Application Instruction

YESOWOOL® vacuum forming ceramic fiber shapes has become common material for various of energy-saving thermal equipment based on the characteristics of low heat storage and low heat conduction. But in the electric heating furnace, the assembly of ceramic fiber blanket, block and electric heating element is not only expensive but also low reliability.

The integrated electric heating device of "heating and heat insulation" will be produced by adopting vacuum forming technology and selecting high-quality electric heating element to solves the problem of the combination of ceramic fiber and electric heating element

YESOWOOL® vacuum forming ceramic fiber shapes have been made into according to the customer's requirements flat plate , shape arc plate, semicircle, tubular and small furnace, etc., the maximum working temperature even up to 1300 ℃.
