Additional Information
Polypropylene (PP) is a widely used thermoplastic known for its good chemical resistance and versatility. It offers resistance to various chemicals and solvents, making it suitable for food packaging and containers. PP exhibits high stiffness and rigidity, contributing to its use in pipes, automotive parts, and structural applications.
This material also boasts good moisture resistance, making it suitable for outdoor applications and products exposed to moisture. Additionally, PP is lightweight, contributing to its use in packaging and applications where weight reduction is important. Finally, PP is readily recyclable, enhancing its environmental sustainability.
However, PP has lower impact resistance compared to some other plastics and can be susceptible to heat distortion at higher temperatures.
