*Dow has developed copolymer polyols (also called polymer or grafted polyols) to enhance foam load-bearing capabilities and firmness, enabling customers to produce foams with improved durability, support and comfort. Additionally, these polyols provide a highly costefficient method to improve load-bearing and creep properties for foams and elastomers compared to base polyols. They offer the advantage of “opening” the foam for easy processing and also meet customer demand for low-VOC and low-viscosity options.

Hydrophobic Polyols

Product	Functionality	OH	MW	Viscosity (cSt)	Water
VORANOL B-2000	-	54-58	2000	230	0.04
VORAPEL D-3201	-	53-59	2000	470	0.05
VORAPEL T-5001	-	280-300	600	330	0.05

*Hydrophobic polyols offer a superior combination of hydrophobicity, performance and processability when compared with polyols of similar hydrophobic character. They help to meet more stringent requirements in a variety of high-end applications for adhesives, sealants, elastomers, roof coatings and electronic potting. They contribute to an improvement in moisture vapor transmission resistance, while maintaining tensile strength, tear strength, flexibility and UV resistance. A very low TG enables use over a broad temperature range.
