Product Description Product DescriptionIt can modify thermoplastic materials such as PVC, epoxy, and phenolic resins. Due to its polarity, it exhibits excellent compatibility with PVC, widely used in the footwear industry, hoses, wires and cables, conveyor belts, profiles, friction materials, and other resin-modified materials, it increases the elasticity, impact toughness, extraction resistance, oil resistance low-temperature brittleness resistance, and other properties of the product. When powdered nitrile is used instead of block nitrile, it provides a better degree of mixing and can reduce the mixing process. Using powdered nitrile in the rubber product industry can reduce energy consumption and increase production capacity by 50% compared to the production of block nitrile rubber.Powder NBRPowdered NBR is usually available in particle sizes of 0.3-0.6mm, has good flowability, and has the basic properties of rubber. Regarding reprocessing, the cutting process is omitted compared to block rubber, enabling dry powder mixing. In addition, no preheating is required for processing, which results in good dispersion and shortens the mixing time. It can also be mixed directly with compounding agents for extrusion or injection molding, saving energy and reducing heat build-up during processing to reduce scorching. The product does not agglomerate during transport.Product ParametersTypeP830EP830TP540EP650EP850TP840EMooneyviscosityML(1+4)100oC 60±560±575±564±563±562±5Acrylonitrilecontent (ACN%) 20~2520~2520~2527~2920~2520~25Isolation agent CPEPVCLight calciumcarbonatePVCPVCLight calcium carbonateCrosslinking typenon-crosslinkednon-crosslinkednon-crosslinkednon-crosslinkednon-crosslinkedCrosslinking can be carried out during high-temperature processing with crosslinking agentsMesh 50 mesh sieving rate ≥ 98%50 mesh sieving rate ≥ 98%50 mesh sieving rate ≥ 98%50 mesh sieving rate ≥ 98%50 mesh sieving rate ≥ 98%50 mesh sieving rate ≥ 98%Application scope and characteristic standardsUsed for PVCmodificationHigh transparency,low temperature resistant soft PVC productsUsed for PVC modification,convevorbelt, resin modificationUsed for PVC high oil resistantproductsTransparent PVC productsUsed in the friction material brake pad industryStandard Compliant with EU ROHS+18P standards and REACH regulations Application Range:The main function and effect as following:1.Modify phenolic resin,increase its flexibility and improve the frictional properties,thereby obtain high and stable coefficient of friction.2.Add powdered NBR in friction materials can make rubber powder particles uniformly distributed in the mixed materials,thereby reduce the abrasion of the friction material.3.Powdered NBR has good toughening effect as the elastomer,can increase the impact strength of friction materials. 4.PNBR can reduce products hardness and braking noise to improve braking comfort.Applications:It's used for friction material such as disk,drum brake pad,clutch heading,grinding wheel,abrasives,train brake shoe and so on. Powdered Nitrile Butadiene Rubber(PNBR) has good bonding effect,can increase the adhesive ability of friction material system.It can improve the impact strength of pressure embryo,and provide product flexibility.So PNBR is the ideal friction material modifier,mainly used for brake pad,train brake shoe,motorcycle and other fields.
