<P>The <STRONG>Thermo heating foils</STRONG> are made from flame-retardant polyester foil with a silicon protective paper and one self adhesive face. They are suitable for application to all surfaces and are cut and rupture resistant. These quality products protect surfaces, equipment, housings, circuits, even various fluids against freezing temperatures safely. They are not thermostatically controlled and should not be operated continuously without a suitable thermal regulation system in order to prevent overheating and possible damage.</P><P></P><P>The specified surface temperature corresponds to a mean value with an ambient temperature of 20 °C (45% r.H.) in still air. The target heating temperature is extremely dependent on external influences such as the presence and type of substrate, thermal insulation, ambient temperature, air flow, humidity, operating voltage and tolerances. </P>
