The characteristics of plastic material chart
Material name specific gravity Sturdy Impact Hot resistance Grease resistance Flame resistance Chemical resistance Elogation
PS 1.05 Good Excellent 85 ℃ Poor Fine Poor Excellent
OPS 1.05 Excellent Poor 85 ℃ Poor Fine Fine Fine
PP 0.92 Fine Good 135 ℃ Excellent Excellent Excellent Good
PVC 1.39 Good Good 60 ℃ Excellent Poor Excellent Good
A-PET 1.35 Good Good 60 ℃ Excellent Fine Excellent Good

Note:The characteristics of PET changed after heating.

In the amorphous condition it's call A-PET(Amorphous Polyethylene Terephtalate).

Crystalline PET is call C-PET.
A-PET is most common used in plastic packaging material.
