According to the Corrugated Plastic Sign manufacturer, the main material of the plastic hollow board is polypropylene, which can be divided into isotactic polypropylene (IPP), syndiotactic polypropylene (SPP), and random polypropylene (APP):

PP polypropylene epoxy resin is a low-density plastic, it is a milky white high-crystalline polymer. It also has excellent physical and technological properties, rigidity, abrasion resistance, high strength, high-temperature resistance, and no water absorption. The electric strength is good.

Polypropylene plastic crafts can be formed by extruders, plastic machines, hollow injection molding, welding, and heating molding or polyurethane foam molding, or mechanical processing and manufacturing methods, and the surface of the crafts can also be electroplated. The plastic hollow board is produced and formed according to the extruder. It not only inherits the advantages of polypropylene, but also improves its dyeing agent, packaging and printing, and adhesion in the production and processing. Various kinds of protection can be added during manufacturing. Electrostatic materials and flame-retardant materials have improved characteristics, which expands its application function and scope.

The main uses of polypropylene plastic are very wide. It can not only be made into plastic hollow boards but also various plastic films, hollow crafts, injection craft crafts, various pipe fittings, plate, and sheet crafts, flat belts, and chemical fibers. And other crafts.
