Newly introduced PFAS-free processing aids for

by Polymer Dynamix, is finding use in film and pipe and profile applications. In recent production trials in extrusion of pipes and profiles, the com- pany says quality of the pipe surface, wall thickness and diameter were maintained, and reduced energy consumption was noted. “Motor power consumption dropped by 10%,
indicating significant energy savings without compromising output,” says Moritz Winkler, Senior New Business Development Manager at Mitsui in Germany. “Further testing suggests the possibility of a 10% increase in output while maintaining the same motor load. The combined results translate to an estimated 15% efficiency gain, offering both economic and environmental benefits.” EverGlide PA has ISO 10993 certification, which allows its use in medical applications such as
films from Tosaf are reported to have shown good results in both laboratory testing and commercial extrusion of metallocene LLDPE. Optical proper- ties, such as transmission, haze and clarity, were said to have been improved using the new additive compared to the previously used conventional processing aid. Other benefits were said to include lower melt temperature and reduced occurrence of melt fracture.
Masterbatch options According to Ampacet, its new PFAS-free PPA masterbatches for blown film extrusion can be used at the same let-down ratios as its other common fluoropolymer-based PPA masterbatch products, including a solution for resin producers accustomed to using very low concentrations. The line includes an FDA food contact-compliant PFAS-free PPA, a globally-compliant PFAS-free PPA, and a grade that is globally compliant and silox- ane-free. The company says the additives eliminate melt fracture, reduce die buildup, and offer increased throughput similar to fluoro-based alternatives. A range of PFAS-free PPAs suitable for different polymers and conversion processes, including blown and cast film, is now available from Kafrit Group, which includes Israel-based Kafrit, Constab
MIXING MISSION? POSSIBLE!
Zeppelin heating / cooling mixer: Keep cool – for top products.
The higher the homogenization, the better the quality: Zeppelin heating / cooling mixers generate an intense, three-dimensional mixing effect - the basis for high quality products. And they ensure effective aspiration to perfectly dehumidify the mix for optimal further processing. All for an excellent product quality.
