The “water absorption test” was performed on three industrial insulation samples. The products tested were a pink Calcium Silicate, a blue Calcium Silicate and RCUI 99.7% water resistant HITLIN™ Industrial Insulation (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.

A comparrison

Water Test
	Pink Calcium Silicate	Blue Calcium Silicate	HITLIN™ Industrial Insulation Industrial Insulation
Pre-test weight, dry (grams)	41.1	42.8	32
Weight at end of water soak	182.2	159	64.6
Weight, 18 hours later	175	155	60
Weight after oven drying	85	75	32



1. All three samples floated at beginning of the test. The blue Calcium Silicate sample sank to the bottom of the beaker in 2 minutes. The pink Calcium Silicate sample sank to the bottom of the beaker in 9 minutes 10 seconds. The test was suspended after 10 minutes. The HITLIN™ Industrial Insulation sample was still afloat.


2. When samples were pulled from water, both Calcium Silicate samples left the water discolored with residue that dissolved from the samples.


3. The Calcium Silicate samples became completely saturated with water and sank. Their weights increased by a factor of four (4). HITLIN™ Industrial Insulation weight went up by only half that amount.


4. After one (1) hour of oven drying at 500°F, the HITLIN™ Industrial Insulation sample completely dried out while the Calcium Silicate samples still contained twice their weight in water.


5. After one (1) hour of oven drying at 500°F, the HITLIN™ Industrial Insulation sample completely dried out while the Calcium Silicate samples still contained twice their original weight in water.
   

Conclusions:

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