Plastic Sheets Polypropylene Plastic Sheet Manufacture Plate Factory Price |Xicheng ,PP sheet, polypropylene extruded sheet is a plastic sheet made of PP resin added with various functional additives through extrusion, calendering, cooling, cutting and other processes. PP board is a semi-crystalline material. It is harder than PE and has a higher melting point.
Description
Polypropylene PP is a semi-crystalline material. It is deeper than PE and has a higher melting point. Since the homogeneous PP sheet becomes brittle and easy to break when the temperature is lower than 0??, many commercial PP sheets add 1~4% ethylene raw material to improve the flexibility of the sheet.
The strength of polypropylene PP increases with the increase of ethylene content. The melting point temperature of polypropylene is 154??C. Due to the increased crystallinity, the board surface and scratch resistance of this material are very good. PP board is usually used in a corrosion-resistant environment, and the PP is improved by adding glass fiber, metal additives or thermoplastic rubber.
