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
Characteristics of LLDPE
Here are some common characteristics of LLDPE (Linear Low-Density Polyethylene):
1. Flexibility: LLDPE is known for its high flexibility and excellent elongation properties. It can be easily stretched or molded without breaking, making it suitable for applications that require flexibility.
2. Toughness: LLDPE exhibits excellent toughness and impact resistance. It can withstand heavy loads and rough handling without cracking or breaking.
3. Chemical Resistance: LLDPE is resistant to a wide range of chemicals, including acids, bases, and solvents. This makes it suitable for applications where exposure to chemicals is expected, such as in chemical storage containers or industrial liners.
4. Moisture Barrier: LLDPE has good moisture barrier properties, which make it useful for applications where protection against moisture is important. It can be used for packaging materials to prevent moisture ingress and maintain the quality of the contents.
5. Excellent Sealability: LLDPE can be easily heat sealed, making it suitable for applications that require airtight or watertight seals. It is commonly used in packaging films and bags where sealing is necessary.
6. Low Density: As the name suggests, LLDPE has a lower density compared to other types of polyethylene. This results in lighter weight products and can help reduce material usage and transportation costs.
7. Good Electrical Insulation: LLDPE possesses good electrical insulation properties, which make it suitable for applications in the electrical and electronics industry.
8. UV Resistance: LLDPE can be formulated with additives to enhance its resistance to ultraviolet (UV) radiation. This makes it suitable for outdoor applications where exposure to sunlight is expected, such as agricultural films or outdoor storage covers.
