High density polyethylene
Other name: low pressure polyethylene
High density polyethylene (HDPE), white powder or granular product, non-toxic, tasteless, with crystallinity of 80% ~ 90%, softening point of 125 ~ 135 ºC.
Its excellent performances are as follows:
- Service temperature can reach 100 ºC.
- The hardness, tensile strength and creep properties are better than that of LDPE.
- Good wear resistance, electrical insulation, toughness and cold resistance.
- Good chemical stability, insoluble in any organic solvent at room temperature, resistant to acid, alkali and various salts.
It should be noted that the film has low permeability to water vapor and air and low water absorption, the aging resistance is poor, and the environmental stress cracking resistance is not as good as that of LDPE, expecially the thermal oxidation will reduce its performance. Therefore, antioxidants and ultraviolet absorbers must be added to the resin to improve this deficiency. The heat deformation temperature of high density polyethylene film under stress is low, which should also be paid attention to in application.
HDPE resin can be used to form plastic products by injection, extrusion, blow molding and rotary molding.
- Injection molding can be used to produce various types of containers, industrial accessories, medical supplies, toys, shells, corks and shields.
- Various hollow containers and ultra-thin films can be formed by blow molding.
3. Extrusion molding can be used to form pipes, stretching strips, binding belts, monofilaments, wire and cable sheaths, etc.
In addition, it can also be used as decorative board for building, shutters, synthetic wood, synthetic paper, synthetic film and molded calcium plastic products.
