Product name:Liquid nitrile rubber 26, 33, 40 type
Liquid nitrile rubber LNBR
Liquid nitrile rubber is composed of acrylonitrile and butadiene polymerization and after high temperature pyrolysis. LNBR is a new type of low molecular liquid toughening, plasticizer and rubber softener. Can be widely used in hydrogenated nitrile rubber, nitrile rubber, acrylic rubber, fluorine rubber, chloroprene rubber and other rubber: can also be used for modified PVC, epoxy and phenolic resin, thermoplastic elastomers such as SBS/ABS industry.
Product features
And the rubber vulcanization common in sulfur or DCP curing system | To improve the processing performance |
Calendering, extruding performance improvement | Lower Mooney viscosity of mix |
Reduce the mixing rubber material heat, reducing electricity use | Cancel the plastication process rubber; shorten the plasticization time shorten rubber mixing cycle |
To reduce the deterioration of physical properties including hardness, the | In the vulcanized rubber without migration, exudation in solvent extraction, no |
To extend the service life of the product | To improve chemical resistance |
Improve heat resistant and weather resistant products | With carboxyl type rubber can adhesion increases with the metal, glass and so on. |
With the clay, white carbon black and is mechanical properties can improve rubber | |
The scope of application
LNBR and NBR, chloroprene rubber, acrylic rubber and other rubber phase solubility is good, not easy to extract in the rubber products, also can be to the operating performance of low hardness rubber products good. Widely used in rubber roller, seals, hose, seal and other products, use LNBR instead of black and white factice softener, can improve the intensity, low hardness rubber products such as process performance and product rollers elongation and resilience, but also can improve the using performance and the quality of printing roller.
LNBR can replace DOP, DBP, DOA, DOS and solid plasticized toughening materials in PVC, PVC can improve the cold resistance, heat resistance, light resistance, aging resistance, oil resistance, improve product resilience, impact resistant surface molding and product effect, but also can improve the product of plasticizer in easy migration sex. But the production of wire and cable materials, the car dashboard, car bumpers, plastic film, PVC gloves, mine conveyor belt heart, shoemaking, refrigerator seals, working shoes, brake pads and other industries.
LNBR can improve the PVC automobile sealant toughness, heat resistance, oil resistance and low temperature performance, and has good adhesiveness, good fluidity, but also can be made with strong adhesion, good elasticity and good oil resistance of adhesive and epoxy resin and phenolic resin etc..
