High temperature resistance Cordierite heating plate for Heating Wire use
Unmatched Thermal Resilience: The Cordierite Advantage
The core strength lies in cordierite's exceptionally low coefficient of thermal expansion (CTE: 1.0 - 2.5 x 10⁻⁶ /°C, 25-1000°C). Unlike metals or standard ceramics that warp or crack under rapid temperature cycling, the Ultra-Thermal™ platform exhibits near-zero dimensional change. This intrinsic property grants it superior thermal shock resistance, effortlessly surviving repeated thermal cycling from ambient temperatures to continuous operating temperatures exceeding 1250°C (2282°F), with peak tolerance reaching 1400°C (2552°F). This makes it ideal for applications involving rapid startup/shutdown cycles or exposure to intense localized heat from high-resistance heating wires.
Optimized for Heating Wire Performance & Protection
-
Stable, Non-Warping Surface: Provides a perfectly flat, rigid base that prevents heating wire sagging, distortion, or short-circuiting even at maximum operating temperatures, ensuring consistent heat distribution and electrical isolation.
-
Exceptional Electrical Insulation: Maintains high dielectric strength and volume resistivity at extreme temperatures, critically preventing current leakage or arcing to surrounding components, enhancing operational safety.
-
Chemical Inertness: Resists oxidation and corrosion from common furnace atmospheres, fluxes, or accidental spills (molten salts, certain metals), protecting both the platform and the heating wire from degradation. Resistant to reducing and oxidizing environments.
-
Mechanical Durability: Offers excellent creep resistance and structural stability under prolonged thermal load, supporting heavy heating wire coils or assemblies without deformation.
Key Applications Driving Innovation
