PP Sheet Series

PP (polypropylene) is a semi-crystalline thermoplastic, a general-purpose plastic with the lowest density, lowest cost, and balanced overall performance. Its applications cover almost all light industry, home appliances, automobiles, and packaging fields. Characteristics:
1. Extremely low density: 0.90–0.91 g/cm³, the lightest among general-purpose plastics, with good strength and rigidity.

2. Excellent chemical resistance: resistant to acids, alkalis, salts, and most organic solvents.
Non-absorbent, extremely low water absorption, but not resistant to strong oxidants, aromatics, and chlorinated hydrocarbons.

3. Excellent electrical insulation, good high-frequency performance, suitable for wires and electrical appliances.

Production:
1. Melting
2. Three-roll calendering and shaping
3. Cooling and conveying
4. Cutting

Advantages:
1. Inexpensive raw materials, cost far lower than PC, ABS, and PMMA.
2. Low processing temperature, saving electricity and reducing equipment wear.
3. PP is non-absorbent, eliminating the need for a drying process.
4. Good flowability, stable extrusion, and high output.
5. Good sheet toughness, not easy to crack, weldable and bendable.
6. Resistant to acids and alkalis, corrosion resistant, in high demand in the chemical industry.
7. Can be made into food-grade and environmentally friendly sheets.
