Comparison between Jiangmen engineering plastics and steel

2020-11-29 1628

The advantages of engineering plastics are not only that, but also many other features that cannot be achieved by other steels, such as:


1. Chemical resistance: the chemical corrosion resistance of engineering plastics is much better than that of metals;


2. Light specific gravity: low density is a major advantage of plastics, which reduces both cost and weight;

3. Self lubrication: it is not used as lubrication protection, which can reduce the protection cost and reduce the accident rate;


In addition, there are many characteristics such as resistance and high temperature resistance, which are good materials for replacing steel.
