Introduction to the Application Advantages of High Density Polyethylene Sheet

The main reason for the popularity of HDPE sheet is that HDPE sheet has very good abrasion resistance, and the molecular weight is very large, and the material's abrasion resistance and impact resistance are very good. It has good heat and cold resistance, good chemical stability, also has high rigidity and toughness, good mechanical strength. Dielectric properties, resistance to environmental stress cracking is also good. Melting temperature 220~260 C. For materials with larger molecules, it is recommended that the melting temperature range is between 200~250 C.

The material of HDPE sheet, polyethylene, has a good high temperature resistance, which makes it possible to apply in a certain high temperature environment. High-density polyethylene sheet belongs to a kind of non-smell, non-toxic, feel like wax, has excellent low temperature resistance (the lowest use temperature up to -70 to -100 ℃), good chemical stability, can resist the corrosion of most of the acids and alkalis, insoluble in general solvents at room temperature, absorption is small, excellent electrical insulation properties, strong toughness, strong tensile strength, good electrical and dielectric insulation, low water absorption, low water vapour penetration rate, low chemical good stability, war resistance, non-toxic and harmless.

High-density polyethylene sheet moulding temperature has a greater impact on the quality of the product Note that the temperature of the specific middle of the mould should be controlled slightly lower than the temperature at both ends. To have uniform and stable temperature conditions to assist; mould lip spacing should be equal to or slightly less than the thickness of the polyethylene liner, uniform and stable temperature to ensure that the flow rate of extruded molten material amount of flow rate of smooth isobaric pressure, so that the longitudinal thickness of the liner error value 1 small.
