PP plastic is the abbreviation for PolyPropylene, a hard thermoplastic and a polymer with high mechanical strength.
Characteristic:
- Light weight: PP has a low density (0.90–0.92 g/cm³), making it a lightweight material.
- Mechanical strength: Good bearing capacity, high hardness but flexible.
- Chemical Resistance: Resistant to many chemicals, solvents, and moisture.
- Melting temperature: About 130-171°C (266-340°F).
Application: Food packaging, food containers, bottles, household appliances, auto components, medical instruments.
