Pi heating pads use surface heating method, the allowable surface power density is very great, the maximum can reach 7.8W/cm2, therefore, this product series has a better heating uniformity performance, faster heating rate characteristics.
Graphene heating application product's, produced graphene far infrared is surface heating, higher density penetration of the skin texture, relieve pain.
Choose (pi heating film) polyimide heating pads or graphene heating pads, mainly depends on the application of the use of the two, although *** sex more, but because of the use of different heating materials, the scope of application, the use of the cost is also different, you need to choose from the use of the heating element of the application of the environment and the need to choose.

Polyimide heating pads cost less than the real graphene heating pads, and the applicable temperature range of the application is more extensive, the thickness also has a certain advantage, the market in the middle and high temperatures of the use of polyimide heating pads more. Graphene heating pad is actually more used in the low temperature environment, but also because of its far-infrared heating properties, more for health care or medical equipment industry.
Polyimide heating pad: polyimide heating pad, also known as FPC electric heating film, PI electric heating film, is the use of polyimide (PI or Kapton?) as an insulator, metal foil and flexible insulating materials by high temperature composite of flexible electric heating film. Among them, polyimide is flexible, thin thickness, high insulation strength, non-toxic translucent material.
Polyimide heating pad for flexible film type heater is very suitable for the use of small area and light weight needs, or the heater is exposed to vacuum, radiation, oil or certain chemicals.
Graphene heating pad: Graphene heating pad is a kind of electricity can heat the composite film, by the super conductive graphene and polyester composite made of electrically conductive composite film, set up current-carrying strips, and then covered with insulation made after the protective layer. Graphene heating pads are characterized by high heat conversion rate, high voltage resistance, low residual current, low power, rapid response time and long service life.
