Excellent Thermal Performance: HITLIN™ E-glass can dramatically reduce heat loss (49% less compared to Calcium Silicate) in hot equipment and piping applications because of its exceptionally low thermal conductivity.


Excellent Dimensional Stability

The “water absorption test” was performed on three industrial insulation samples. The products tested were Calcium Silicate, Perlite and RCUI 99.7% water resistant HITLIN™ (High Temperature-Layered-Insulation).
Each sample consisted of a 2-inch square block of the subject material. The blocks were dry and weighed before placing them into individual beakers of water. The rate of water absorption was observed. The test lasted ten (10) minutes. Samples were re-weighed after testing then allowed to “dry out” for 18 hours. At that time, the samples were re-weighed then, placed in an oven that was set to 500°F. After one (1) hour, the samples were pulled from the oven and weighed one final time. Observational results are provided in the following table.

Water resistant HITLIN™ has a much higher resistance to water than Calcium Silicate or Perlite. HITLIN™ sample dries out much faster than other samples when put back into service after water exposure. Long term water retention in Calcium Silicate and Perlite would negatively affect thermal conductivity of those products. HITLIN™ performance is significantly superior to other samples when exposed to water .
