According to the polymerization method, low-density polyethylene can be divided into the high-pressure method and low-pressure method. According to the type of reactor, it can be divided into the kettle method and the tube method. Using ethylene as raw material, it is fed into the reactor, and the polymerization reaction is carried out by high-pressure compression under the action of the initiator. The material coming out of the reactor, after the unreacted ethylene is removed by the separator, it is melted, extruded, granulated, dried, blended, and sent for packaging.
Frequently Asked Questions
LLDPE Applications
LLDPE (Linear Low-Density Polyethylene) is a type of polyethylene that has numerous applications due to its unique properties.
1. Film and Packaging: LLDPE is commonly used in the production of various films, including stretch films, shrink films, agricultural films, and food packaging films. Its flexibility, high tensile strength, and puncture resistance make it ideal for these applications.
2. Rotomolding: LLDPE is widely used in the process of rotational molding, which involves melting the polymer and rotating the mold to evenly coat its inner surface. This technique is commonly used to produce large, hollow objects such as tanks, containers, and playground equipment.
3. Extrusion Coating: LLDPE can be used as a coating material in extrusion coating processes. It is applied as a thin layer to provide moisture resistance, heat sealing properties, and improved appearance to various substrates, such as paperboard, aluminum foil, and woven fabrics.
4. Wire and Cable Insulation: LLDPE is used in the production of wire and cable insulation due to its excellent electrical insulation properties. It provides protection to the conductors and helps maintain electrical integrity.
5. Injection Molding: While LLDPE is not as commonly used in injection molding compared to other polyethylene types like LDPE (Low-Density Polyethylene) or HDPE (High-Density Polyethylene), it can still be employed for certain applications that require flexibility and impact resistance.
6. Geomembranes: LLDPE geomembranes are used in civil engineering and environmental applications such as landfill liners, mining industry containment, and pond liners. These geomembranes provide a durable barrier to prevent the migration of fluids or contaminants.
