Developing metallocene plastics

Metallocenes are organometallic coordination compounds formed by the attachment of transition metals to cyclopentadiene. Metallocene polyolefins are polymers prepared by polymerizing olefins using a metallocene as a catalyst. Metallocene polymers have many advantages, such as processability, high strength, high rigidity, and good transparency, and have received great attention from people. Therefore, many new products have been introduced. Metallocene plastics will directly impact the PP, MDPE, LLDPE, and elastomer plastic markets. At present, the demand for PE in the world is 40 million tons, and it is estimated that it will increase to 50 million tons by 2005, and most of the increase will be metallocene polyethylene. Metallocene plastics have many advantages, such as good gloss, high melt strength and film stability, and are suitable for use in food packaging, pharmaceutical packaging, shrink film and hygiene products.
