Such mysterious polyethylene sheet you seen it?

Aug 10, 2017

Polyethylene sheet, also known as low-pressure high-density polyethylene, HDPE board, PE board, HDPE rod, it is a high crystalline, non-polar thermoplastic resin. The appearance of the original HDPE was milky white, in the meager section showed a certain degree of translucent.

PE sheet has excellent resistance to most of the characteristics of life and industrial chemicals. Certain types of chemicals can produce chemical corrosion, such as 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 applications.

HDPE has good electrical properties, especially dielectric dielectric strength, making it very suitable for wire and cable. Medium to high molecular weight grades with excellent impact resistance, at room temperature and even at -40F low temperature are so, the unique characteristics of various grades of HDPE is the appropriate combination of four basic variables: density, molecular weight, molecular weight distribution and additives The Different catalysts are used to produce custom special properties polymers. These variables combine to produce different grades of HDPE grades; achieve the best balance in performance. Has good chemical stability, can resist most of the acid, alkali, organic solution and hot water erosion. Good electrical insulation.

Polyethylene board odorless, non-toxic, feel like wax, with excellent low temperature performance (minimum temperature up to -70 ~ -100 ℃), chemical stability, and resistance to the majority of acid and alkali erosion (intolerance with oxidation Nature of the acid), at room temperature insoluble in the general solvent, water absorption, electrical insulation performance; low density; good toughness (the same applies to low temperature conditions); good tensile; electrical and dielectric insulation is good; low water absorption ; Water vapor permeability is low; good chemical stability; tensile; non-toxic harmless.
