Clariant launches phthalate-free catalysts for olefin polymerization called PolyMax 600 Series catalysts. The polypropylene (PP) catalyst technology was developed in collaboration with McDermott’s Lummus Novolen® technology. Consumers and brand owners are calling for phthalate-free plastics for food packaging and medical products, as phthalates are considered to be harmful substances of concern along with bisphenol-A (BPA), melamine, and volatile organic compounds (VOCs). Unlike other catalysts, PP catalysts are consumed in the polymerization process.
A new proprietary technology increases catalyst activity by up to 25 % compared to phthalate-based catalysts. This new technology leads not only to higher plant productivity but also to superior polymer properties, such as increased impact strength for improved durability.
PolyMax 600 Series catalysts are a drop-in replacement for phthalate-based polyolefin catalysts. They are designed to suit a broad range of process requirements in applications ranging from food packaging to engineered automotive parts.
