Industrial Electrothermal Cordierite Ceramic Transformer Bobbin Insulator
Cordierite Ceramic Bobbin(Head and Bottom) is mainly used as Ceramic Bobbin Heater.
Cordierite ceramics are extensively used in important industrial applications such as micro electronics, refractory products, heat exchanger for gas turbines, thermal shock-resistant table ware, catalyst supports, and porous ceramics. Low-expansion cordierite is suitable for being applied at high temperature circumstance where a good thermal shock resistance is required.
