Lotte Polypropylene (PP) Granules Product Details
Polypropylene (PP) Granules Product Description
Polypropylene (PP) is a high-performance thermoplastic polymer produced from the polymerization of propylene monomers. It is known for its excellent mechanical properties, chemical resistance, and lightweight nature. PP granules are widely used in various industries due to their high melting point, durability, and ease of processing.
Key Features:
- High tensile strength and stiffness
- Excellent impact and chemical resistance
- Superior heat resistance with a high melting point
- Lightweight and durable
- Good processability for injection molding, extrusion, and blow molding
- Recyclable and environmentally friendly
Production Process
PP granules are manufactured through a controlled polymerization process using advanced catalyst systems. The production involves the following steps:
- Raw Material Preparation – Propylene monomer is purified and fed into the reactor.
- Polymerization – The polymerization occurs using a catalyst system in gas-phase or bulk-phase reactors.
- Separation & Purification – Unreacted monomers are separated and recycled, while the polymer is purified.
- Extrusion & Pelletizing – The molten polymer is extruded into strands, cooled, and cut into uniform granules.
- Quality Control & Packaging – The final product undergoes stringent quality testing before being packed for distribution.
