服务热线The characteristic of polyethylene PE is that it is insoluble in water and has very little water absorption. Even for some chemical solvents, such as toluene, acetic acid, etc., it only slightly dissolves at a temperature above 70°C. The plastic folding box made of polyethylene has good wear resistance, strong impact resistance, light weight and long service life. Because polyethylene contains a lot of organic solvents, the plastic folding box made of polyethylene also has good corrosion resistance and will not be damaged in an oxidizing environment. The shortcomings of PE polyethylene have general mechanical properties, low tensile strength, poor creep resistance, and good impact resistance. The high-density polyethylene plastic folding box has good toughness and good impact resistance, but its service life is greatly affected by the environment. Especially in the north arid and low temperature weather environment, the low temperature resistance is poor, and it is easy to be brittle and break when used for long-term turnover.
Polypropylene PP has hard texture, good cold resistance, high chemical stability, acid, alkali and organic solvent resistance, and odorless; PE material has high crystallinity, non-polar thermoplastic resin, has good heat resistance, cold resistance, and chemical stability Good, it also has high rigidity and toughness, and good mechanical strength. In layman's terms, PP is hard and brittle, and PE has good flexibility, both of which are raw materials to ensure high-quality plastic folding boxes!
