Cordierite Ceramic bobbin for water heater
Ceramic bobbin heater is made of porous cordierite ceramic heating element with wire.
Application: Heating element holders,Stand off Insulators,Interlocking Insulating Beads&Pins,Lamp bases and caps,Thermostat part
Why choose Cordierite materials
A. outstanding thermal shock resistance
B. high degree of electrical insulation strength
C. corrrosion resistance
D. high heat resistance(C530 up to 1300℃,specialities up to 1600℃)
E. comparatively lower production costs
