Silicone Foam ESF‑7203G‑450
Product Overview
TONMAX ESF‑7203G‑450 is flame‑retardant foamed silicone material made of organic silicone and flame‑retardant agents. Non‑toxic and environmentally‑friendly, it retains stable elasticity and outstanding anti‑compression‑deformation performance under high‑temperature conditions. It is widely used for new‑energy battery‑module thermal management, cabinet bottom support, cabinet sealing, photovoltaic modules, communication equipment and household appliances.
Main Applications
• Bottom supporting and sealing cushion for new‑energy battery modules and battery cabinet assemblies
• Stress‑absorbing gap filler for photovoltaic module assemblies
• Waterproof, shock‑proof and insulating buffer gaskets for telecommunication equipment cabinets
• Multi‑functional damping and sealing components for household electrical appliances
• Corona‑resistant insulating cushion for power electronic assemblies
Core Advantages
✅ Superior fire‑retardant performance and automatic stress‑absorbing capacity to adapt variable stress under dynamic motion environments
✅ Excellent cold‑heat‑shock resistance, waterproof, shock‑proof and outstanding anti‑aging property
✅ Great corona‑resistance, anti‑leakage and reliable electrical‑insulation performance
✅ Low compression permanent deformation under high‑temperature long‑term compression
✅ Multiple optional colors: gray, black, white; custom colors available
✅ Supports die‑cutting processing for custom‑shape gaskets and cushion pads
Storage Note: Store at 23℃ with 65% relative humidity. Avoid direct sunlight and long‑term unpackaged exposure. Shelf‑life: 12 months upon receipt of goods.
