    polyethylene wax more is white or micro block 状, sheet/slice or powder 粒状, molecular weight generally in 1000-4000, formed is wax resin, therefore by is polyethylene wax, low separation polyethylene wax chemical stability property good, white, 无味, its chemical formed, value, electrical property can, density and other and wax versus 似. solvent water, in room temperature lower micro solvent acid, alkali, 松节油, 汽油, and 二甲苯, in 80℃ above solvent 于甲苯, 二甲苯, 松节油 and material 油, and large more polymer 互容, property most good is and wax, its is wax, that wax, wax and other, polyethylene wax soft products melting point in 90℃ left right, hard products in 110℃ left right.

        polyvinyl chloride (PVC) resin （简称PVC） in processing molding 时, is for hot unstable, therefore in molding processing 时, need add heat stabilized agent molding use lubricant, lubricant can anti resin in plastics products processing machine internal or local hot 而引起 resin separation understanding, make resin easy molding, usually lubricant has below/following types type type: decrease/reduce PVC separation 子间摩 scratch and improvement internal flow property is internal lubricant; anti resin viscous in price molding inner external lubricant and upper types function inner outer use lubricant.

pvc

       1. external lubricant excellent 良

        in calendering molding 时, to anti viscous 附轧辊 效果; in pressure molding and injection molding, molding 时, has anti viscous screw and mold, improve/increase demolding 效果, improvement plastics products property.

       2. has internal lubricated 效果        

        especially is chlorine polyethylene wax, due to its separation in tool has property 基团, can to internal lubricated 效果.

        3. effect/influence transparent property

        polyethylene wax add in PVC in, use amount is 0.3%时 不 effect/influence PVC transparent property, use high density polyethylene wax （ molecular weight 2000-4000） or chlorine polyethylene wax low acid value type （ acid value 1.0 left right, molecular weight 4000 left right ）, for PVC transparent property effect/influence small.

        4. dispersion property good

        especially is is powder polyethylene wax, more easy and PVC uniform combined, uniform dispersion in PVC products in.

        5. heat stabilized property good, 不起霜, demolding.

        polyethylene wax add in PVC in generate 初期染 color phenomenon, therefore PVC heat stabilized property very good; in molding surface 也不会出现起霜 phenomenon, in 轧辊面 and 模塑面不会出现 demolding phenomenon.

        青岛赛诺 production PVC use polyethylene wax tool has below/following advantages: polyethylene wax in PVC products processing production in, main/primary is as is inner outer lubricant.

        1. products surface gloss more 佳

        2. polyethylene wax and polymer has good versus property, can reduce separation inner polymer versus property relatively 差, improvement plastics melt inner scratch hot and melt flow property

        3. add amount less, lubricated obvious

        4. polyethylene wax add in PVC in effect/influence PVC transparent property
