Analysis of superior properties of powdered nitrile rubber

Powdered nitrile rubber is a kind of rubber with certain elasticity and good resistance to Shantou, ozone and abrasion.

Nitrile rubber latex is crushed after spray drying or freezing, and the particle size can be about a f; t,}。 Rib rubber is also prepared by co-precipitation of latex and isolating agent (such as organic compound and fine powder polyethylene).

Nitrile rubber can be used together with natural rubber, styrene-butadiene rubber, cis-polybutadiene rubber, ethylene-propylene rubber, chloroprene rubber, chlorinated butyl rubber, chlorosulfonated polyethylene rubber, fluororubber and other rubber and PVC, phenolic resin and other resins to improve processing and use functions and reduce costs. What are the performance advantages of powdered nitrile rubber? The manufacturer of powdered nitrile rubber will show you next.

(1) Mineral oil, animal and vegetable oil, liquid fuel and solvent have high stability due to the presence of nitrile group. Oil resistance is its major specialty. The higher the content of acrylonitrile, the better the oil resistance.

(2) The heat resistance is better than that of natural rubber, styrene-butadiene rubber and neoprene, and it can be used for a long time under 1z0c in the air.

(3) The air tightness is good, second only to butyl rubber.

(4) Cold resistance and low temperature resistance are poor. The higher the content of acrylonitrile, the worse the cold resistance.

(5) Because of the low strength of the uncoated rubber, it is necessary to add a reinforcing agent. Increasing the amount of combined acrylonitrile will help to increase the strength and wear resistance, but the elasticity will decrease.

(6) Nitrile rubber has a poor dielectric function, which is attributed to semiconductor rubber.

(7) The balance between oil resistance and deformation of rubber compound, and the balance between oil resistance and electrical function is important.

Powdered nitrile rubber is mainly used to make oil-resistant rubber products, and is widely used to make molded products and press-out products such as seals, gaskets, washers, various rubber rollers, oil-resistant rubber tubes, industrial supplies and adhesives, etc.
