PE material (polyethylene) and PP material (polypropylene) plastic pallet diffe

At present, the plastic pallet material that USES on domestic market basically is: polyethylene (PE) and polypropylene (PP) two kinds, because the property of raw material is different, the plastic pallet price of same model different material also has difference, use bearing capacity and use environment are not same also, the service life of pallet is not same also.

Polyethylene (PE) plastic tray, usually made of high strength polyethylene injection molding.Polyethylene is a thermoplastic resin made by polymerization of ethylene.The properties of polyethylene vary from variety to variety, mainly depending on the molecular structure and density.PE has general mechanical properties, low tensile strength, poor creep resistance and good impact resistance.High density polyethylene plastic tray toughness, impact resistance is better, but the service life of the environment is more affected.Especially in the north of the drought, low temperature weather environment, low temperature resistance ability is poor, long-term use brittle, fracture.

Polypropylene (PP) plastic tray, made of polypropylene material by injection molding or blow molding.Polypropylene is a translucent colorless solid, odorless and non-toxic.With a density of 0.90g/cm3, it is the lightest general-purpose plastic.Corrosion resistance, tensile strength of 30MPa, strength, rigidity and transparency are better than polyethylene.Disadvantage is low temperature impact resistance is poor, more easy to age, polypropylene plastic tray than polyethylene plastic tray high strength, but poor service life, easy to age.Especially in the outdoor environment, easy to aging.

Copolymerized polypropylene plastic tray, made of a new material copolymerized polypropylene.Polyethylene is made by polymerization with polypropylene.Copolymer polypropylene EPS30R is a new material.Has the high strength, the steel is big, the toughness is good, the cold weather resistance is good, especially under the low temperature condition, the chemical property is more stable than polyethylene, polypropylene.Plastic products made of copolymer polypropylene have strong impact resistance, good toughness and long service life.Copolymerized polypropylene plastic tray, especially in the north of low temperature conditions, and cold storage environment, long service life, and long-term use is not easy to deformation.Because of the limitation of extraction technology, the cost of co-polymerization polypropylene is high.
