Pi heating plate adopts plane heating mode, and the allowable surface power density is extremely high, up to 7.8W/cm2. Therefore, this product series has the characteristics of better heating uniformity and faster heating speed.
Graphene heating application products, graphene far infrared is a kind of surface heating, which penetrates the skin with higher density and relieves pain.
Choosing (pi heating film) polyimide heating sheet or graphene heating sheet mainly depends on the application purpose. Although they have many characteristics, due to the different heating materials used, the application scope and use cost are also different, and they need to be selected from the application environment and requirements of using heating elements. More heating plates. Heating plate? :smxfrp
The cost of polyimide heater is lower than that of real graphene heater, and it has a wider temperature range and certain advantages in thickness. The polyimide heating sheet with medium and high temperature is widely used in the market. Graphene heating sheets are actually used in medium and low temperature environments. Because of their far-infrared heating characteristics, they are also used in medical care or medical device industries.
Polyimide heating film: polyimide heating film, also called FPC electric heating film and PI electric heating film, is made of polyimide (PI or Kapton? As an insulator, it is a flexible electrothermal film composed of metal foil and flexible insulating material at high temperature. Among them, polyimide is a translucent material with good flexibility, thin thickness, high insulation strength and no toxicity.
Polyimide heater is a kind of flexible film heater, which is very suitable for the requirements of small area and light weight, or the occasion where the heater is exposed to vacuum, radiation, oil or some chemicals.
Graphene heating sheet: Graphene heating sheet is a kind of composite film which can generate heat when electrified. It is a conductive composite film made of superconducting graphene and polyester, plus current-carrying strips, and then covered with an insulating protective layer. Graphene heating sheet has the characteristics of high thermal conversion rate, high withstand voltage, small residual current, low power, fast response time and long service life.
Graphene heating sheet emits 9~ 12μm far infrared ray with the same wavelength as life light wave. Graphene heating tablets are mostly used to heat clothes, shoes, hats, scarves, eye patches, head massagers, waist massagers, whole body hyperthermia instruments, neck hyperthermia instruments, etc., and have the function of physiotherapy auxiliary heating.
