Dow has launched Dowsil 5-1050 Polymer Processing Aid, which is a...New silicone-based substitutesIt is intended to replace fluoropolymer-based processing aids in film packaging applications.

At the time of this release, the packaging industry is facing increasing regulatory pressure to eliminate per- and polyfluoroalkyl substances (PFAS), commonly known as "forever chemicals," from food contact materials.

"Historically, fluorinated polymers' PPA has been able to work efficiently in most film applications and other processes," said Mubashir Ansari, a scientist in Dow's technical service and development.Since these are being phased out, processors are looking for effective alternatives. With Dowsil 5-1050 PPA, we have applied our technical expertise in silicone and polyethylene materials to provide a solution that complies with regulatory requirements without compromising performance."

This moment is crucial becauseThe EU's Packaging and Packaging Waste Regulation will prohibit PFAS in food contact packaging starting from August 2026.The U.S. regulators are also continuously strengthening restrictions on these persistent chemicals.

Performance and balance

Dowsil 5-1050 PPA contains silicone additives encapsulated in a polyethylene carrier and is supplied in pellet form for convenience.Seamlessly integrate into existing extrusion processes.The technology has been proven effective on an industrial scale and has the following key advantages:

Reduce melt fracture and haze of the film.To achieve a smoother surface and better film optical performance.

Reduce mold cavity accumulation.Thus reducing downtime and waste.

Reduce die head pressureImprove extrusion efficiency.

Compliant with EU Commission Regulation (EU) 10/2011 and US FDA 21 CFR 174.5Food Contact Safety Regulations

It can be achieved through dry blending or melt blending.Flexible joining

Industry transformation

As the industry shifts towards more sustainable alternatives, Dow, like other major polymer additive suppliers such as Clariant, Ampacet, and Arkema, is developing...Processing aids without PFAS。

"By combining such innovations with our global supply capabilities and local technical support, we aim to provide packaging customers with the confidence and resources for success in addressing the evolving industry."Ansari added."

The company utilizes blending, extrusion, and the integration of silicone additives into plastics.Decades of experienceTo support the packaging industry's transition to safer materials.
