Ceramifiable Silicone Foam VT‑7203TC‑350
Product Overview
TONMAX VT‑7203TC‑350 ceramifiable silicone foam is medium‑high‑stress ceramic‑forming silicone foam material with outstanding resistance to compression permanent deformation. When exposed to high‑temperature conditions, the foam will convert and form a dense ceramic fire‑retardant barrier layer. Compared with traditional carbon‑based foam materials, it delivers excellent high‑low‑temperature performance ranging from ‑55℃ to 200℃ and UL94 V‑0 high‑flame‑retardant grade. It also possesses superior anti‑aging and weather‑resistant properties. It is an ideal material for shock absorption, buffering, structural support, sound insulation, mechanical protection, electrical insulation and fire‑safety applications.
Main Applications
• Cell‑to‑cell buffering, gap filling and fire‑blocking cushion for new‑energy power battery modules
• Shock‑absorbing and fire‑resistant sealing components for EV battery pack housings
• Insulation & buffer parts for energy‑storage battery cabinet thermal management
• Multi‑functional damping, supporting and fire‑safety gaskets for power electronic assemblies
• Sound‑insulation and protective cushioning for high‑temperature industrial equipment
Core Advantages
✅ Excellent flame retardancy and fire‑blocking performance; forms ceramic barrier layer under high‑temperature to restrain fire spread
✅ Outstanding anti‑compression‑deformation and anti‑creep performance, maintains stable cushioning under long‑term compression
✅ Wide operating temperature window of ‑55℃ ~ 200℃; no cracking under 800℃ short‑time high‑temperature exposure
✅ Reliable electrical insulation performance, low‑water‑absorption for stable damp‑environment performance
✅ RoHS, REACH, ELV compliant, eco‑friendly for automotive and battery global supply‑chain
✅ Good processing performance, supports die‑cutting for custom‑shaped gaskets and pads
Storage Note: Store in cool and dry environment below 27℃. Shelf‑life: 10 years for unopened products.
