High Density Polyethylene (hereinafter referred to as "HDPE").

It is a kind of high crystallinity, non-polar tree plastic resin, and its appearance is milky white,

In the thin section, it is translucent to a certain extent. PE has excellent resistance to most life and work

Characteristics of industrial chemicals

HDPE is a thermoplastic resin with high crystallinity and non-polarity. HDPE is non-toxic

Odorless white particles with melting point of about 130 ℃ and relative density of 0.941~0.960.

It has good heat and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. The dielectric property and resistance to environmental stress cracking are also good. The melting temperature is 120~160 ℃. For materials with large molecules, it is recommended that the melting temperature range is 200~250 ℃

Between. High density polyethylene is a white powder granular product, non-toxic and tasteless, with a density of

Within the range of 0.940~0.976 g/cm3: crystallinity is 80%~90%, softening point is 125~135 ℃,

The operating temperature can reach 100 ℃; The hardness, tensile strength and creep are better than those of LDPE; Resistance

Good abrasion resistance, electrical insulation, toughness and cold resistance, but slightly worse than low density insulation

Some; Good chemical stability, insoluble in any organic solvent at room temperature, resistant to acid, alkali and

Corrosion of various salts: the film has low permeability to water vapor and air, and low water absorption; Aging resistance

Poor performance, environmental cracking resistance is not as good as low density polyethylene, especially thermal oxidation

The performance is decreased, so the resin needs to be improved by adding antioxidants and ultraviolet absorbers

Deficiency in aspects. The thermal deformation temperature of high-density polyethylene film under stress is low

Pay attention when applying.
