Products Description
Linear low density polyethylene (LLDPE) is the most produced variety of polyethylene (PE) resin, which first appeared in the 1970s. LLDPE Raw Materials is non-toxic, tasteless, odorless, and milky white in appearance. Its molecular chain structure is linear, and α-olefin monomers are introduced in the polymerization process to form a considerable number of branched chains on the main chain of the molecule. The different lengths of branched chains in the molecular structure will have a great impact on the performance of the final product, and the polymer performance can be adjusted by adjusting the length of the branched chains, the branching degree and the content of copolymer monomers. As a result, LLDPE Raw Materials has unique advantages in various industries and various applications. The main production processes for LLDPE are high-pressure, solution, slurry and vapor phase methods.
| Main Processes of LLDPE | ||
| No. | Processes Method | Introduction |
| 1 | High-pressure | The high-pressure method is represented by Exxon ob1's high-pressure tubular process and Mitsubishi Oil & Chemical's high-pressure tubular process. |
| 2 | Solution | Proven processes for solution methods include Du Pont's Sclairtech medium pressure process, DSM's low pressure adiabatic process, and Dow Chemical's low pressure cooling process. |
| 3 | Slurry | Typical processes for slurry methods include Nissan Chemical's stirred kettle process, Mitsui Oil & Chemical's CX process Lyonde11Base11's Hostalen process and Konoco Phillips Petroleum's annular tube process, INEOS (formerly BP) Inovene S (Solvay) low pressure slurry process and Borealis' Borstar annular tube-gas phase process. |
| 4 | Vapor Phase | The main vapor phase processes are the Spherilene process of Lyonde11Base11, the Innovene G process of INEOS (formerly BP) and the Unipol process of Univation. |
