Momentive Transforms Film Manufacturing with High-Performance PFAS-Free Product called Silquest™ PA-1
Momentive is driving the shift toward sustainable film manufacturing with Silquest PA-1, a breakthrough PFAS- free polymer processing aid. Specially designed for polyolefin film applications, Silquest PA-1 improves processability, eliminates melt fracture, reduces die pressure and buildup, and increases throughput—all without compromising film quality. Fully compliant with global food contact regulations, it’s the smarter, safer choice for high-performance flexible packaging.
Key Features Processability: Improves processability of polyolefin resins (LLDPE, LDPE, HDPE, PP, etc.). Easily
and accurately metered in open or closed systems. No residue buildup or accumulation of processing aid on metal surfaces.
Economical: Effective at 200-1000 ppm levels. Can eliminate the need for metal stearates. Reduced wear extends the service life of existing equipment.
Versatility: Can be used as a liquid additive, as a solid formulated into a carrier resin (in masterbatches), or as an ingredient in multi-component additive packages.
Food Contact Compliance: Excellent candidate to consider for polyolefin film applications that involve food contact.*

Process Efficiency Comparison Silquest PA-1 and a fluoropolymer control were tested on a lab scale blown film line. Both products were used as a processing aid in LLDPE resin [1.0g/min 190°C/2.16Kg] at 1000 ppm during extrusion [letdown from a 10% loaded 10.0g/ min 190°C at 2.16Kg LLDPE carrier resin].
