Dow launches a silicone-based alternative to fluoropolymer processing aids for film packaging

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 growing market demand for fluorine-free polymer processing aid film packaging solutions. This product is a silicone-based processing aid that can replace traditional fluoropolymers, and it also performs well in reducing melt fracture and reducing die buildup in linear low-density polyethylene (LLDPE), helping to produce high-quality films.

Reliable silicone-based polymer processing aid meets evolving industry needs

"For a long time, fluoropolymer processing aids have performed well in most film applications and other processes," said Mubashir Ansari, Technical Service and Development Scientist at Dow. "As these fluoropolymer-based solutions gradually exit 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

provides the market with a solution that meets regulatory requirements without sacrificing performance. By combining such innovations with Dow's global supply capabilities and local technical support, we are committed to helping packaging customers move forward steadily and achieve continued success in a 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 silicone components 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 consistently. Key benefits include:

Reduced melt fracture and film haze: enhances film surface smoothness, improving clarity and visual quality.

Reduced die buildup formation: lowers downtime frequency and reduces waste generation.

Lower die pressure: improves extrusion efficiency.

Food-contact safety: complies with 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, scaled-up packaging production

With decades of experience in blending, extrusion and the introduction of silicone additives into plastic systems, Dow is committed to developing innovative solutions that 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.
