Dow Launches Silicone-Based Alternative to Fluoropolymer Processing Aids for Film Packaging
- Dow launched DOWSIL™ 5-1050 Polymer Processing Aid in Shanghai on November 4, 2025, to meet demand for fluorine-free polymer processing aid film packaging solutions and replace traditional fluoropolymers.
- DOWSIL™ 5-1050 is designed for blown film and stretch film applications and excels at reducing melt fracture and die build-up on LLDPE, helping produce high-quality films.
- The product uses polyethylene as a carrier with a silicone component, is supplied as a masterbatch for direct use in existing extrusion processes, and has been validated at industrial scale.
- DOWSIL™ 5-1050 reduces die build-up to lower downtime frequency and waste, lowers die pressure to improve extrusion efficiency, and reduces melt fracture and film haze to enhance surface smoothness and clarity.
- It complies with food-contact regulations such as EU 10/2011 and US FDA 21 CFR 174.5, can be dry-blended or melt-blended with LLDPE resin, and is available in sample and production-scale quantities.
DOWSIL™ 5-1050 Polymer Processing Aid
Designed specifically for blown film and stretch film applications, it improves processing efficiency while addressing regulatory, environmental and consumer needs.
Shanghai, China, November 4, 2025 — Dow (NYSE: DOW)
today announced the launch of DOWSIL™ 5-1050 Polymer Processing Aid
to meet the market's growing demand for fluorine-free polymer processing aid film packaging solutions. The product is a silicone-based processing aid that can replace traditional fluoropolymers, and it also performs outstandingly in reducing melt fracture and reducing die build-up on linear low-density polyethylene (LLDPE), helping to produce high-quality films.
Reliable silicone-based polymer processing aids that meet evolving industry needs
"Fluoropolymer processing aids have long performed excellently in most film applications and other processes," said Mubashir Ansari, Scientist in Technical Service and Development at Dow. "As these fluoropolymer-based solutions are gradually phased out of the market, film processors urgently need equally effective alternatives. Leveraging Dow's technical expertise in silicones and polyethylene materials,
our DOWSIL™ 5-1050 Polymer Processing Aid
offers the market a solution that meets regulatory requirements without sacrificing performance. By combining such innovations with Dow's global supply capability and local technical support, we are committed to helping packaging customers move forward steadily and continue to succeed in a constantly changing market environment."
Key features and benefits of DOWSIL™ 5-1050 Polymer Processing Aid
DOWSIL™ 5-1050 Polymer Processing Aid is designed for a wide range of film applications and resins. It uses polyethylene as a carrier with a silicone component added. The product is supplied in masterbatch form, making it easy to use directly in existing extrusion processes. The technology has been validated at industrial scale and performs reliably. Key benefits include:
Reduced melt fracture and film haze: enhances film surface smoothness, improving clarity and visual texture.
Reduced die build-up: lowers downtime frequency and reduces waste generation.
Lower die pressure: improves extrusion efficiency.
Food-contact safety: complies with the requirements of regulations such as EU 10/2011 and US FDA 21 CFR 174.5.
Flexible addition methods: can be dry-blended or melt-blended with LLDPE resin.
Supporting safer, scalable packaging production
Drawing on decades of experience in compounding, extrusion and the introduction of silicone additives into plastic systems, Dow is committed to developing innovative solutions that can help the packaging industry transition to safer, more sustainable materials.
DOWSIL™ 5-1050 Polymer Processing Aid
is now available in sample and production-scale quantities.
