Electric Stainless Steel Heating Element Mica Band Heater for Extruder
Description:
Mica has a unique characteristic in that one can obtain very thin flakes with a consistent thickness. It conducts low amounts of heat, especially perpendicular to its strata. In addition, it is non-flammable, flame-retardant and does not emit fumes
Specification:
Ceramic band heater, mainly used for extrusion,casting and down-stroke machines. The operating temperature can reach up to 600 degree C. The maximum surface loading rate is 8 w/ cm2. Its advantages include fast speed of heating, high rate of heat utilization, excellent energy saving(energy consumption is reduced by 30%), high resistance of high insulation rate. It is one of the most suitable: electric heaters for plastic extrusion and injection machines, plastic hollow and blowing machines and chemical fibre moulding machines.
