LDPE HP2023jn Low Density Polyethylene Virgin LDPE Granules

Basic Properties: Polyethylene belongs to the category of non-polar, high crystallinity, low density, non-Newtonian fluid type linear polymers (HDPE) or branched chain polymers (LDPE).
Low-pressure synthesis of HDPE, also known as low-pressure polyethylene, density of 0.94-0.96g/cm3, crystallinity of 80%-90%; high-pressure synthesis of LDPE, also known as high-pressure polyethylene, density of 0.91-0.94g/cm3, crystallinity of 65%; improve the synthesis of LDPE formulated by the process of LLDPE, density of 0.92-0.925g/cm3. Crystallinity is 65%-75%. In addition, there are medium-density PE (MDPE), density of 0.926-0.94g/cm3, performance and HDPE similar; ultra-low density PE, density of 0.88-0.91g/cm3, it is low crystallinity, softer texture.
Processing performance: PE plastic can be used for injection moulding, extrusion, blow moulding, pressing, calendering, coating and other moulding processes to process all kinds of products. (1) PE moulding process is good, low processing temperature, low injection pressure. Decomposition temperature of 300 degrees, good thermal stability, but poor oxidation, the ingredients should be added to the antioxidant. (2) PE is easy to crystallise, processing needs to control the mould temperature to control the degree of crystallisation, so that it has different properties. (3) PE water absorption is small, generally do not need drying treatment before processing, and generally do not need post-treatment after processing. If you need to deal with, can be in 80 degrees in a variety of media processing 1-2 hours, and then cooled to room temperature can be. (4) PE moulding shrinkage and orientation.
Applications: (1) film packaging field, such as shopping bags, cling film, rubbish bags, winding film, household film, etc.; (2) injection products, such as crates, caps, shells, trays, containers, etc.; (3) extruded products, such as sheets, plates, tubes, pipes, filaments, fishing nets, filters, textile bags, etc.; (4) hollow blow moulding products, such as all kinds of bottles, tanks, etc.; (5) other applications such as cable wire (5) Other applications such as cable wire, coating, etc.
