Product type
Polypropylene (PP) is a versatile thermoplastic polymer widely used in various industrial applications. It is known for its excellent chemical resistance, low density, and high tensile strength, making it suitable for a wide range of products. Polypropylene is produced through the polymerization of propylene monomers, resulting in a lightweight material that can be molded into various shapes and forms.
| Material type | Thermoplastic polymer |
| Density | 0.90 to 0.92 g/cm³ |
| Melting point | 160 to 170 °C |
| Tensile strength | 30 to 50 MPa |
| Elongation at break | 200 to 600% |
When selecting polypropylene, buyers should consider the specific grade required for their application, as different grades offer varying properties such as impact resistance and clarity. It is also important to specify the desired thickness, color, and any necessary certifications for food safety or environmental compliance. Quantities should be clearly stated to ensure accurate pricing and availability.
