The graphene far-infrared heating module uses imported polymer superconducting carbon black, graphene, curing agent, additives and other mixed through special process, and the volume resistance can be adjusted between 10O·cm and 10^4O·cm. Uniform and stable resistance value, smooth and flat surface, good flexibility, softness and flexibility. The total conversion rate of effective electrothermal energy is above 98%, with superconductivity of special graphene material, the heating performance is stable. Graphene quickly transfers the heat to stable and uneven part after the heating film generates heat, ensuring uniform heating performance. The graphene heating element can generate far-infrared radiation with wavelength of 8µm-15µm, directly penetrate the skin and subcutaneous tissues, act on blood vessels, promote blood circulation, stimulate cell vitality, regulate endocrine balance, improve immunity. Specification: Name: Graphene Heating Insole Size: about 75*235mm/2.95*9.25in Thickness: about 0.1mm Voltage: 3.7V Current: 1.4A Resistance: 2.6O Power: 5.1W Temperature: 45-50?
