Process Aid Concentrates are PFAS-Free
Wide range of products for cast/blown film and pipe.
Polymer processing aids (PPA) that are free of per- and polyfluoroalkyl substances (PFAs). Developed by Polyfil in the U.S. and Constab in Europe, the new PPAs are said to offer the same level of performance and application range as traditional PFAS-containing solutions. Usually, standard PPAs effectively tackle multiple production issues like melt fracture, die buildup, interfacial instability, and high die pressure.
The collaboration between the companies has yielded solutions to a variety of processing technologies, different polymers, and a wide range of temperatures, the companies say. These include a single universal PPA, as well as a wide portfolio of PFAS-free masterbatches to address each flow-related challenge separately. Manufacturers can therefore to tailor their PPAs to their specific requirements for an optimum production process.
Some of the solutions have high-temperature suitability, up to 310°C (590°F). These are reportedly ideal for pipe extrusion and HDPE-based MDO films, enabling the production of mono-material films that facilitate easy recycling and promote sustainability.
