Clariant launches phthalate-free polypropylene catalysts

Chemical company, Clariant, is expanding its portfolio by launching the next-generation phthalate-free olefin polymerisation catalysts.

PolyMax 600 Series catalysts are a replacement for phthalate-based polyolefin catalysts and designed to suit a broad range of process requirements.

These catalysts, which were developed in partnership with McDermott’s Lummus Novolen Technology, will aim to meet the most demanding customer toxicity requirements, and answer the market’s increasing need for safer polypropylene solutions.

The improved performance provided by these catalysts is reportedly due to a new proprietary technology that increases catalyst activity up to 25% compared to phthalate-based catalysts. This new technology results in not only higher plant productivity, but also superior polymer properties, such as increased impact strength for better durability.

Stefan Heuser, senior vice president and general manager at Clariant Catalysts, commented: “Performance is the key difference with our new PolyMax 600 Series catalysts. We have successfully developed a phthalate-free solution that adds significant value to our customers’ businesses.

“The innovative technology, which allows customers to achieve higher productivity rates and reduced process fluctuations, is delivering excellent results - with one major polypropylene producer now estimating economic benefits to exceed US$8 million annually.”
