Anti-corrective Sheet Material PP sheet for Industry |Xicheng ,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
The strength of polypropylene PP increases with the increase of ethylene content. The melting point temperature of polypropylene is 150??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.
The flow rate MFR range of polypropylene PP board is 1-40. PP materials with low MFR have lower impact resistance but lower elongation strength. The shrinkage rate of PP is quite high, 1.8~2.5%. And the directional uniformity of shrinkage is much better than that of PE-HD materials. Adding 30% of glass additives can reduce the shrinkage to 0.7%. Both type and fluid type PP materials have excellent moisture absorption, acid and alkali resistance, alkali resistance, and solubility resistance. However, it does not melt at high temperatures like PE for PP boards such as gasoline (such as benzene) solvents and industrial hydrocarbons (carbon tetrachloride) solvents.
