Changshu da plastic products factory smoothly on identification of the seven methods of PP plastic sheet

Polypropylene ( PP) Sheet extrusion PP resin is added to a variety of functional additives by extrusion, calender, cooling, cutting, processing and made of plastic. With a low transparency, low gloss, low rigidity, high impact strength to win the customer's favorite! Because the user's favorite cause many manufacturers found business opportunities, to reworked material instead of the original raw materials, the production of PP plastic plate for low-quality plastic flooding the market, to achieve the effect of the sham as the genuine, how to identify the PP plastic sheet it becomes the difficult problem that many users have a headache! Below smooth da plastic products factory in changshu for you on identification of the seven methods of PP plastic board!



　　1. See PP plastic sheet surface glossiness: poor gloss is recycled plastic;



　　2. See PP plastic toughness: pure raw material PP polypropylene plastic excellent toughness can be slightly curved;



　　3. See PP plastic sheet cutting cutting surface: after recycled plastic cutting inside can have different colors of impurity;



　　4. The PP plastic sheet density: PP polypropylene density of 0. 92 - — 0. 93 float on the surface of the water as the raw material of polypropylene;



　　5. For PP plastic plate heat welding: when recycled plastic welding smoke;



6, through the PP plastic sheet luminosity: recycled plastic completely the poor;



7, the PP plastic sheet density: throw water to see if the floating on the surface of the water, mostly sink of regeneration.
