Steatite Ceramic usuallly called C221 High frequancy ceramic, which is a low cost material with high electrical resistance at high temperatures, good mechanical strength and a very low dielectric loss factor. Such properties make it ideal for high frequency, low loss, and high voltage insulation. Steatite has been used for many years in large-scale industrial systems, household electronic appliances, aerospace and automotive applications, and specialized eletro-technical instruments such as cathode-ray tubes.
Applications :
(1) Ceramic Band Heater Insulator;
(2) Heating element holders;
(3) Stand off Insulators;
(4) Interlocking Insulating Beads;
(5) Split bush insulators;
(6) Lamp bases and caps;
(7) Regulator parts
Shengda Ceramic provide all kinds of steatite ceramic tubes. Also the rings, rods, tubes, plates, inserts, bushing, sleeves, blocks, plunger and so on. Any dimension requirement, please contact us.
Steatite Ceramic
Steatite ceramic is made of natural mineral talc as the main raw material and enstatite as the main crystal phase. Good dielectric property and low price. The disadvantages are large coefficient of thermal expansion, poor thermal stability and low strength compared with high alumina ceramics.
Advantage
1 Strong acid resistance
2 Strong insulation
3 Strong adsorption
4 High thermal insulation performance
5 Good chemical stability
6 High compressive strength
Features
1) A variety of specifications available.
2) Satisfy various technical request
3) Lower medium spoilage
4) Good insulation performance and high temperature resistance
5) High strength
6) Used in all electric products, electric heating products and wear resistant machinery parts.
7) OEM, ODM and OBM are welcomed
