Temperature uniformity is good in whole surface compared to line heating or partial heating method..
Because of the heating rate is very fast after applying electric power, it is very useful compared with the conventional preheating method.
It is pollution-free, environment-friendly heating material that it does not generating dust, harmful gases, germs, noise, and vibration.
90% or more far-infrared radiation is generated, that make smooth metabolism and comfortable sleep.
