Pp-91500 original factory BaojiangZhejiang Shanghai first class agent PP brief introduction: PPplastic, polypropylene resin, PP is a non-toxic, tasteless milkwhite highly crystalline polymer, is currently the lightest of allplastic varieties, especially stable to water, the water absorptionrate is only 0.01% in water for 14 hours. The molecular weight isabout 80 ~ 150,000, and the formability is good. However, due tothe shrinkage, the original wall products easy to dent, productssurface gloss, easy to stain.

The degreeof crystallization is mainly determined by the mold temperature.INJECTION PRESSURE: Up to 1800 BAR INJECTION SPEED: in general,high-speed injection can be used to minimize internal pressure. Ifthe surface of the product is defective, a low-speed injection at ahigher temperature should be used.Runner and gate: for coldrunner, the typical runner diameter range is 4-7 mm. It isrecommended to use a circular inlet and runner. All types of gatesare available. Typical Gate diameters range from 1 to 1.5 mm, butgates as small as 0.7 mm may be used. For the edge gate, theminimum gate depth shall be half the wall thickness; the minimumgate width shall be at least twice the wall thickness. PP materialscan be used in hot runner system.
