• HT-450 is a patented product without equal. It provides continuous service at temperatures between -100° F and +400° F with intermittent service up to +450° F. This singular temperature range affords the insulation user, contractor and distributor to carry one, in lieu of many different insulation products. HT-450 finds exclusive use as a very effective insulation for steam pipes, in both above and below ground applications. HT-450 is also available as a liquid system.
