Electrically Heated Coating
The electrical heating solutions of FutureCarbon are
based on the principle of resistive heating, also referred to as ohmic
or joule heater. The amount of current flowing at a given voltage is
related to the electrical resistance of the conductor to its passage. By
applying an electrical voltage to a resistor and implying a current
flow, energy is transferred into the resistor. Hereby, the electrical
energy is directly converted into thermal energy, i.e. heat.
Resistive heating causes a thermal
radiation which causes a sun like feeling of warmth. Radiation heat
directly warms up people and objects, rather than warming the
surrounding air as done via convectional heater. This effect makes it an
excellent and highly efficient choice for task specific spot heating
applying the heat where it is really required.
The electric heat can be accurately
applied at the precise point needed in a process, at high concentration
of power per unit area or volume. Electric heating processes are
generally clean, quiet, and do not waste energy by warming up
surroundings to achieve the same results.
FutureCarbon designs polymer systems
with high electrical conductivity characteristics utilizing the
excellent conductivity of carbon materials. A defined combination of
different carbon materials is dispersed most homogeneously into an easy
to apply, aqueous matrix system such as polyurethane, acrylic, etc.
The result is a new composite solution
for electrical heating where the carbon material acts as the conductor
in the matrix while the polymer is electrically isolating. Radiation
heat is generated at the carbon-polymer-interfaces once a current
flowing through the composite material is applied. The efficiency of our
solutions converting the electrical to thermal energy is almost 100%
Through material excellence and
patented processes FutureCarbon is in the position to precisely tune the
electrical resistance of the polymer matrix and thus, able to address
all voltage levels, e.g. from 12V up to 230V…or higher.
The solutions offered today are
covering a very broad temperature range up to industrial temperatures of
500°C. with the maximum temperature actually defined by the melting
temperature of the respective polymer.
