Flexible Heating film: Flexible heating film
273 Langston Road Piedmont, SC 29673 United States of AmericaContact: Marc Burnham (mburnham@thermo-llc.com)
A range of thin, flexible heating surfaces that are deposited by screen printing. Various types are available: Fixed Resistance on PET Film - highly flexible film, compatible with a wide range of applications. Most size, shape, wattage and voltage requirements can be met using this technology; Positive Temperature Coefficient (PTC) on PET Film - primarily incorporated in automotive applications, this system regulates its own wattage output according to temperature; Continuous Web on PET Film; Ultraflex™ Fabric Heater – these heaters are manufactured using a special fabric which is extremely flexible, light and remarkably soft;Thermofol® Water Resistant Heaters - By encapsulating standard PTF heaters, they are ideal for application in moist or wet environs. There is also available: Fixed Resistance on PEN Film - The flexible substrate polyethylene naphthalate is used when an increase in operating temperature is required. With a 160°C (320°F) RTI, it is a cost effective film with performance between that of polyethylene terephthatlate (PET) and polyamide films. Applications for these heaters include automotive (de fogging of rear view mirrors), medical (blood bottle storage), and industrial (tempering milking stations)

Thermosiv Heating Fabric: Heated woven textile
Jakob-Klar-Str. 10a 80796, München, GermanySample Contact: Chaim Ashar (ashar.id@t-online.de)
Heated woven textile, that combines electrically non-conductive (polyester) and conductive (polymer matrix with carbon fibers) yarns. The material is very efficient in converting electricity into heat; it can be heated up to 120°C and is flexible, breathable, washable, thin and lightweight. These woven resistors can be operated with various power sources (rechargeable batteries (3.6V+), 110/220V and 12/24V and solar cells). The material can be torn, perforated and sewn without creating a short circuit. Possible applications are for automotive design, interior design (also heating), medicine and sport clothing.

Thermion Heating Pad: nickel plated carbon filament non-woven conductive textiles
55 Old South Avenue Stratford, CT 06615 United States of AmericaContact: Jeffrey R. Parkin (203) 377-3770
Year Introduced: 2002
Non-woven electrical and heat conductive textiles that produce even heating over a large flat surface. The non-woven textile is manufactured from flexible nickel coated carbon fibers that are formed together using a paper making process. The fabric may be laminated within a range of materials including thermoplastic, thermoset, elastomeric or composites as appropriate to the environmental conditions of the application. The textiles are capable of reaching temperatures of over 1000ºF (538ºC), however, the heaters are typically used in the range 120–350ºF (49-177ºC). The heating pads may be sized from 1 square inch (6.5 cm2) up to 10 ft2; 0.93m2 with no loss in heating intensity or speed over the entire sheet. Current applications for these heating pads are for food processing equipment as well as for pipe, bin and tank heating in industrial situations.
