Thanks to the use of special conductive inks or pastes printed on polyester sheet, ALPER is in a position to produce resistors in many shapes and very reduced thicknesses (generally 0.2 mm) to suit the specifications of the end product. The inks, that have been developed by our Company, in some particular conditions may show PTC features (Positive Temperature Coefficient) this means that they are able to limit the heat produced, with no need to apply a thermostat and with no risk of overheating. This type of resistor offers many advantages when compared with the more traditional electrical resistors now on the market. The particular features of PTF heaters make them so versatile that they can be employed in a wide range of applications in both the domestic and industrial sector. ALPER is currently producing, using its resistors, some end-products such as aquarium heaters, appliances for beauty treatment, de-misting sheets for mirrors, towel warmers, heating mats for ‘terrariums’ and heating elements for propagators. ALPER develops and produces PTF type resistors also in co-operation with Customer Companies, such as manufacturers of small domestic appliances, hot-plates, food warmers, trouser presses, etc., thanks to the support of its design and engineering department.
