Polyurethanes

Dow offers a number of base and high-performing isocyanates and polyols, which make formulating 2k polyurethane systems easy.  With their wide range of products, you can easily formulate:

• Coatings, adhesives, sealants and elastomers
• Low- and high-density semi-rigid foams
• Rigid foams
• Viscoelastic (memory) slab foam
• Structural reaction injection molding (RIM) materials
• Flexible molded foam and slabstock

Dow’s Isonate™ MDI line provides pure methylene diphenyl diisocyanate (MDI), one of the most crucial isocyanates used for manufacturing rigid polyurethane foams. These foams find extensive use in construction, refrigeration, and other applications that require rigidity.  

Complementing the pure MDI offerings, Dow's PAPI™ polymeric MDI products are blends of monomeric MDI and polymeric MDI molecules, offering enhanced flow properties compared to pure MDI. These polymeric MDI blends are particularly suited for rigid foam insulation in construction and cold chain applications. 

At the forefront of Dow's offerings is the renowned VORANOL™ line, comprising polyether polyols synthesized through the reaction of epoxides, such as ethylene oxide or propylene oxide, with initiators like glycerine. These versatile polyols find extensive application in the production of flexible, semi-rigid, and rigid polyurethane foams, catering to industries as diverse as furniture, automotive, and insulation. Prominent examples within this line include VORANOL™ 490, VORANOL™ 800, and VORANOL™ 921, each tailored to meet specific performance criteria. 

From footwear to mattresses, automotive interiors to rigid foam insulation used in refrigerators and construction, these essential additives allow you to optimize your system, solve problems and develop innovative products for your customers.
