Silicone Foam HES‑7203G‑550
Product Overview
TONMAX HES‑7203G‑550 is high‑stress organic silicone foam material, featuring low density and excellent resistance to compression permanent deformation. Compared with traditional carbon‑based foam materials, it delivers excellent high‑low‑temperature resistance from ‑55℃ to 200℃ and UL94 V‑0 high flame‑retardant grade. It also has outstanding anti‑aging and weather‑resistant performance. It is an ideal material for shock absorption, buffering, structural support, sound insulation, mechanical protection, electrical insulation and fire‑safety applications.
Main Applications
• High‑stress gap cushion and structural support for new‑energy battery modules and battery cabinet assemblies
• Shock‑absorbing and sound‑insulating gaskets for large‑scale energy‑storage equipment housings
• Protective and insulating buffer components for photovoltaic module assemblies
• Buffering and sealing parts for communication‑equipment cabinets
• Fire‑retardant insulating cushion for high‑load industrial electronic assemblies
Core Advantages
✅ Excellent flame‑retardant and fire‑safety performance, UL94 V‑0 certification
✅ Outstanding anti‑compression‑deformation and anti‑creep performance under long‑time compression
✅ Passes‑55℃ low‑temperature bending test, reliable performance under wide temperature range
✅ High tensile strength and high elongation for complex assembly deformation
✅ High dielectric strength, stable electrical‑insulation performance
✅ Multiple optional colors: gray, black, white with custom‑color available; RoHS, REACH, ELV compliant
✅ Supports die‑cutting for custom‑shape gaskets and cushion pads
Storage Note: Store inside carton at 23℃ and 65% relative humidity. Avoid direct sunlight and long‑term unpackaged exposure. 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.
