Engineering plastics are plastics that can be used as engineering materials to replace metal in the manufacture of mechanical parts. They have excellent comprehensive properties, high rigidity, small creep, high mechanical strength, good heat resistance, good electrical insulation. They can be used in harsh chemical and physical environments for a long time and can replace metals as engineering structural materials.
The main characteristics of engineering plastics are:
(1)Compared with general plastics, it has excellent heat resistance and cold resistance, excellent mechanical properties in a wide temperature range, and is suitable for use as structural materials;
(2) Good corrosion resistance, small environmental impact, good durability;
(3) Compared with metal materials, easy to process, high production efficiency, can simplify the process and save costs;
(4) Good dimensional stability and electrical insulation;
(5) Light weight, high specific strength, outstanding anti-friction wear resistance.
