PE sheet: English Name: high density polyphylene, Chinese: polyethylene sheet, PE sheet is a high crystallinity, non-polar thermoplastic resin. The appearance of HDPE is milky white and translucent to a certain extent.
It has excellent resistance to most of the chemicals used in life and industry. Some types of chemicals produce chemical corrosion: for example, corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is non hygroscopic and has good water vapor resistance, and can be used for packaging purposes. HDPE has good electrical properties, especially high dielectric strength of insulation, which makes it suitable for wires and cables. Medium to high molecular weight grades have excellent impact resistance, even at room temperature and even at - 40F low temperature. The unique characteristics of various grades of HDPE are the proper combination of four basic variables: density, molecular weight, molecular weight distribution and additives. Different catalysts are used to produce customized polymers with special properties, and these variables are combined to produce HDPE grades with different uses; the best balance in performance is achieved. It has good chemical stability, can resist the erosion of most acids, alkalis, organic solutions and hot water, and has good electrical insulation.
Physical and chemical data
The melting point of HDPE board is about 130 ℃, and the relative density is 0.941-0.960g/cm3. It has good heat and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. The dielectric property and environmental stress cracking resistance are also good. The melting temperature is 220-260c. For materials with larger molecules, the melting temperature range is recommended to be between 200 and 250C.

Main features editing
PE board is odorless, nontoxic, waxy, with excellent low temperature resistance (the minimum operating temperature can reach - 70 ～ - 100 ℃), good chemical stability, and
It is resistant to most acid and alkali (not resistant to acids with oxidation property), insoluble in general solvents at room temperature, with small water absorption, excellent electrical insulation, low density, good toughness (also suitable for low temperature conditions), good tensile property; good electrical and dielectric insulation, low water absorption, low water vapor permeability, good chemical stability, tensile resistance, non-toxic and harmless.
However, PE sheet is very sensitive to environmental stress (chemical and mechanical effects), and its heat-resistant aging is poor.
