastic products:
Mainly used in the manufacture of oil-resistant rubber products, widely used in the manufacture of seals, gaskets, etc.
