Cell‑to‑Cell High‑Stress Cushion Silicone Foam ESF‑7203G‑750P
Product Overview
TONMAX ESF‑7203G‑750P cell‑to‑cell high‑stress cushion silicone foam is high‑hardness silicone foam material. Compared with conventional carbon‑based foam materials, it delivers outstanding high‑low‑temperature resistance, high‑level flame retardancy and extremely low smoke density. It also features remarkable aging‑resistance and weather‑resistance. It serves as ideal material for high‑performance sealing, shock‑absorbing, supporting, sound‑insulation, mechanical protection, electrical insulation and fire‑safety applications.
Main Applications
• High‑stress gap cushion and support between lithium‑ion cells inside power battery modules
• Shock‑absorbing, sealing and insulating components for new‑energy vehicle battery packs
• Sound‑insulation & buffer parts for energy‑storage battery cabinet assemblies
• High‑temperature resistant sealing and vibration‑damping gaskets for industrial equipment
• Protective insulating cushion for high‑stress electronic assemblies
Core Advantages
✅ Fine and uniform cell structure, low density to satisfy lightweight design requirements
✅ Excellent flame‑retardant performance, meets UL94 V‑0 standard with low smoke emission
✅ High compressive‑stress performance, low compression set under high‑temperature aging
✅ Wide operating temperature range ‑55℃ ~ 200℃, great weather and aging resistance
✅ Reliable electrical insulation performance with low water‑absorption rate
✅ Compliant with RoHS, REACH, ELV environmental standards for automotive & battery supply‑chain
Storage Note: Store in cool and dry warehouse, avoid direct sunlight. Shelf‑life: 12 months from production date for roll‑form products.
