Description
Gongtao can supply and custom made the steatite ceramic products according to customer's drawings, samples and performance requirement.
Property:
1. High resistivity
2. Moderate strength
3. Excellent electrical properties
4. Poor heat conductivity (thermal insulator).
5. Good resistance to thermal shock.
6. Low coefficient of thermal expansion.
7. Good mechanical stability.
Applications:
Heating element holders
Stand off insulators
Interlocking insulating beads
Splitbush insulators
Lamp bases and caps
Regulator parts
These beads are for protecting power lead wires with different size.
Material: White steatite ceramic, yellow steatite, alumina.
