Dow has announced the launch of DOWSIL 5-1050 Polymer Processing Aid (PPA), which is designed to address the growing demand for film packaging manufactured without fluoropolymer-based PPAs. 

In addition to serving as an alternative to fluoro-based options, this technology offers primary benefits like melt fracture mitigation and die lip build-up suppression in linear low density polyethylene grades, leading to high quality films. 

A reliable PPA for a changing industry 

“Historically, fluoropolymer-containing PPAs worked efficiently for most film applications and other processes,” says Mubashir Ansari, technical service and development scientist, Dow. “Now that those are being phased out, converters are looking for effective alternatives. With DOWSIL 5-1050PPA, we’ve applied our technical experience in silicone and polyethylene materials to offer a regulatory-compliant option that doesn’t compromise on performance. By pairing innovations like this with our global supply capabilities and local technical support, we aim to equip packaging customers with the confidence and resources to succeed in the evolving industry.”

Key features and benefits

Engineered for a wide range of film applications and resins, DOWSIL 5-1050 PPA contains a silicone additive in a polyethylene carrier and is supplied as a masterbatch for ease of feeding into existing extrusion processes. This technology has demonstrated effectiveness at an industrial scale.

Key performance benefits include:  

• Reduced melt fracture and haze in film: Mitigates melt fracture, resulting in smoother surface and better film optics for visual appeal. 

• Die lip buildup reduction: Less downtime and scrap.  

• Lower die pressure: Enhances extrusion efficiency. 

• Food contact safety: Complies with European Commission Regulation (EU) 10/2011 and US FDA 21 CFR 174.5.

• Versatile incorporation: Can be incorporated via dry or melt blending. 

Supporting safer packaging at scale 

With decades of experience in compounding, extrusion, and the integration of silicone additives into plastics, Dow has a long track record of developing innovations that support the packaging industry’s transition toward safer, more sustainable materials. 

Sample and commercial scale quantities of DOWSIL 5-1050 PPA are now available.
