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

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 temperatu...

More Information
Summary: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.
