The difference between plastic products PP and PC is: different nature, different uses, different characteristics.
One, the nature of different
1, PP: polypropylene is a polymer made of propylene polymerization reaction.
2, PC: the molecular chain contains carbonate-based polymer.
Two, different uses
1, PP: widely used in clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, conveying pipelines, chemical containers, and other production, but also for food, pharmaceutical packaging.
2, PC: PC can be used as door and window glass, PC laminate is widely used in banks, embassies, detention centers and public **** place of protection window, for aircraft hatch, lighting equipment, industrial safety stalls and bulletproof glass.
Three, different characteristics
1, PP: chemical resistance, heat resistance, electrical insulation, high strength mechanical properties and good high wear processing performance; plasticity; good grafting and composite function
2, PC: with high strength and elasticity coefficient, high impact strength, wide range of temperature; high transparency and free dyeing; forming Low shrinkage, good dimensional stability; good fatigue resistance; good weather resistance; excellent electrical characteristics.
