The acrylic lotion supplier will show you the difference between powdered nitrile rubber and liquid nitrile rubber.

(1) Different basic characteristics

There are four basic characteristics of powdered nitrile rubber: 

① rubber mixing does not use large machinery, thus saving energy; 

② Automatic and continuous rubber mixing, saving manpower;

 ③ The manufacturing cost of powdered rubber is high; 

④ Due to the addition of inorganic fillers, the scope of use is limited. This product is mainly used for resin mixing, can be used as plasticizer of PVC, and can be used as sole with PVC, suitable for cable sheath, gasket, textile industry and adhesive, etc.

There are three basic characteristics of liquid nitrile rubber: 

① it is a viscous liquid at room temperature, so it can be painted, infiltrated, injected, etc.; 

② Because there are two terminal functional groups, chain extension and crosslinking reaction can be carried out; 

③ It is compatible with other polymers due to its acrylonitrile content.

(2) Different uses

The liquid nitrile rubber produced by the powder nitrile rubber supplier is mainly used as an adhesive to prepare various conductive adhesives, thermal conductive adhesives, turbine blade coatings, plasticizers, etc., and can be grafted and copolymerized with the antioxidant butyl to form a polymer antioxidant, which is not easy to be extracted from solvents, etc., which not only improves the anti-aging performance, but also improves the oil resistance. In addition, it is widely used as bonding, sealing and spraying materials, and has good effect as toughening agent for epoxy resin.

It can be used as automobile valve cover, motor caulking material, adhesive for wood products, diaphragm for gas meter parts, adhesive for piezoelectric ceramic buzzer components, high pressure and low temperature resistant insulation potting material, and pouring oil resistant rubber products, and can also be used to make modified epoxy resin with water resistance.

Powdered nitrile rubber is applicable to seals, sealing strips and sealing rings, which significantly improves physical properties such as tensile strength, tear strength, brittleness temperature and compression deformation, especially oil resistance.
