ISO-HT For Higher-Temperature Applications

20130722 dyplast 0068b
ISO-HT™ is Dyplast Products' 2.5 lb/ft³ polyisocyanurate rigid, closed cell, foam insulation for higher temperature applications up to 350°F (177°C), with intermittent exposure up to 375°F (190°C). ISO-HT is suitable for constant temperature or heat cycling environments. ISO-HT is certified by independent laboratory to meet demanding Class 1 flame spread and smoke development requirements per ASTM E84. Dyplast Products offers ISO-HT as bunstock or as sheets and blocks, with tolerances up to 1/32 inch on surfaces. Our extensive network of fabricators can provide special shapes for pipe, fittings, vessels, or other mechanical applications.

Polyisocyanurate exhibits the highest R-factor (insulating value) to thickness ratio of commercially available insulation. Ideal for applications over a wide range of temperature, from cryogenic liquids to low-temperature steam, ISO-HT offers superior performance when compared to fiberglass, mineral wool, polystyrene, polyurethane, fiberglass, and cellular glass alternatives.

iso-ht-pvc-jacketCAUTION: Severe degradation of the foam can result if water gets into the insulation system on a high temperature pipe. These include accelerated degradation and extensive charring, and loss of insulation performance. Thus it is critical that the jacketing and joint sealers are designed and installed correctly to prevent water ingress.
