            從頭學材料——PS 聚苯乙烯

            動態 2018.12.05

            聚苯乙烯雖然擁有可媲美水晶的凈度,但卻不是一個會讓人聯想到高品質的材料。想想巧克力盒的塑料淺盤和Airfix的玩具模型,這項塑料給我們的印象就跟PVC 和 PE 差不多。主要特性· 多樣性制成 · 天然狀態易裂· 凈度優 · 剛度佳· 收縮率底 · 可回收
            同一家族的成員縮寫:HIPS 、EPS、ABS、SAN、SMA生產作為一種通用塑料,他可以用所有的標準技術進行加工,包括射出成型、熱成型、泡沫成型等。純形狀非讓易碎,混合后可增加強度,但會降低光學凈度。永續性
            聚苯乙烯是最具回收性的塑料之一,卓越鉛筆公司的增值回收數量就是很好的證明。在回收標志里它的識別號碼是6號。

            一般用途
            由于價格低廉和加工容易,聚苯乙烯的用途非常廣泛,例如:一次性餐具、杯盤和食品包裝。其他領域還有CD盒、BIC原子筆和剃刀、冰箱抽屜、利用其易碎性的Airfix玩具模型。發泡聚苯乙烯則是作為包裝盒隔熱材料使用。
