Huntsman Corporation has announced that its Polyurethanes Division introduced TEROL 649 aromatic polyester polyol, a high-functionality aromatic polyester polyol developed for rigid foam systems, particularly spray polyurethane foam (SPF).
TEROL 649 polyol features enhanced solubility, improved fire performance and compatibility with new blowing agents, while also reducing the needed amount of polyether polyols and flame retardants. It can also reduce or completely eliminate the use of brominated flame retardants (BFRs), one of the most widely used flame retardants in the market today.
“With its high performance, TEROL 649 polyol adds a great new product to our already expansive line of energy-saving aromatic polyester polyols,” said Les Yamato, Business Manager, TEROL Polyols, Huntsman Polyurethanes. “This enhanced polyol allows our customers to design their insulation products with confidence.”
TEROL 649 polyol can be used with 3.5 and 4.0 generation blowing agents. Additionally, it can be used with
HFC-245fa and other hydrofluorocarbon systems. TEROL 649 polyol allows for higher loading levels, up to 100 percent of the polyol requirement, which can improve the performance of SPF in an array of testing protocols.
With hydroxyl values ranging from 120 to 350, Huntsman offers one of the broadest ranges of aromatic polyester polyols for rigid foam thermal insulation applications. Additionally, Huntsman’s polyol solutions can be tailored to meet customer specifications across the insulation value chain, including boardstock, SPF, insulated metal panels, structural insulated panels, appliances and commercial refrigeration.
