In principle, high-density polyethylene pipe-specific resins with a pressure rating of MRS 8 (PE80) can be polymerized by one of several low-pressure polymerization processes. MRS 10 (PE100) pipe-specific resins are typically produced in a series, bimodal or multimodal polymerization process.
Bimodal or multimodal polymerization processes can be tailored to meet the needs of different sectors and customers. For new pipe materials, rigidity, toughness, processability and long-term performance are all important. The commonality of all PE100 polymerization processes is that at least 2 polymerization reactors are connected in series.
