[Information] Basic Knowledge of Materials - What is Polypropylene?
Introducing basic knowledge about polypropylene materials!
Polypropylene (PP) is used in everyday goods, kitchen and bathroom supplies, packaging films, small containers such as bottles, beverage-related containers, and automotive, machinery, and electrical components. In films, there are biaxially oriented films (OPP) and non-oriented films (CPP), which are used according to their applications. For more details, the external link page provides an easy-to-understand explanation about synthetic resin materials. [Excerpt of Contents] - Polymer of propylene CH2=CHCH3 - Has a high crystallinity due to its isotactic structure, with a high melting point (165°C) - Syndiotactic polypropylene can be obtained using vanadium-based catalysts - The density of isotactic polypropylene is 0.91 g/cm³, the lowest among plastics - Used in everyday goods, kitchen and bathroom supplies, automotive, machinery, and electrical components *For more information, please refer to the external link page or feel free to contact us.
