Hollow board (also called hollow Gezi board, Vantone board, corrugated board, double-siding) English name: pp plate sheet, is a light weight (hollow structure), non-toxic, pollution-free, waterproof, shockproof, anti- aging, corrosion-resistant, color-rich new materials, product structure compared to cardboard, 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. Hollow plate mainly used in electronics, packaging, machinery, light industry, postal services, food, medicine, pesticides, household appliances, advertising, decoration, stationery, magneto-optical technology, bio-engineering and other medical and health industries. Is a new type of environmentally friendly packaging materials. PP hollow board is a green material, widely used abroad in the country is just beginning, and gradually replace part of the corrugated packaging materials, some domestic companies are now also being developed for use as building decoration materials! PP hollow board because of its widespread use, easy to use, also known as MassMutual board, which is widely used in advertising background, stationery materials, industrial packaging, earthquake and other products, we are the most common crates, removable combination boxes, product packaging boxes and boxes and other partitions. Hollow board commonly used environmental pollution recyclable thermoplastic polypropylene (PP), polyethylene (HDPE) resins and various accessories made of addition there is a polycarbonate (PC) hollow board, also known as solar panels, glass Karp Long board, PC hollow sheet, is a high-performance engineering plastics PC resin processing, with high transparency, light weight, impact resistance, noise insulation, flame retardant, anti-aging, etc., is a high-tech, integrated unsurpassed performance, energy-saving type of plastic sheet, is currently widely used internationally plastic materials.
