PVC lubricating modifier is a polymer with good lubricating and modifier performance which is polymerized by one or several kinds of acrylate monomer and use special adjustment of the molecular weight.  It can be used individually, but usually it is used together with other processing aids for promoting fusion of PVC resin Standard technical data Type Appearance Viscosity Volatile Contents Granularity YM-175A White free-flow powder 1.0-1.5 ≤1.3% ≥98% (25 meshes standard sieve) YM-175B 3.0-4.0 YM-175C 2.0-3.0 Lubricating performance: Recommended Application For 100phr PVC resin: Type PVC foam pipe PVC foam board PVC sheet and film PVC board PVC pipe and fittings YM-175A 0.5-2 0.5-2 0.5-1.3 YM-175B 0.5-1.7 0.5-1.7 0.5-1.2 YM-175C 0.5-1.5 0.5-1.5 0.5-1.0
