Virgin LDPE/Low-density Polyethylene

Products properties
 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.
