Carbon Fiber Electric Quartz Heating Elements For Heaters, Far Infrared Quartz Heating Tube Quartz Glass Tube Heater OD10 12mmCarbon fiber electric heating tube Model: YH 001 Pipe diameter: 10mm 12 mm Material: Japanese Mitsubishi and Russian raw silk Carbon fiber heating element is a pure black body material, so it has the characteristics of rapid temperature rise, small thermal lag, uniform heat generation, long heat radiation distance, and fast heat exchange speed. In the working process, the luminous flux is much smaller than the electric heating tube of the metal
