The Gabriel-Chemie Group expands its portfolio with innovative PFAS- and silicone-free Polymer Processing Aid (PPA) masterbatches based on hydrocarbon technology. With the new MAXITHEN® PFAS-free PPA solutions, Gabriel-Chemie offers high-performance additive masterbatches for modern extrusion applications, combining process efficiency, product quality and regulatory compliance.

The specially developed solutions optimize modern extrusion processes, improve product quality and support plastics processors in meeting current and future regulatory requirements.

Polymer Processing Aids (PPAs) are versatile additives used in applications such as blown films, cast films, fibers, tapes and pipes. By forming a slip layer between the polymer melt and the machine wall, the difference in flow velocity within the polymer melt is reduced. As a result, pressure and friction inside the extruder can be minimized while typical processing issues are significantly reduced.

More performance in extrusion

The MAXITHEN PFAS-free PPA masterbatches from Gabriel-Chemie were developed to sustainably improve processing properties in extrusion while offering a high-performance alternative to conventional PFAS-based PPA systems.

The solutions support:

Prevention of die build-up
Reduction of machine pressure and friction
Enhanced process stability
Prevention of stick-slip effects
Elimination of melt fracture (“sharkskin”)
Increased transparency and surface quality
Uniform film thickness in blown film applications
Higher output and improved process efficiency

The difference between extrusion processes with and without PPA use:

Effectiveness and Efficiency

In extensive production trials, the MAXITHEN PFAS-free PPA masterbatches demonstrated comparable performance to conventional PFAS-based PPA systems while delivering excellent optical properties and stable production conditions.

Particularly in blown film applications, the solutions achieved excellent transparency, smooth surfaces and highly uniform film thickness. At the same time, die build-up was reduced and machine pressure minimized.

Ready for upcoming regulatory requirements

Conventional PPA systems are often based on PFAS due to their low surface energy and excellent slip properties, which made them an industry standard for many years. However, increasing regulatory restrictions and the requirements of the European Packaging and Packaging Waste Regulation (PPWR) are driving the growing importance of PFAS-free technologies. Among other measures, the PPWR introduces a strict ban on PFAS in food packaging applications starting in August 2026, targeting concentrations above 25 parts per billion.

The MAXITHEN PFAS-free PPA solutions support customers in preparing early for regulatory changes while ensuring high process reliability and consistent product quality.

Several PFAS-free PPA masterbatches from Gabriel-Chemie have already successfully completed the product development phase and comply with current regulatory guidelines, including food contact requirements.

Key Features & Benefits

Advanced solutions for modern applications

Gabriel-Chemie offers PFAS-free, silicone-free and silicone-based PPA masterbatches based on polyethylene and polypropylene carriers. Through continuous product development and extensive practical testing, high-performance solutions are created for a wide range of extrusion processes and material requirements.

In addition, first successful colour/PPA combination solutions have already been developed to enable even more precise adaptation to individual colour and processing requirements in future applications.
