Dow has launched DOWSIL™ 5-1050 Polymer Processing Aid (PPA), a new material designed for use in blown and stretch film applications as an alternative to fluoropolymer-based processing aids, which are being phased out in various markets due to regulatory and environmental concerns.
This new PPA, formulated with a silicone additive in a polyethylene carrier, is supplied as a masterbatch, enabling seamless integration into existing extrusion processes. Dow states that DOWSIL™ 5-1050 PPA addresses industry needs for reliable processing aids that do not rely on fluoropolymers, which have come under increasing scrutiny.
The material is compatible with a broad range of film applications and resin types. It has demonstrated industrial-scale performance benefits, including reduced melt fracture, lower haze for improved film optics, and suppression of die lip buildup—helping converters reduce downtime and material waste. It also contributes to lower die pressure, which can enhance extrusion efficiency.
The product complies with both European Commission Regulation (EU) 10/2011 and U.S. FDA 21 CFR 174.5 for food contact safety.
“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.”
DOWSIL™ 5-1050 PPA is currently available in both sample and commercial scale quantities, as Dow continues supporting the packaging industry’s transition to alternative processing technologies.
