If you want to customize plastic hard case trolley cases, what are the differences between PP and PC trolley case? PP material belongs to translucent plastic, also known as Polypropylene Resin. PP material commonly used in commerce is added with copolymer, which has moisture absorption resistance, acid and alkali corrosion resistance and solubility resistance, moreover, due to the high crystallinity of this material, the surface rigidity and scratch resistance are very good, and PP material does not have environmental stress cracking problems. PC material is an excellent amorphous thermoplastic plastic with transparent comprehensive properties, also known as polycarbonate. The biggest advantage of PC material is that it has electrical insulation, extensibility, stability and chemical corrosion resistance, as well as high strength, heat resistance and cold resistance.
