PP sheet is a semi crystalline material. It has a higher melting point than PE. Due to the brittleness of PP at temperatures above 0 ℃, many commercial PP materials are irregular copolymers with 1 to 4% ethylene added.

1. PP sheet classification

(1) Pure PP board: low density, easy to weld process, superior chemical resistance, heat impact resistance, non-toxic odorless, it is the most environmentally friendly engineering plastic. The main colors are white microcomputer color, other colors can also be customized according to customer requirements.

(2) Polypropylene extruded sheet: It is a plastic sheet made by adding various functional additives PP resin through extrusion, rolling, cooling, cutting other processes.

(3) Glass fiber reinforced PP board: After 20% glass fiber reinforcement, the strength stiffness are doubled compared to PP, it has good heat resistance, low temperature impact resistance, corrosion arc resistance, low shrinkage rate.

2. Characteristic application

(1) PP sheet has the characteristics of light weight, uniform thickness, smooth surface, good heat resistance, high mechanical strength, excellent electrical insulation, good chemical stability, non toxicity.

(2) PP sheet is widely used in chemical containers, machinery, electronics, electrical appliances, food packaging, decoration water treatment, etc. The actual temperature of the Pp board can reach 100 degrees.

3. Range of colors used

(1) The commonly used colors for PP sheets include beige, green, blue, porcelain white, milky white, semi transparent, other colors can also be customized.
