Difference Between High Density Polyethylene Sheet And Low Density Polyethylene Sheet

High density polyethylene sheet (HDPE sheet) density of 0.97 ~ 0.98g/cm3. It has good heat and cold resistance, good chemical stability, but also has a high degree of rigidity and toughness, mechanical strength. Dielectric properties, resistance to environmental stress cracking is also good.HDPE plate is widely used in gas transmission, water supply, sewage, agricultural irrigation, mine fine particle solids transport, as well as oil fields, chemical industry and postal and telecommunications communications and other fields, especially in the gas transmission on the common application.

    Low-density polyethylene board (LDPE board): density of 0.92 ~ 0.93g/cm3. nature of the softer, with good extensibility, electrical insulation, chemical stability, processing performance, but the mechanical strength, moisture barrier, gas barrier  and solvent resistance is poor.
