pp/pvc Polypropylene flame retardant sheet Flame retardant high quality beige color PP plastic sheet boards |Xicheng ,The rigidity of PP sheet is very good, and it also has good heat resistance, so it is used in the inner layer of many heating products. You certainly don’t know, in fact, the internal Gwen layer of the refrigerator in your home is actually this kind of material used. Generally speaking, the larger width of the sheet is 2 meters, and the length will not exceed 5 meters. PP sheet can be used in many applications and play a very important role.
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 0.10%. 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.
