The main characteristics of PE plate:  PE plate odorless, non-toxic, feel like wax, has excellent low temperature resistance (the lowest temperature can reach -70~-100℃), good chemical stability, can PE plate most acid and alkali erosion (not resistant to acid with oxidizing properties), insoluble in general solvents at room temperature, water absorption is small,  Excellent electrical insulation, low density, good toughness (also suitable for low temperature conditions), good tensile properties. 。



Good electrical and dielectric insulation, low water absorption, low water vapor permeability, good chemical stability, tensile resistance, non-toxic harmless.  But PE sheet for environmental stress (chemical and mechanical action) is very sensitive, heat aging is poor.  PE sheet: English name High Density Polyethylene, PE sheet is a High crystallinity, non-polar thermoplastic resin.  

 

The appearance of the original HDPE is milky white, with a certain degree of translucency in the thin section.  Excellent resistance to most household and industrial chemicals.  Certain types of chemicals produce chemical corrosion: for example, corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (carbon tetrachloride).  The polymer is not hygroscopic and has good waterproof vapor properties, which can be used for packaging purposes.  

 

HDPE has very good electrical properties, especially high dielectric strength of insulation, which makes it very suitable for wire and cable.  Medium to high molecular weight classes have excellent impact resistance at room temperature and even low temperatures of -40F.  The unique characteristics of all grades of HDPE are the appropriate combination of four basic variables: density, molecular weight, molecular weight distribution, and additives.
