回答1:

ABS:收缩率:0.5%;用途:是最能保持产品尺寸精度的材料,一般对精度要求高的产品都用它,例如:ABS+PC是手机外壳常用的材料;
POM:收缩率:2-5%耐磨和强度都是很高的,塑料齿轮都是常用的材料。
PS:收缩率:0.5%可做透明材料,但是比较脆,但是价格很便宜。
pp:收缩率:1.6-20%;,常用在尺寸要求不高的场合,如汽车上的座椅,基本都是用这些料的。
PMMA:收缩率:0.4-0.6%又称有机玻璃,透明性能高,导光性好,但是极易刮花,汽车上的尾灯都是PMMA做的。
PE:收缩率:2-5%,常用吹塑,一般做软齿轮。
PA:收缩率:0.8-1.4%,很高的任性,强度好。
PVC:收缩率:1-2.5%;易老化,价格便宜,现在一般都是无毒PVC来做产品。
PC:收缩率:0.5-0.7%,强度很高,耐高温,价格也不菲。汽车上的前灯都是用这种材料。
MBS:收缩率:和ABS一样,透明的ABS,但是要比ABS要脆一些。
