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
Excellent Properties of Linear Low Density Polyethylene
Polyethylene (PE) is one of the five major synthetic resins. Polyethylene is mainly divided into three categories: linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), and high-density polyethylene (HDPE).
Linear low-density polyethylene LLDPE is structurally different from general low-density polyethylene because no long-chain branches exist. The linearity of LLDPE depends on the different production and processing processes of LLDPE and LDPE. LLDPE is usually produced by copolymerizing ethylene and higher alpha olefins such as butene, hexene or octene at lower temperatures and pressure. The LLDPE polymer produced by the copolymerization process has a narrower molecular weight distribution than ordinary LDPE. It has a linear structure that makes it have different rheological properties. The melt flow characteristics of LLDPE adapt to the requirements of the new process, especially the film extrusion process, which can produce high-quality LLDPE products. LLDPE is used in all traditional polyethene markets, and its enhanced tensile, penetration, impact and tear resistance make LLDPE suitable for film. Its excellent environmental stress cracking resistance, low-temperature impact resistance, and warpage resistance make LLDPE attractive for pipe, sheet extrusion and all molding applications. The latest application of LLDPE is as a mulch film for lining landfills and waste ponds.
