MOSCOW (MRC) -- Huntsman Corporation has announced that three of its Terol performance polyols from its Polyurethanes Division have received Underwriters Laboratories (UL) Environment certification, reported GV.
Terol 250 and 649 polyols received inaugural certifications, and Terol 563 polyol was re-certified to reflect increased recycled content. Huntsman Polyurethanes says it became the first US aromatic polyester polyol manufacturer to receive the designation in 2014.
"Huntsman is committed to providing high-quality, sustainable materials that allow our customers to design their insulation products with confidence," said Les Yamato, Business Manager, Terol Polyols, Huntsman Polyurethanes. "Receiving UL Environment recognition for Terol 250 and 649 polyols is an important step, as we now offer certified systems house polyols in addition to our primary product used in polyiso boardstock applications."
Terol 250 polyol contains an average of 64% recycled content, consisting of 36 % post-consumer and 27 % pre-consumer recycled material. It is recommended for use in all polyurethane and polyisocyanurate systems, as well as spray foam and pour-in-place applications. According to the manufacturer, the high aromatic content and lower viscosity of Terol 250 polyol allows for the use of lower flame retardant levels with good viscosity and fire performance results in finished B-sides, in small scale testing.
Terol 649 polyol is Huntsman’s newest product for systems house applications. It contains an average of 16 % bio-based material and 24 % pre-consumer recycled material, and is targeted for use in next-generation blowing agent systems, but can also be used with hydrofluorocarbons (HFCs), such as 245fa or 365mfc/227. The high functionality of Terol 649 polyol allows for higher loading levels of the polyester, up to 100 % of the polyol requirement. This can improve the performance of spray applied polyurethane foams in an array of testing protocols, particularly small scale fire testing, and can allow reductions in the amount of flame retardants required in the B-side of the formulation.
Terol 563 polyol has been re-certified, increasing from 27 to 32 % recycled content, and is primarily used in polyisocyanurate boardstock insulation applications. When properly formulated and processed, insulation panels produced with Terol 563 polyol can pass the Factory Mutual 4450 Calorimeter and ASTM E-84 Tunnel tests, says Huntsman.
UL verified Huntsman’s pre-consumer recycled, post-consumer recycled and renewable resource content claims by reviewing the company’s manufacturing practices and raw materials sources. Huntsman says it is working to secure certification for additional polyols, which allows customers to design their insulation products with confidence and meet preferred purchasing protocols. The company says it offers one of the broadest ranges of aromatic polyester polyols for rigid foam applications, with hydroxyl values ranging from 120 to 350. Additionally, its customized polyol solutions can meet the most demanding insulation applications, says Huntsman.
As MRC wrote before, in October 2014, Huntsman Corporation completed the acquisition of the Performance Additives and Titanium Dioxide (TiO2) businesses of Rockwood Holdings, Inc. And in February 2015, the company announced that it planned to reduce its European TiO2 capacity by approximately 100,000 tons, representing 13% of Huntsman's European TiO2 capacity.
