Ceramicization Technology: From Polymer to Ceramic Under Heat
When exposed to temperatures exceeding 500°C, the silicone matrix undergoes controlled ceramicization, forming a rigid, porous ceramic structure while retaining the foam’s original shape. Key advancements include:
Self-supporting ceramization: The glass fiber reinforcement prevents collapse during phase transition, maintaining >80% volume integrity (per ASTM D3574).
Endothermic reaction: Absorbs 1,200–1,500 J/g during decomposition, delaying heat transfer (tested per ISO 5660-1).
Low thermal conductivity (0.12 W/m·K): The ceramicized layer acts as an insulating barrier, reducing heat flux to protected components.
Temperature range:
Short-term: Withstands 1,200°C (e.g., jet engine firewall seals).
Continuous use: Stable at –60°C to +350°C (industrial furnace gaskets).
Compression recovery (30–50%): Resilient under cyclic thermal expansion (tested per ASTM F38).
Tensile strength (2.0 MPa): Glass fiber reinforcement resists cracking during vibration.
UL 94 V-0 rated: Zero flaming droplets, critical for aviation and rail.
ASTM E119 fireproofing: Achieves 2-hour fire barrier certification for construction.
Energy: Seals for lithium-ion battery packs (prevents thermal runaway propagation).
Aerospace: Firewall gaskets in engines and auxiliary power units (APUs).
Industrial: Expansion joints in steel mills and chemical processing pipelines.
Non-toxic smoke: Meets FAA smoke density requirements (<5 Ds max per ASTM E662).
Zero halogen: Complies with EN 45545-2 for rail transportation.
Service life >15 years: Resists UV, ozone, and thermal aging (per ASTM D573).
Precision die-cutting: Tolerances ±0.2 mm for complex geometries (e.g., turbine housing seals).
Hybrid designs: Combine with conductive fillers for EMI shielding + fireproofing.
Rapid prototyping: 3D-knife cutting for R&D validation within 72 hours.
