Crystallinity pp
WebNot only the type of polymer (e.g. Polyethylene PE or Polypropylene PP) but also the crystallinity D are important observables for polymer materials. In a highly industrialized environment, it is equally important for users as well as producers to quickly screen products for the latter properties. WebOct 1, 1998 · The effect of crystallinity on the fracture behaviour of polypropylene was studied under impact conditions. The crystallinity was varied by taking low- and high-isotactic polypropylenes and mixtures thereof. The crystallinity ranged from 31 to 53 m s −1 1. Introduction
