LLDPE, with the full name of Linear Low Density Polyethylene, is a molecular structure with very short comonomer branches formed on the main chain of linear ethylene by copolymerization of ethylene and a small amount of α-olefin. It is a low-density polymer with a density between 0.915 ~ 0.930g/cm3 and a certain amount of short-chain branches. LLDPE is non-toxic, tasteless and odorless milky white particles in appearance.
According to the types of comonomer, linear low density polyethylene is mainly divided into three types of copolymers, C4 (butene-1), C6 (hexene-1) and C8 (octene-1). Among them, butene copolymer is the LLDPE resin with the largest production volume in the world, while hexene copolymer is currently the fastest growting LLDPE granules variety. In LLDPE resin, the typical amount of comonomer is 5% to 10% by weight, and the average amount is about 7%.
Linear low-density polyethylene uses ethylene as the main raw material and a small amount of α-olefins (such as 1-butene-1, 1-octene, etc.) to carry out gas-phase fluidized bed polymerization under the action of a catalyst under high pressure or low pressure. Then the reacted materials are granulated, dried, and sent for packaging.
The production of LLDPE resin starts with transition metal catalysts. A new process based on cycloolefin metal derivative catalysts is another option for LLDPE production. The actual polymerization reaction can be carried out in solution and gas phase reactors. Typically, octene and ethylene are co-polymerized with butene in a solution phase reactor. Hexene is polymerized with ethylene in a gas phase reactor. The LLDPE resin produced in the gas phase reactor is in granular form. Linear low density polyethylene is usually characterized by melt index and density. The melt index can reflect the average molecular weight of the resin and is mainly controlled by the reaction temperature. The average molecular weight is independent of the molecular weight distribution. Catalyst choice affects molecular weight distribution. Density is determined by the concentration of comonomers in the polyethylene chains. The comonomer concentration controls the number of short chain branches and thus the resin density. The comonomer concentration controls the number of short chain branches and thus the resin density.
