An article comprising a heater that comprises a high-resistance magnification (HRM) PTC ink deposited on a flexible substrate to form one or more resistors. The HRM PTC ink has a resistance magnification of at least 20 in a temperature range of at least 20 degrees Celsius above a switching temperature of the ink, the resistance magnification being defined as a ratio between a resistance of the double-resin ink at a temperature 'T' and a resistance of the double-resin ink at 25 degrees Celsius.

Thermal substrate with high-resistance magnification and positive temperature coefficient ink

A positive temperature coefficient (PTC) composition having a first thermally active polymer having a melting point of 30-70&#xb0; C. and providing a first PTC in a lower temperature range below 70&#xb0; C., and a second thermally active polymer having a melting point of 70-140&#xb0; C. and providing a second PTC in a higher temperature range above 70&#xb0; C., the composition also having conductive particles; and an organic solvent with a boiling point higher than 100&#xb0; C., solvent being capable of dissolving both the first and second thermally active polymer.

Electrically conductive PTC ink with double switching temperatures

An article comprising a double-switching heater that comprises a double-switching PTC ink deposited on a flexible substrate to form one or more resistors. The double-switching PTC ink comprises a first resin and a second resin; the first resin provides a first PTC effect within a first temperature range (T1, T2); the second resin provides a second PTC effect within a second temperature range (T3, T4), where T3&#x2265;T2; the first resin has an NTC effect above the first temperature range; the second PTC effect is greater than the first PTC effect; and the second PTC effect overlaps with, and is greater than, the NTC effect of the first resin. The substrate can be either thermal polyurethane, nylon or a polyester blend.

Electrically conductive PTC ink with double switching temperatures and applications thereof in flexible double-switching heaters

A printed circuit that comprises a substrate, electrical interconnects and a double-resin ink having a positive temperature coefficient (PTC), wherein the double-resin ink has a resistance magnification of at least 20 in a temperature range of at least 20 degrees Celsius above a switching temperature of the double-resin ink, the resistance magnification being defined as a ratio between a resistance of the double-resin ink at a temperature 'T' and a resistance of the double-resin ink at 25 degrees Celsius. The substrate is a fabric or mesh, while the double-resin ink and the electrical interconnects are deposited onto the substrate.
