SINOPEC Low-Density Polyethylene (LDPE) Product Details
Product Description
Low-Density Polyethylene (LDPE) is a thermoplastic polymer made from ethylene monomer. It is known for its high flexibility, transparency, and excellent chemical resistance. LDPE is widely used in packaging, film applications, and various industrial products due to its lightweight and moisture-resistant properties.
Key Features:
- High flexibility and impact resistance
- Excellent chemical and moisture resistance
- Low-temperature toughness
- Good electrical insulating properties
- Recyclable and eco-friendly
Production Process
LDPE is produced through a high-pressure polymerization process of ethylene gas using either tubular reactors or autoclave reactors. The production involves:
- Ethylene Feedstock Preparation – Ethylene gas is purified and mixed with initiators.
- High-Pressure Polymerization – The reaction occurs under extreme pressure (1,500–3,000 bar) and temperature (150–300°C) to form polyethylene chains.
- Separation & Cooling – The polymerized LDPE is cooled and separated from unreacted ethylene.
- Extrusion & Pelletizing – The molten polymer is extruded into strands, cooled, and cut into uniform pellets.
- Quality Control & Packaging – The final product undergoes strict quality testing before packaging for distribution.
