Characteristics

Low-density polyethylene, also known as high-pressure polyethylene (LDPE): good flexibility, extensibility, electrical insulation, transparency, easy processing and certain air permeability. Its chemical stability is good, alkali resistance,resistance to generalOrganic solvents.

High density polyethylene (HDPE): can reach 100 ℃; the hardness, tensile strength and creep property are better than low-density polyethylene; the wear resistance, electrical insulation, toughness and cold resistance are better; the chemical stability is good, at room temperature, Insoluble in any organic solvent, resistant to acid, alkali and various salts; the film has small permeability to water vapor and air, and low water absorption;surface hardness, tensile strength, rigidity and other mechanical strengths are higherLDPE, close to PP, is tougher than PP, but the surface finish is not as good as PP;poor aging resistance, environmental stress cracking resistance is not as good as low-density polyethylene, especially thermal oxidation will reduce its performance, so the resinmust be addedto improve this deficiency. High density polyethylene film instress, and when applied.

Linear low density polyethylene (LLDPE) has excellent environmental stress cracking resistance and electrical insulation, high heat resistance, impact resistance and puncture resistance.

Application

Application scope of low density polyethylene: suitable for food packaging such as seasonings, cakes, sugar, candied fruit, biscuits, milk powder, tea, fish floss, etc. Tablets, powders and other pharmaceutical packaging, shirts, clothing, knitted cotton products and chemical fiber products and other fiber products packaging. Washing powder, detergent, cosmetics and other daily chemical products packaging. Due to the poor mechanical properties of single-layer PE film, it is usually used as the inner layer of composite packaging bags, that is, the heat-sealable substrate of multi-layer composite film.

    High density polyethylene is used to extrude packaging films, ropes, woven bags, fishing nets and water pipes. Injection molding of low-grade daily necessities and shells, non-load-bearing components, plastic boxes and turnover boxes; Extrusion blow molding containers, hollow products, bottles.

Linear low density polyethylene produces films, daily necessities, pipes, wires and cables through injection molding, extrusion, blow molding and other molding methods.

Polyethylene (referred to as PE) is a thermoplastic resin, the monomer is ethylene. Polyethylene is odorless, non-toxic, and wax feeling. It has excellent low temperature resistance (the minimum service temperature can reach -100 ~-70 ℃), good chemical stability, and can withstand most acid and alkali corrosion (not resistant to oxidizing acids). Insoluble in general solvents at room temperature, low water absorption, excellent electrical insulation.
