Silicone Foam ESF‑7203G‑900
Product Overview
TONMAX ESF‑7203G‑900 is ultra‑high‑stress organic silicone foam material, featuring excellent electrical insulation performance and outstanding resistance to compression permanent deformation. Compared with traditional carbon‑based foam materials, it delivers remarkable high‑low‑temperature resistance ranging from ‑55℃ to 200℃, together with superior anti‑aging and weather‑resistant properties. It is an ideal material for heavy‑duty shock absorption, buffering, structural support, sound insulation, mechanical protection and electrical‑insulation applications.
Main Applications
• Ultra‑high‑load gap buffering and structural support for new‑energy battery modules and battery cabinet assemblies
• Heavy‑stress shock‑absorbing and sound‑insulating gaskets for large‑capacity energy‑storage equipment housings
• High‑compression protective and insulating cushion components for photovoltaic module assemblies
• Heavy‑duty buffering and supporting parts for communication‑equipment cabinets
• High‑load insulating cushion for industrial electronic assemblies under extreme compression conditions
Core Advantages
✅ Excellent electrical‑insulation performance with high dielectric strength
✅ Outstanding anti‑compression‑deformation and anti‑creep performance under long‑term heavy compression
✅ Wide operating temperature‑55℃ ~ 200℃, passes‑55℃ low‑temperature bending test
✅ Ultra‑high compressive bearing capacity, designed for heavy‑load supporting scenarios
✅ Low water‑absorption rate, good anti‑aging and weather‑resistant performance
✅ RoHS, REACH, ELV compliant for global automotive and battery supply‑chain
✅ Supports die‑cutting 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.
5、Exclusions from After-sales Warranty
① Damage caused by expired shelf life or improper storage conditions;
② Quality complaints raised after the customer cuts, processes or modifies the products;
③ Wrong product selection or operation beyond permissible working conditions;
④ Man-made damage, tearing by external force, or corrosion by chemicals;
⑤ Damage caused by force majeure such as fire, flood and other natural disasters.
