Technical Bulletin 0714 Elastomeric Insulation versus Polyisocyanurate in Low Temperature Applications

This Technical Bulletin is another in Dyplast's series to provide objective information to decision-makers and end-users on important issues related to mechanical insulation (i.e. insulation for equipment).

PURPOSE 

Several of Dyplast’s prior Technical Bulletins have provided in-depth comparisons of various insulants, including polyisocyanurate (polyiso or PIR), polyurethane (PUR), phenolic, polystyrene (expanded EPS and extruded XPS), cellular glass, and fiberglass - - as well as less-than-comprehensive comparisons with elastomeric and aerogel. Now with somewhat more information becoming available from elastomeric manufacturers and the aggressive marketing from elastomeric suppliers for colder applications it is appropriate to dedicate a Technical Bulletin to elastomeric insulants as compared to polyisocyanurate - - and to a much lesser extent phenolic, and cellular glass.

QUICK PERSPECTIVES

The most basic perspective is that the overall cost of elastomeric insulation is materially higher than polyisocyanurate, and polyiso also has significantly better thermal insulation properties - - thus raising the question of "why use elastomeric"
