For straight iron, hairdressing hair care products such as hair curler, and pan, hand warmers, hot milk, bean sprouts machine, aromatherapy, wax melting, coffee pot, heat preservation lunch box, refrigerator defrost planar heating and temperature, etc.
New electronic production of this kind of PTC ceramics has the following features:
1 high voltage resistance, up to more than 600 v, to ensure the safety and reliability of hairdressing products long-term work;
2 heating speed, high Curie temperature, the surface temperature up to 310 degree above;
3 surface temperature control precision is high, up to + / - 5 ℃;
4 the rated voltage range is wide, from 1.5 VDC to 380 vac.
5 surface temperature and the dimensions can be adjusted according to customer's request;
6 with aluminum shell mold and insulating paper divides into two classes;
7 service life for more than 10 years;
