1.High chemical resistance: PP exhibits excellent resistance to a wide range of chemicals, including acids, alkalis, and solvents. This makes it suitable for applications involving contact with various chemical substances.
2. Low density: PP is a lightweight material with a low density, which makes it ideal for applications where weight reduction is desired. It offers a high strength-to-weight ratio. Such use for the school bag trolley plastic part.
3.Good heat resistance: PP has a relatively high melting point, allowing it to withstand elevated temperatures without significa nt deformation. It has a heat resistance of around 130-170 C (266-338 F), depending on the grade. Such use for Bag bottom , PP bag Bottom.
4. Excellent moisture resistance: PP is highly resistant to moisture absorption, making it suitable for applications in humid or wet environments. It does not absorb water easily, which helps maintain its mechanical properties.
5.High impact resistance: PP exhibits excellent toughness and impact resistance, making it suitable for applications where parts need to withstand sudden impacts or loads.
6. Low cost: PP is relatively inexpensive compared to other engineering plastics, making it a cost-effective choice for many applications.
