Baerlocher USA Launches PFAS-free PPAs for Rapid Melt Fracture in HDPE and LLDPE

-

Baerlocher USA, part of the Baerlocher Group, announces the introduction of Baerolub® AID polymer processing aids (PPAs) to help customers smooth transition from per- and polyfluoroalkyl substances (PFAS).

Baerlocher’s new PPA for blown film, pipe and wire & cable are free of PFAS and siloxanes, are cost-competitive with existing and new PPA solutions, and are compatible with other additives used in film, such as anti-block or slip agents.


Providing Better Haze Performance than PFAS-PPAs


Baerolub AID PPAs deliver rapid melt fracture clearing for metallocene and Ziegler Natta linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE), equaling or surpassing clearing times of traditional PPAs containing PFAS.


Because Baerolub AID PPAs are soluble in the polymer matrix, they provide better haze performance than insoluble PFAS-containing PPAs and excellent control of frost line height. Baerlocher USA’s new products can also reduce die build-up and extruder pressure. Because they are designed for maximum compliance with global food contact regulations, Baerolub AID PPAs are well suited for applications including polyethylene films for food packaging and resins for potable water pipes.


Baerolub AID products are available as neat additives (pastilles, rods, granules and powders), custom blends and in masterbatch form. Baerlocher also offers customers regulatory expertise and support for lab and technical screening, blown film testing and preparation for production trials.


“Current and evolving European Union and U.S. Federal and state regulations are forcing the plastic industry to look for new alternatives to PFAS-based processing aids,” said Chad Harlan, strategic business unit head, Baerlocher. “To meet this need, Baerlocher USA developed Baerolub AID PPAs featuring proprietary, PFAS-free chemistry; a breakthrough that has propelled us into a leading position in the PPA space. Our new products check all the boxes for performance, cost-effectiveness, regulatory compliance, and reliable supply. Upstream customers are enthusiastically adopting Baerolub AID products and blown film converters routinely request our technology.”


Robert Sherman, Ph.D., technical director for Baerlocher USA, noted, “To give our customers a choice, we developed two grades of Baerolub AID. If you’re looking for the fastest time to clear the melt fracture in metallocene LLDPE, consider Baerolub AID 2201. In certain conditions, you may wish to select Baerolub AID 2202, which provides excellent melt clearing times compared to traditional PPAs.”


Baerlocher USA, part of the Baerlocher Group, a leading global supplier of plastics additives, today announced the introduction of Baerolub® AID polymer processing aids (PPAs) to help customers smoothly transition from per- and polyfluoroalkyl substances (PFAS).

Today's KNOWLEDGE Share Ever wondered how we can reduce plastic pollution in India? The Mysuru-based Defence Food Research Laboratory (DFRL), affiliated with the DRDO, has launched an eco-friendly remedy with the introduction of biodegradable water bottles. Crafted from sustainable Polylactic acid (PLA) material, these bottles not only combat plastic waste but also contribute to reducing the overall carbon footprint. The best thing about this bottle is its all-encompassing sustainability approach – the bottle, cap, and label are all compostable. This innovation, derived from 100% bio-based and renewable sources, sets us on a path towards environmental conservation and fosters a greener and more sustainable future.

Today's KNOWLEDGE Share:High and low shear rate changes in Rheology

-

Today's KNOWLEDGE Share If a relatively high Mw grade flows from thin to thick, as shown in the picture, and if the time needed to fill the thick section is way shorter than the average polymer relaxation time, the polymer will not be able to reach its higher viscosity (corresponding to higher thickness/lower shear-rate). I am assuming here the polymer reached equilibrium low viscosity in the thin section, say for instance because it is much longer. Any pressure prediction not accounting for transient rheology would then overpredict the pressure to fill.Of course the diverging flow will further complicate the situation and mess with the molecular orientation created in the thin section, but to what extent ? Since this is more of a reasonable "conjecture", don't take this for granted, and discuss or share your opinion in the comments. There are hundreds of Rheology papers on the "4:1 contraction flow". Not sure I have ever seen any on the..."1:4 expansio

Today's KNOWLEDGE Share : biobased content of polycarbonate diols

Today's KNOWLEDGE Share MCG increases biomass content of polycarbonate diols Mitsubishi Chemical Group (MCG) has introduced grades of its Benebiol biomass-based polycarbonate diols that have a higher biomass content. The product is primarily used in the manufacture of polyurethane resins for coatings in sectors such as automotive, furniture and outdoor products. It is also used in the production of artificial leather. Existing Benebiol grades had a bio-based content of 20-50%, but the new HSS and NLDS grades have a biomass content in excess of 80%. Some of its previous petroleum-derived grades have also been converted to biomass, as the NLS grades. This, the company said, allows it to offer bio-based grades of all its Benebiol products. The shift to biomass-based raw materials while maintaining high-quality functions will contribute to our customers’ efforts to achieve sustainable manufacturing. source:MCG/www.utech-polyurethane.com
