Pre‑Oxidized Fiber Aerogel Felt VT‑6630N
Product Overview
TONMAX VT‑6630N black pre‑oxidized fiber aerogel felt is high‑performance thermal insulation felt composited of nano‑aerogel and organic fiber materials by special process. Aerogel is well‑known solid material with ultra‑low thermal conductivity. This composite felt delivers low thermal conductivity, waterproof, fire‑retardant and eco‑friendly properties. Even at ultra‑thin thickness, it achieves equivalent insulation performance of traditional thicker materials, reducing heat loss and improving space utilization rate. It features good flexibility and high tensile strength. Besides thermal insulation for batteries, it also performs sound‑absorbing, noise‑reduction and vibration‑buffering functions to protect battery systems. It meets RoHS and REACH requirements, ideal for battery thermal‑insulation and buffering applications.
Main Applications
• Thermal insulation & fire barrier for new‑energy lithium‑ion battery modules
• Vibration buffering and shock protection inside battery packs
• Sound absorption and noise reduction for battery assemblies
• High‑efficiency thermal insulation for compact‑space battery systems
Core Advantages
✅ Ultra‑thin thickness achieves same insulation effect as traditional thick materials, less heat loss, higher space utilization ✅ Good flexibility and high tensile strength, easy for cutting and die‑cutting processing
✅ Multi‑functional: heat preservation, sound absorption, noise reduction and vibration buffering to protect batteries
✅ Ultra‑low thermal conductivity under different temperature conditions
✅ UL94 V‑0 flame retardant grade, high hydrophobic rate ≥98%
✅ Compliant with RoHS & REACH environmental standards
Storage Note: Store in cool, dry and well‑ventilated warehouse. Do not open original package before use to reduce dust generation. Dispose cutting waste timely. Storage temperature ≤40℃, humidity ≤75%RH.

To help you fully understand the acceptance procedure, application requirements, storage specifications and after-sales liabilities, please read the following terms carefully before purchasing and using our 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.
