Jinhua hollow board, corrugated board Jinhua PP hollow board hollow board (also called hollow Gezi board, Vantone board, corrugated board, double-siding) English name: pp plate sheet, is a light weight (hollow structure), no toxic, non-polluting, waterproof, shockproof, anti-aging, corrosion-resistant, color-rich new materials, product structure compared to cardboard hollow plate, hollow plate with moisture, corrosion, and other advantages. Compared to injection products, hollow plate with shock, the flexibility to design the structure, without opening the injection mold, and other advantages. At the same time, the sheet can be controlled by a flexible material joined anti-static, conductive materials such as mother, to produce a conductive, anti-static function plastic hollow board sheet, anti-static sheet surface resistivity can be controlled between 106 ~ 1011. Static conductive plate surface resistivity can be controlled between 103 to 105.
