Analysis of the characteristics of high density polyethylene board

HDPE board is a kind of thermoplastic resin with high crystallinity and non-polarity. The appearance of the original high-density polyethylene was milky white, and the cut surface was translucent.

HDPE boards have excellent corrosion resistance to most household and industrial chemicals. Certain types of chemicals cause chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (carbon tetrachloride). The polymer does not absorb water, has good water vapor resistance, and can be used for packaging. High density polyethylene has good electrical properties, especially high dielectric strength, and is very suitable for wire and cable. Medium to high molecular weight grades have excellent impact resistance, even at room temperature and low temperatures of -40F. The unique characteristics of different grades of high-density polyethylene are an appropriate combination of four basic variables: density, molecular weight, molecular weight distribution, and additives. Different catalysts are used to produce custom polymers with special properties. These variables are combined to produce different grades of high-density polyethylene for different applications with the best balance of performance. It has good chemical stability and can resist most acids, alkalis, organic solutions and hot water. Good electrical insulation
