H series lubricant is polyol fatty acid ester, divided into internal lubricant and external lubricant. PVC lubricant can improve the flow of resin and mold release of products in plastic processing. External lubricant: External lubricant is less compatible with the resin; its role is to form a lubricant layer between the molding machine or mold and the resin to facilitate the flow of the resin and product demolding. Internal lubricant: The internal lubricant has good compatibility with the resin and can reduce the melt viscosity of the resin and improve its fluidity. It has good transparency and dispersion, H-60 is both good lubricant and effective stabilizer.
