New generation silicone additives support more sustainable polyurethane foams for cold chain

  • Help achieve higher energy efficiency and enhanced aesthetics
  • Facilitate transition to alternative, more sustainable blowing agents

MIDLAND, Mich. – Dow (NYSE:DOW) announces new generation low cyclics, low volatile silicone surfactants supporting innovative rigid polyurethane foam formulations addressing key energy efficiency and sustainability trends in the cold chain appliances

“Our innovations address strong industry demands for additives and surfactants supporting customers to achieve emerging performance, sustainability, and profitability challenges in the rigid polyurethane foam space,” said Justin Weare, North America marketing manager for Polyurethane Additives at Dow. “We continue to expand our industry-leading portfolio of polyurethane additives, combining unrivaled polyurethane knowledge, technical customer support capabilities, and the strongest silicone chemistry history in the industry.”

VORASURF™ RF 5374 Additive the formulator’s choice achieving high polyol side solubility, blend stability and clarity, when complex cabinet design requires enhanced flow and good aesthetics in applications demanding high insulation performance, such as cold chain, commercial and domestic refrigeration appliances.

VORASURF™ RF 5382 Additive brings improved system compatibility to help maximize the insulating performance of pentane-blown rigid foams, helping address challenging energy efficiency criteria in cold chain appliances and installations.

VORASURF™ RF 5388 Additive helps formulators meet essentially all desired properties of appliance foam systems, with higher pentane solubility, excellent flow and exceptional surface aesthetics to avoid liner defects in domestic or commercial refrigerators and freezers.

Rossella Riccio, development scientist for Polyurethane Additives at Dow, will present the specifics of these novel silicone surfactants and showcase their performance attributes in rigid polyurethane foam applications during a dedicated webinar on Wednesday, July 16 at 10 a.m. Eastern Time. Interested participants are invited to view the replay.

These innovations come in addition to Dow’s portfolio of leading silicone surfactants for rigid foams, which include grades recognized as a global industry standard: VORASURF™ DC 5604 Additive, VORASURF™ DC 193 Additive, and VORASURF™ DC 5357 Additive.

Dow has been working together with the polyurethane industry for decades, offering formulators with a wide portfolio of solutions, including silicone performance additives, surfactants, and release agents.
