Product Introduction

Product description

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.
