Low-density polyethylene (LDPE) is a synthetic resin using a high pressure process via free radical polymerization of ethylene and is therefore also called "high- pressure polyethylene". Since its molecular chain has many long and short branches, LDPE is less crystalline than high-density polyethylene (HDPE) and its density is lower. It features light, flexible, good freezing resistance and impact resistance. LDPE is chemically stable. It has good resistance to acids (except strongly oxidizing acids), alkali, salt, excellent electrical insulation properties. Its vapor penetration rate is low. LDPE has high fluidity and good processability. It is suitable for being used in all types of thermoplastic processing processes, such as injection molding, extrusion molding, blow molding, rotomolding, coating, foaming, thermoforming, hot-jet welding and thermal welding.
Applications: LDPE film grade is for production of blowmolding packaging film etc LDPE coating grade is for BOPP, BOPET, BOPA LDPE artificial flower grade is for artificial flowers,minia-scape,textiles coating LDPE Injection molding grade used in civil detonators, pipes, traffic guardrails LDPE wire & cable grade is for producing the base materials for high-voltage chemical crosslinking polyethylene insulating material and low and medium-voltage silane crosslinking polyethylene insulating material.
