常用塑料缩水率表塑料的收缩率是指塑料制件在成型温度下尺寸与从模具中取出冷却至室温后尺寸之差的百分比。它反映的是塑料制件从模具中取出冷却后尺寸缩减的程度。影响塑料收缩率的因素有：塑料品种、成型条件、模具结构等。不同的高分子材料的收缩率各不相同。其次塑料的收缩率还与塑件的形状、内部结构的复杂程度、是否有嵌件等有很大的关系。代号ABS名称缩水率（丙烯腈/丁二烯/苯乙烯）共聚物(苯乙烯-丙烯腈)共聚物聚碳酸酯（丙烯腈/丁二烯/苯乙烯）共聚物+（苯乙烯-丙烯腈)共聚物聚氯乙烯ABS（加玻纤）SANPCABS+SANPVC0.50%（0.4~0.7%）0.2~0.4%0.40%0.60%0.40%2.00%PVC（硬质）PVC（软质）POMPPPMMAHDPELDPEGPPSPBTPETPA6PA66PA1010EVA聚甲醛聚丙烯聚甲基丙烯酸甲酯高密度聚乙烯(低压)低密度聚乙烯(高压)普通聚苯乙烯聚对苯二甲酸丁二酯聚对苯二甲酸乙二酯尼龙6尼龙66尼龙1010（乙烯-醋酸乙烯）共聚物0.4~0.7%1.0~5.0%1.70%（1.8~3.0%）1.60%（1.2~2.5%）0.50%2.00%2.00%0.50%1.70%1.70%1.20%1.50%1.50%2.00%(1.2~2.0%)PEPSPCPMMAPPOPPSPEEK1.2~1.28%0.3~0.6%0.6~0.8%0.3~0.7%0.5~0.9%1%1.2%代号ABS+PCPA+25%GFPBT+15%GFPBT+20%GF常用塑料原料之缩水率化学名称缩水率(%0)密度(g/cm3(4-5)158(7-8)1.251.2(1.5-1.6)(1.5-1.6)备注
