What is PTC function?

PTC is made from a carbon-nano compound, The compound is produced by incorporating carbon with polyethylene resin. In this case, carbon is used electrical conductor and polyethylene is used for its properties of contraction and expansion due to heat.

When the temperature goes up in one part of PTC heating film, the polyethylene resin expands. This increases PTC’s electric resistance then the power consumption is reduced.

So, PTC heating unit is very effective and safe to prevent any partial over-heating. It also generates more heat with low temperatures and reduces the power consumption as temperature goes up. It helps you to save energy.

Even in the same space, the temperature will vary according to the different conditions of lighting, humidity, and insulation.

But, as the whole part of PTC heating film self-controls the temperature, it keeps the optimal temperature by well-distributed heat with a minimum energy. Sunny Warm self-regulating PTC heating film helps your smart and intelligent heating. You now understand why this is the most effective electrical heating system.

How to choose a good heating film

1. Carbon pattern for even heat distribution

2. Good adhesion between base film and Laminex film

3. Silver booth bar design that can deliver electricity evenly from copper foil to the carbon pattern

By reducing the thickness of the carbon paste print on the heating film and reducing the amount of silver paste to make a cheaper film, the difference in price can be US$0.30 at maximum.

However, thin carbon thickness and unstable silver booth bar can cause overheating of the heating film and cause a fire if such the heating film is used for a long time.

The carbon pattern is the same concept as the area of the heating element in heating film.

The even and wide carbon pattern means that heat is generated evenly over a large area in heating film and the heating efficiency is good.

However, if carbon is printed on the entire surface of the base film, the adhesive strength between the base film and Laminex film may be reduced. So, it is necessary to design a carbon pattern considering the adhesive strength of heating film.

The silver booth bar in the heating film is designed to stably supply electricity to the carbon pattern generating heat.

That is to say, the resistance values of carbon and copper foil are different. So, the silver booth bar with a low resistance value is printed on the carbon pattern in order to stably transfer the electricity transferred from the copper foil with a low resistance value to the carbon with a high resistance value.

Therefore, a good silver booth bar should have a concentration that makes the carbon pattern of the bottom invisible. Also, the design of a good silver booth bar should have a straight line shape to evenly supply electricity to the carbon pattern.

In addition, if the silver booth bar is positioned on the carbon paste and the copper foil is placed at the same position, the rough surface of the copper foil can damage the silver booth bar and connected directly to carbon pattern cause an electrical spark. So, the ideal silver booth bar design is that carbon pattern and the copper foil are connected by the silver booth bar at a distance from each other.

Installation Procedure of SUNNY WARM Heating Film

1. Clean up the floor of installation area

Clean up the base floor and remove dusts on base floor. If the floor is wet, it also removes moisture.

2. Cutting insulation pad & fixating

Cover the floor with insulation according to the shape of the floor. Fixate insulation pad on floor with tape.

3. Cutting heating film & fixating

Cut heating film according to the floor size and place on the fixed insulation pad.

When cutting heating film, apply cutting to the places where there is scissors shape.

Allow 10 ~ 20cm of space from the wall and minimum 1cm between each heating film.

Then, fixate heating Film on the insulation pad using tapes.

3. Cutting heating film & fixating

Cut heating film according to the floor size and place on the fixed insulation pad.

When cutting heating film, apply cutting to the places where there is scissors shape.

Allow 10 ~ 20cm of space from the wall and minimum 1cm between each heating film.

Then, fixate heating Film on the insulation pad using tapes.

4. Insulation treatment of heating film

The cut side of the heating film that does not connect electric wires is insulated with insulation tape or butyl tape. Butyl tape is a kind of insulating tape.

5. Connecting electric wires with terminals

Push a part of the pressure terminal on the copper foil part of the heating film into the empty space between the PET film and the laminex film and fix it firmly with a terminal presser."

Connect the electric wires in parallel to the terminals fixed on the heating film. Be careful not to twist the wires when connecting them.

6. Insulation treatment of electric wire connection area

Apply special insulation tape where the wire and film is connected.

When treat insulation, press the butyl tape strongly to prevent moisture from penetrating Organize electric wires using tapes.

7. Measurement of electric resistance & Calculation of electricity consumption

Measure total electric resistance of installed heating film with resistance tester.

Calculate the electricity consumption according to the formula.

8. Thermostat installation

Inspect connections of electric wire and circuit diagram of the installed heating film once again.

If there is no problem, connect the thermostat.

9. Check the temperature and Installation of finishing material

Turn on the power of thermostat ad, Check the surface temperature of heating film with infrared ray thermometer. If there are no problems, install the finishing material.
