China Rotomolding HDPE Manufacturer, Supplier, Factory

Rotomolding HDPE is a white powder or granular product. Non toxic, odorless, with a crystallinity of 80% to 90%, a softening point of 125-135 ℃, and a usage temperature of up to 100 ℃; Hardness, tensile strength, and creep resistance are superior to low-density polyethylene; Good wear resistance, electrical insulation, toughness, and cold resistance; Good chemical stability, insoluble in any organic solvent at room temperature, resistant to corrosion by acids, alkalis, and various salts; The film has low permeability to water vapor and air, and low water absorption; The aging resistance is poor, and the environmental stress cracking resistance is not as good as low-density polyethylene. Especially, thermal oxidation can cause its performance to decline. Therefore, antioxidants and UV absorbers need to be added to the resin to improve this deficiency. High density polyethylene film has a lower thermal deformation temperature under stress, so attention should be paid when applying it.
