Polypropylene is a thermoplastic polymer that closely resembles HDPE in appearance. It's commonly used in the manufacturing of automotive parts, molded pieces, or containers. Its high resistance to chemicals makes it an ideal material for designing containers for corrosive substances.
Polypropylene maintains an excellent balance among its thermal, chemical, and electrical properties. It is tear-resistant, highly flexible, and withstands repetitive bending. It's important to note that it's not recommended for use in freezing temperatures as it becomes brittle at low temperatures. Lastly, it exhibits lower resistance to UV rays compared to HDPE.
