PP INJECION GRADE
NAME ： POLYPROPYLENE(PP)
STYPE ： HP500N
Features: polypropylene, is made up of propylene polymerization and obtained a thermoplastic resin.Sorted by methyl position is divided into isotactic polypropylene, atactic polypropylene and three kinds of syndiotactic polypropylene.Polypropylene with non-toxic, odourless, tasteless of milky, high crystallization of polymer density is only 0. 90, "0. 91 g/cm3, is one of the lightest of all plastic varieties. It very stable, water in the water the bibulous rate is only 0. 01%, the molecular weight of about 8, one thousand, 150000. With good dielectric properties and high frequency insulation and is not affected by humidity, but low temperature time-varying crisp, wear-resisting, easy to aging.
