Japan’s Mitsui Chemicals recently announced that the company will start producing high-density polyethylene (HDPE) products on a pilot plant using PI (phenoxyimine) catalysts this fall. The company plans to build a new commercial production facility using this catalyst by 2007.
Mitsui Chemicals stated that HDPE produced using PI catalyst has high strength, and the pipes and films produced from this HDPE are 30% thinner than those produced by conventional HDPE. Mitsui hopes that this product will become the core product of the next-generation HDPE.
Mitsui Chemicals said that although the company has not yet finalized the capacity of the new plant, it is expected that the production capacity will exceed 200,000 tons/year from the perspective of cost advantage. The process technology is likely to use the metallocene LLDPE gas phase method, because Mitsui has accumulated a wealth of experience in this area.
The PI catalyst is a new generation of polyolefin catalysts developed by Mitsui which has a catalytic effect 300 times that of metallocenes. It not only produces ultra-high molecular weight polyethylene products, but also obtains molecular designs with special properties. In polymer commercial products, the catalyst showed better affinity with HDPE, and Mitsui decided to bring the product to market as soon as possible.
