What are the differences between PP, PVC, PC and ABS suitcases?
1、性质不同：Pp材质是聚丙烯，是硬箱的材质之一，这种材质属于半透明的材质。Pc是聚碳酸酯的简称，也是硬箱的材质之一，这种材质属于透明的材质。ABS是最新比较流行的时尚行李箱材质。abs材质的主要特点是相比较其他材料而言较轻，表面比较柔韧。PVC材质的行李箱也就是硬箱。
Different properties: Pp material is polypropylene, which is one of the materials of hard. This material is semitransparent. Pc is short for polycarbonate and one of the hard materials. This material is transparent. ABS is the latest fashionable luggage material. The main characteristics of abs material are that it is lighter and more flexible than other materials. The PVC suitcase is also a hard case.
2、特点不同：Pc具有良好的耐热性耐寒性，电绝缘性和延伸性也不错，而且无毒阻燃。Pp材质的结晶度比较高，所以用pp材质制作的行李箱表面更加强硬，可以有效的防止磕碰造成划痕，而且耐冲击和防水性好。PVC材质的行李箱具有抗摔，防水，耐冲击等特点。abs材质表面比较柔韧，刚硬。
Different features: Pc has good heat and cold resistance, good electrical insulation and extensibility, and non-toxic and flame retardant. The crystallinity of Pp material is relatively high, so the suitcase made of pp material is stronger, which can effectively prevent scratches caused by bumps, and has good impact resistance and water resistance. The luggage made of PVC has the characteristics of falling resistance, water resistance and impact resistance. The surface of abs material is flexible and rigid.
3、耐磨性不同：Pp材质的耐磨性较好，但是抗冲击性和透明性较差，pc材质的耐磨性较差，但是抗冲击和透明性强，所以pc材质的行李箱柔韧性会比pp材质的好。PVC材质的行李箱耐磨性较差。
Different wear resistance: Pp material has good wear resistance, but poor impact resistance and transparency, while pc material has poor wear resistance, but strong impact resistance and transparency, so the flexibility of pc material luggage is better than that of pp material. The PVC trunk has poor wear resistance.
