lubricant 　
lubricant function is in plastics processing in improvement resin flow property and products demolding property, anti in machine inner or mold inner viscous generate defect. generally add in plastics in or coating mold cavity surface. commonly used lubricant has acid and its salt type, long 链脂肪烃. according to lubricant function mechanism different can separation is outer lubricant and inner lubricant.

　　(1) outer lubricant: this type of lubricant and use resin versus property relatively 差, therefore commonly used in molding processing machine or mold upper, it and resin between formed lubricated 层, resin flow and products demolding, wax.

　　(2) inner lubricant: type lubricant and resin versus property good, 常掺入 resin in, reduce resin melt viscosity, improvement its flow property. hard acid ester, hard acid and other. hard acid salt type is good lubricant, also is has stabilizer.
