Application

Polypropylene, with a melt index of 4g/10min, is designed to balance thermal, chemical, and electrical properties, providing moderate strength while maintaining low density. Its applications are vast due to its ability to withstand chemical attack, including resistance to aqueous solutions of inorganic salts, acids, and bases, even at elevated temperatures. Although it has limited heat resistance, polypropylene can endure conditions involving boiling water or steam sterilization. Its structural resemblance to polyethylene allows for the production of thinner films, enhancing its utility in applications like capacitors where reduced loss is beneficial. The purpose of using polypropylene, particularly with the specified melt index, is to offer a versatile and resilient material suitable for varied industrial and consumer applications. Additionally, its properties can be enhanced through the use of reinforcing agents, fillers, and copolymerization, making it a customizable solution for specific needs.
