Overview
LDPE Injection-molding grade can be used in the production of polyethylene foaming material, powdered coating and injection-molded products. The resin has a molecular structure with branching. It has high melt strength, good mechanical behavior, heat endurance and chemical corrosion resistance and excellent processability. Products made from this resin have many advantages such as short shaping cycle, small shrinkage rate and stable dimensions.
Applications
LDPE Injection-molding grade is principally used for producing civil detonators, pipes, plates, fruit net bags, traffic guardrails, smallsized injection-molding products (the inner part of a bottle cup) and powdered coating.
Package, Storage and Transportation
The resin is packaged in polypropylene woven bags. The net weight is 25Kg/bag. The resin should be stored in a drafty, dry warehouse and away from fire and direct sunlight. It should not be piled up in the open air. During transportation, the material should not be exposed to strong sunlight or rain and should not be transported together with sand, soil, scrap metal, coal or glass. Transportation together with toxic, corrosive and flammable substance is strictly prohibited.
