| TECHNICAL DATA SHEET FOR HiTHERM HT-450 | ||
|
HT-450 is a rigid, closed cell polyisocyanurate foam that provides exceptional insulating value at continuous operating temperatures of +400° F (202° C), with intermittent service to +450° F (230° C). HT-450 offers operators improved energy conservation due to increased insulating efficiency, better process controls and yields, while providing upgrades in strength, durability, stability, moisture resistance and a low installed cost. It is also available as a liquid system for use in pre-insulated pipes and "in situ" applications. HT-450 can also be made available as bun stock in limited sizes. The physical and chemical properties of HT-450 are shown below. |

| * · The physical properties shown above were obtained by processing the chemicals through a conventional low pressure high shear mixing machine. Chemical temperatures were maintained at 90° F (32° C) for the isocyanate component and 80° F (27° C) for the polyol. Box pours measuring 24" x 24" x 24" (61cm x 61 cm x 61 cm) were made and the resulting foam was cured for 30 days at room temperature, approximately 77° F (25° C). Testing was done on core samples cut from the box pour. | ||
