Silicone Foam VT‑7203G‑220
Product Overview
TONMAX VT‑7203G‑220 is medium‑stress organic silicone foam material featuring low density and outstanding resistance to compression permanent deformation. Compared with traditional carbon‑based foam materials, it exhibits excellent high‑low‑temperature resistance ranging from ‑55℃ to 200℃ and UL94 V‑0 high‑flame‑retardant grade. It also delivers superior anti‑aging and weather‑resistant performance. It is an ideal material for waterproof sealing, shock absorption, buffering, structural support, electrical‑insulation protection and fire‑safety applications.
Main Applications
• Waterproof‑sealing and gap‑buffering cushion for new‑energy battery modules and cabinet assemblies
• Shock‑absorbing and insulating gasket for energy‑storage system equipment housings
• Low‑stress sealing and thermal‑insulation parts for photovoltaic module assemblies
• Buffering and sealing components for communication‑equipment cabinets
• Multi‑functional fire‑resistant sealing & damping foam for household and industrial electronics
Core Advantages
✅ Excellent flame‑retardant and fire‑safety performance, meets UL94 V‑0 standard
✅ Outstanding anti‑compression‑deformation and anti‑creep properties under long‑time compression
✅ Wide operating temperature‑55℃ ~ 200℃, passes‑55℃ low‑temperature bending test
✅ Low density and low thermal conductivity for lightweight thermal‑insulation design
✅ Reliable dielectric strength and good electrical‑insulation performance
✅ RoHS & REACH compliant, eco‑friendly for automotive and battery supply‑chain
✅ Supports die‑cutting processing for custom‑shape gaskets and cushion pads
Storage Note: Store in cool and dry environment below 27℃. Shelf‑life: 10 years for unopened products.

1、Inspection upon Receipt
Within 3 working days after receipt of goods, the customer shall unpack and inspect the shipment, and verify the model, specification, quantity and appearance of products. If any abnormality such as damage, wrong delivery or model mismatch is found, please contact us with photos or videos as evidence. Failure to notify us within the time limit shall be deemed acceptance of the product in terms of appearance and quantity.
2、Product Application Scope
All technical data of our products are typical values obtained from standard laboratory tests, for reference only in product selection. Customers shall conduct sampling tests and reliability verification in advance according to their own working conditions, service environment and assembly requirements, and confirm compatibility before mass use. Product failure caused by skipping pre-sample verification or operating beyond the rated temperature, pressure and other permissible conditions is not covered by warranty.
3、Storage & Shelf Life
Products shall be hermetically stored in a cool, dry and dark place. Keep away from high temperature, moisture, oil contamination and prolonged UV exposure. Use the products within the shelf life marked on the label. Deterioration or premature aging resulting from improper storage by the customer is excluded from after-sales service.
4、Handling of Quality Claims
If the non-conformity is confirmed by both parties to be an inherent material quality defect, we will prioritize replacement, supplementary delivery, or negotiate a refund. We shall NOT be liable for any indirect losses including secondary processing, finished product assembly, construction work, production shutdown losses, etc.
