Westmoonint (HK) Corporation Limited produces several lines of powdered nitrile butadiene rubber. The PNBR 35 series is for plastic modification and includes three grades for uses like sealing strips and wire insulation. The PNBR 40 series is for friction materials and contains four grades used in brake pads and blocks. All grades are agglomerated into powder form and offer properties like oil and solvent resistance as well as toughness. The document provides specifications, characteristics, images and application instructions for each line and grade.

with PVC resin. They can mix together in certain percentage. HLN 35-3 can
reach the machinery performance requirement of abroad similar products. It’s
specially adapted in PVC resin modification and soft goods.
Application Guidance
According to different usage and different demand, the dosage of HLN 35-1 is
variable. When HLN35-1 mix with PVC resin and the PVC needs to be
plasticized, the plastication temperature should be lower than 40℃, then add
the powdered NBR HLN 35-1 and blend evenly. In the process of extrusion, we
advice the process temperature be 120-170℃; In the process of calendaring, we
advice the process temperature be 150-170℃; In the process of injection, we
advice the process temperature be 170-190℃.
