Dow has announced the launch of new generation low cyclics, low volatile silicone surfactants. The additives will support innovative rigid polyurethane foam formulations address key energy efficiency and sustainability trends in the cold chain appliances.
Dow’s New Portfolio of Silicone Surfactants:
VORASURF™ RF 5374 Additive achieves 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.
VORASURF™ SF 2937 Additive supports enhanced k-factor in pour-in-place, continuous panel, closed-cell spray polyurethane and polyisocyanurate (PIR) insulation foam, suitable for use with a variety of traditional and more sustainable blowing agents (HC, HFO, HFC and water-blown systems).
Innovations to Meet Demands for Sustainability
The 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. “
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,” said Justin Weare, North America marketing manager for polyurethane additives at Dow.
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 register online.
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.
