Ketong graphene electrothermal film

The surface material of graphene electric heating film is a special polyester film
The ink line in the middle of the film is conductive ink, which is the core part of the electric heating film, which is equivalent to many parallel resistors and can generate heat after power on
The silver strips on both sides of the electrothermal film are metal current carrying strips, which are used to connect graphene nano carbon (resistance) and act as wires
The main materials of metal current carrying strip are copper tin plating and silver paste

Performance characteristics
High voltage resistance:
Graphene electric heating film can withstand the test voltage of more than 1500V without damage
Anti aging:  
The materials for making graphene electrothermal films are made of special materials
They have good characteristics, anti-aging, no deterioration, stable performance and long life
nbsp;
Moisture resistance:
Graphene electrothermal film at 50 ℃ & plusmn; 5% in a container with relative humidity of 80% - 90% for 500 hours
Take out the test, the resistance does not change, and the insulating layer is not damaged
High toughness:
According to the test, the tensile resistance of the electric heating film is 20kg
Small shrinkage:
In the 2000 hour aging test, the shrinkage was less than 2%
Stable performance:
After testing, the electrothermal film runs continuously for 2000 hours at 85 ℃, and its performance and size remain unchanged
Sufficient heat sealing:
Advanced heat sealing technology makes the diaphragms fully polymerize without bubbles and layers, so as to ensure the close combination of heating body and current carrying strip
Wide tolerance:
Graphene electrothermal film can operate safely at - 40 ℃ - 100 ℃
After testing: the electric heating film is repeatedly bent and stretched in the environment of - 40 ℃, without fracture, and still maintains its soft and durable performance
Advanced technology:
Ketong adopts fully automated production equipment and exclusive graphene nano carbon formula, and the product remains stable for 50 years
Good security:
The surface temperature of graphene electric heating film after power on shall not exceed 55 ℃ at most, and it shall not spontaneous combustion, self explosion and electric leakage
Harmless to human body:
The infrared peak wave of radiation is 7-15 microns, which belongs to far infrared and is beneficial to human health
