Product Overview:

 

1. Characteristics

It’s rapid temperature rising, with small bulk, with high power in unit area, with low oxidation, longer aging than wire heaters. It’s with temperature coefficient of + 2000~3000×10-6/. The steady power is changed slightly with temperature changing. The steady power is lower than inrush power. Temperature control circuit is needed for controlling the temperature.

2. Application

The insulating materials can be consisted of ceramic, glass, mica and so on. It can be used in hair straightener, hair crimper, and other appliances.

3. Dimension  Unitmm

3.1  Heating plate with single insulator .

 

 

3.2  Heating plate with insulator on both two sides.
