Czech-based Unipetrol RPA teams up with Milliken on a new low melt-flow rate HPP grade for packaging


Unipetrol RPA, a Czech refinery, petrochemical and agrochemical raw materials producer, has launched a low melt-flow rate polypropylene homopolymer (hPP) grade based on Milliken's Hyperform HPN-600ei nucleating agent. The new development, Mosten FT005, is said to significantly up the aesthetics and processing performance of thermoformed rigid packaging, such as beverage cups and yogurt packaging, according to Unipetrol.

The new Mosten FT005 is a bimodal hPP resin incorporating Milliken's Hyperform HPN-600ei nucleating innovation with an antistatic agent. Unipetrol said the grade brings improved transparency and a glossy surface to end products, while also featuring well-balanced processing properties to ease parts production for converters.

Mosten FT005 is the result of a partnership between Unipetrol, its R&D center Polymer Institute Brno (PIB) and Milliken. Following initial discussion and research of market needs, PIB provided technical support to Unipetrol throughout the development process. This included preparation of laboratory samples and investigation of basic processing and mechanical properties. Milliken also helped with resin evaluation during initial production of thermoformed parts. ...
