| Material and Mechanical Properties of Polar Insulation
Corrosion Resistance :
The
naturally occuring surface oxide on all aluminium in the presence of
atmospheric oxygen acts as a shield and renders foil substantially
corrosion resistant. Polar Insulator is also resistant to substances in
the pH range 4 to 9.
Reflectivity :
Reflects
approximately 99% of radiant heat and light. There is no difference
between the reflectivity of a bright and a matte polar Insulator
surface.

Barrier Protection :
A
Layer of Polar acts as a complete barrier against the penetration of
light, moisture and flavours - so stopping contamination and the loss
of organoleptic characterstics.
Heat Performance :
Polar
Insulator withstands high temperatures without distorting or melting.
It also conducts and dissipates heat quickly - ideal for heat - sealing
processes. |
