  • Description
1. Excellent Electrical Insulation Performance
It maintains stable dielectric strength under room and moderate high temperature conditions, effectively isolating electric current, preventing short circuit and electric leakage. It works reliably for high-voltage components and sensor assemblies.
2. Outstanding High Temperature Stability
Continuous operating temperature reaches 1300–1450°C, with melting point up to 1853°C. It suffers minimal high-temperature creep and maintains dimensional stability under long-term heat load.
3. Superior Thermal Shock Resistance
Thanks to low coefficient of thermal expansion, mullite ceramic withstands frequent rapid heating and cooling cycles. It is less likely to crack under thermal shock compared with ordinary alumina ceramics.
4. Strong Chemical Inertness
Resistant to oxidation, acid and alkali corrosion. It does not react with most molten metals, gas atmospheres, avoiding contamination to surrounding components.
5. Balanced Mechanical Properties & Cost Advantage
It provides decent flexural and compressive strength. Compared with high-purity alumina ceramic, mullite insulator delivers comparable insulation performance at a more competitive cost.
6. Low Thermal Conductivity
It offers dual functions: electrical insulation plus heat insulation, reducing heat transfer between assemblies.

shenxing ceramic 1-8 holes heating resistance insulator steatite ceramic stick for band heater

A ceramic stick for a band heater is a key component in ceramic band heaters, which are widely used in plastic processing machinery and other equipment. It is usually made of high - frequency ceramic materials and has the characteristics of fast heat transfer, high hardness, and resistance to high temperatures and aging. The ceramic stick is mainly used to thread the heating wire. The heating wire, usually made of high - temperature - resistant nickel - chromium alloy, is wound into a spring shape and then passed through the ceramic stick. This structure enables the ceramic band heater to have a higher power than ordinary heaters and can quickly generate and transfer heat during operation.
