PE sheet is a high crystallinity, non-polar thermoplastic resin. The appearance of the original state of HDPE milky white, translucent in thin cross-section was a certain degree. PE sheet with excellent resistance to most domestic and industrial chemicals. The PE sheet odorless, non-toxic, feel like wax has excellent low temperature performance (the lowest temperature of -70 to -100 ° C), good chemical stability, resistance to most acid-base erosion (intolerance with oxidation properties acid) at room temperature is not soluble in common solvents, water absorption, excellent electrical insulation properties; low density; toughness (also at low temperatures); stretch; electrical and dielectric insulation; low water absorption; low water vapor permeability; chemical stability; tensile; non-toxic. PE sheet for environmental stress (chemical and mechanical action) is very sensitive to heat aging resistance.
