Phase change Insulation

Hi

I wonder if anyone has used a phase change Insulation. eg http://www.phasechange.com.au/casestudybiopcm

In discussion with my sister (physicist with phD) the physics of the material is sound, but not sure if the practical application is good?

TIA

quigly

I am familiar with the physics, having done it at school. It works.

The material data sheet on this one does not show the flammability, which I suspect is very high, as it seems to be a fat or oil substance inside the waffle - which is exactly what we did our experiments with at high school. And you can't use water to extinguish it. Excellent at storing and stabilising heat, but unfortunately not my idea of a safe product. (And very expensive for a wax/oil base @ around $36/kg of wax). The equivalent of filling your walls with kero...???

SECTION 2 - COMPOSITION/INFORMATION ON INGREDIENTS

Ingredients and Components: Derivatives of Fatty Acids, Fatty Alcohols, Esters, Emulsifiers,
Thickening Agents and proprietary Cross linkers.

SECTION 5 - FIRE FIGHTING MEASURES

• Extinguishing media:
 SMALL FIRES: CO2 or dry chemical
 LARGE FIRES: Foam
• Unsuitable extinguishing media: Water spray may be ineffective on fire.
• Explosive limits in air:
 Upper: Not available
 Lower: Not available
• Special Protective Equipment: Wear self-contained breathing apparatus and full protective
clothing.
• Other Fire Fighting Considerations: Cool containers with flooding quantities of water until
well after fire is out.

SECTION 9 - PHYSICAL AND CHEMICAL PROPERTIES

[*]• General Information:
 Physical State at 25
o
C: Soft Gel
 Density: 0.8-0.9
 Appearance: Semi Transparent
 Odor: Neutral
 pH: Not applicable
 Flammability (solid, gas): Not available
 Boiling point: >480° F (249° C)
 Oxidizing properties: Not available

Just ordinary "state" change as to solid liquid gas.

Different, but it sounds a bit risky for the material.
