HT-303 Polyisocyanurate Insulation
HT-303 is a rigid closed cellular 3# nominal density polyisocyanurate that is manufactured in buns for fabrication into a variety of shapes and sizes that include, but are not limited to: piping, fittings, valves, curved-side-segments and many others.
HT-303 is the industry leading polyisocyanurate when it comes to k-factor. When you are talking insulation, thermal efficiency is at the top of the list for performance. HT-303 has a k-factor of 0.172 BTU-in/hr-ft2-°F aged 180 days @ 75°F. The compressive strength of HT-303, 55psi parallel to rise, makes it a great choice for saddle supports and other areas where compression resistance is needed.
