Dow announced the launch of DOWSIL 5-1050 Polymer Processing Aid (PPA), 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, among others, like melt fracture mitigation and die lip build up suppression in linear low density polyethylene grades, leading to high quality films.

"Historically, fluoropolymer-containing PPAs worked efficiently for most film applications and other processes,” said Mubashir Ansari, Technical Service & Development Scientist at Dow. “Now that those are being phased out, converters are looking for effective alternatives. With DOWSIL™ 5-1050 PPA, 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.”

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.
