Comparative Analysis on the Function of Engineering Plastics For the sake of weight reduction, we choose lightweight engineering plastics.
It has medium weathering-resistant properties in four engineering plastics.
In four engineering plastics, PVC has a lowest price.
PVC rod’s threading is very rough after tapping, often used for sewage lines, drainage pipe, sheet, storage tank, artificial leather and other industrial and civil equipment.
Through comparative analysis of four engineering plastics, we chose MC-nylon to make shields and install it on the top of naked part of bolts.
