The Tree Properties of Polypropylene Thin Film

폴리프로필렌(Polypropylene)박막의 트리현상

The polypropylene has been known to have higher melting temperature than Polyethylene. and good mechanical properties. This paper introduces the experiment result for tree properties of polypropylene thin film with a crystal structure. According to the experiment. tree properties is appeared boundary section of thin film first of all. Also, Spherulites magnitude of slow cooling is larger than that of rapid cooling.
