Overview of the heating film

The XiCA heating film is comprised of a carbon-heating element applied to the Base Film with an insulator and fire retardant, with the activated carbon or pollutant absorber covered. It is the cutting-edge far IR surface phase heating element laminated with PET film after the electrode is manufactured with thin copper. Unlike other heaters, the carbon-heating element applied to the entire film emits far IR radiation, creating warmth like the sun. The film heater is equipped with special PET fabric as the external material, specially treated to prevent contact between the heat and the wall, ceiling and floor heating materials, with semi-permanent life. The performance of the heating film is enhanced by nano-particle technology through the adhesion and resistance of carbon and silver particles.
Effect of the XiCA heating film
  1. Radiation heating by far IR
    - Rapid heating
    - Warmth with no indoor temperature differences due to far IR
    - Fresh heating at relatively low temperatures compared to convection heating
  2. Easy installation and operatio
    - Easy installation compared to working with wet mortar
    - Installing between the floor finish and heat insulator completes installation
      [* Requires course on heating film installation prior to installation]
  3. Excellent durability
    - Semi-permanent use
    - Simple structure and fewer malfunctions
  4. Heating with no combustion
    - Heating with no flame, carbon monoxide, dust and combustion noise
    - Good for facilities for children, seniors and patients
       (Kindergarten, daycare center, senior center, hospital)
  5. Silent and clean heating
    - Emits large amount of far IR and negative ions by heating carbon
    - Far infrared / negative ions remove indoor odors,
      are very good for the human body, and freshen indoor air
  6. Excellent cost-effective heating
    - Lower than electric heat and oil boiler by 30% and 60%, respectively
    - Saves costs by reducing the time needed for installation
    - Partial heating and energy-saving
    - Introduces automatic control (central heating)

Carbon black as a component of the XiCA heating film [Carbon black]

Carbon black is a material mainly composed of carbon (C), similar to diamond, and is used in automobiles, inks and cosmetics.
Carbon fiber is produced at 1400 - 3,000°C while graphite fiber is produced at temperatures higher than 2,500°C. Graphite has a very high heat resistance and very small heat expansion coefficient compared to other materials, imbuing it with excellent heat conduction and electrical conductivity. Graphite is therefore a widely used material for electrical heating elements.
* The adhesiveness and resistance of the product may be varied depending on the mixture
  of carbon and graphite, which serves as the heating part of the film. (This utilizes the circular
  molecular structure of carbon and the plate structure of the graphite)
Silver Paste
-Silver paste, the conductive material in the XiCA heating film, is a low-temperature conductive paste used in the surface phase heating element. It provides high conductivity and excellent screen printing, flexibility and adhesiveness of the PET and Laminex.

Durability Test of Heating Film
  • Experimental Institute : US AIC TECHNICA
  • Experimental Period : April 25~May 22, 2009.
  • Experimenter : Dr.Martin Peacoak (Director of Biotechnology and Materials Science)
    Test 1. Conduct of Durability Test for Overvoltage and Over Heating
    Durability test conducted by supplying voltage of 480v (exceeding designed power consumption by 23 times)to XICA Heating Film designed for 110V AC for about 30 minutes.
XICA 205e model (designed power consumption 400W/m2 ) Used film heater for high temperature to generate high heat.
after 10 minutes(film surface temperature 148.9°C, The film begins transformation and generates bubbles.)

after 17 minutes (film surface temperature 165.5°C, wrinkles on the film surface occur and spread out.)

after 23minutes (film surface temperature 171.1°C, The film starts to shrink.)

* XICA Heating Film has passed the durability test for sales in U.S. market by enduring the voltage of 480V (exceeding designed power consumption by 23 times) for 30 minutes and demonstrating heat-resisting force of about 170°C in above experiment.
Test 2. Test for Estimating Product Life Span
Check surface cracks of carbon heating element after testing repeatedly the following experiment for 24hours :
  • Operate XICA Heating Film for 20minutes,
  • Keep its film surface temperature at 40.5°C,
  • Lower its film surface temperature to 0°C through the power block and rapid cooling.

translucent film : for insulation and flame-retardant
transparent film : for normal display
hardening check if film surface is uneven.
Copper Foil Booth Bar copper foil width foil is, The more current is allowed when applying electric current.
copper foil thickness the thinner copper foil is, the less spark occurs to avoid widening gap between copper foil and film.
type of copper foil Electric conductivity : tough pitch copper (pure copper) : 106%
Phosphorus-deoxidized copper : 86%
Dopping even carbon surface Check surface with more than 10 times magnifying glass.
spark-resistant design When suffering overload on carbon printing surface, check if design reflects structure to prevent sparks.
silver surface When measuring electrical resistance of silver surface to prevent sparks, the lower resistance, the safer. (Ideal below 1-ohm)
Precaution of Installation
  1. Clean the floor of the construction site before installing. Even the floor in order to prevent the heating film from bending or curving.
  2. Eliminate construction site's all moisture and dampness in order to prevent them from touching the film.
  3. Do not use glass fiber or heat insulator with ragged surface to prevent the damage on film's surface.
  4. Be careful neither to damage the surface of film nor step on it when installing them.
  5. For finish material, do not use paints that changes color or makes cracks when heated, coloring agents or hardening adhesives.
  6. Consult with specialist or construction contractor when installing heat insulator or finishing materials in order to maximize the heating efficiency.
  7. When cutting the film, make sure that length of the film do not exceed specified capacity of power consumption(Watt) and thermostat.
    * Formula : Watt = V2R (V=Voltage, R=Resistance)
  8. Consult with construction specialist or construction contractor for each construction site when installing other kinds of films.
  9. Please add 20% to the minimum expected heat rate when installing after considering various external environments, uses, and other environmental condition

RexVa has a goal to change heating system of the whole world into heating film and try to make our living warm by means of spreading Korean Ondol culture to the world. XiCA heating film made by spreading Carbon heating element on PET film. PET film is a insulation and fire retardant material to 120℃ manufactured by using safe materials. The success of mass production for new product PTC Heating film and export. PTC(Positive Temperature Coefficient) is a product controlling the temperature itself by heating environment of Carbon heating materials. When the temperature increases, the resistance value increases. Therefore, it can control the current and electricity and make the heating amount down for no overheating and power consumption down as a third generation heating film. However, the PTC heater prevents that High temperature may rise depending on the nature of the particular part of the environment. XiCA Heating Film is outstanding for shock, waterproof, and dustproof. Using Pet Film of insulation and fire retardant lead to the safe product and the excellent durability to 120℃. PTC Heating is able to meet another consumer’ s need. XiCA Heating Film has been loved for the floor heating and you can check its application as follows.
