Modern chemical HDPE HDPP material is used for the plastic plate (also called the hollow isolating boards, Wantong board, double wall board, corrugated board), is a light weight hollow structure, non-toxic, non polluting, waterproof, shockproof, anti aging resistance, corrosion resistance, rich colors of the new materials, compared to the board, hollow board moistureproof, corrosion resistance, light weight, etc., advantage instead of cardboard. Compared with the injection molding product, the hollow plate has the advantages of shock proof, flexible design structure, no need to open the injection mold and the like. At the same time, the plate can be through the control of raw materials for flexible join anti-static, conductive masterbatch is produced with conductive, anti - static function of plastic hollow board, anti electrostatic plate surface resistivity can be controlled between 103 ~ 1011.
