SEO Title: Nano Insulation Board TBF-2000 Series | High Temp Thermal Barrier for EV Battery Thermal Runaway Protection
URL Slug: nano-insulation-board-tbf-2000-series
Product Description: TONMAX TBF-2000 Series nano insulation board is silica-based microporous thermal barrier material for lithium battery packs. It restrains thermal runaway propagation and keeps battery performance in cold environment. It maintains low thermal conductivity up to 1200℃, with dimensional shrinkage less than 0.5% at 1000℃. It outperforms aerogel in nail penetration test. Supports PET encapsulation and composite assembly with foam or silicone frames, widely used for prismatic, pouch and energy storage batteries. Keep dry and avoid mechanical damage during storage.

Nano Insulation Board TBF‑2000 Series
Product Overview
TONMAX TBF-2000 Series Nano Insulation Board is a new-generation microporous silica thermal barrier material, including fumed silica based insulation and nano microporous insulation variants. It is specially developed for new energy electric vehicle battery packs. Its core function is to delay the spread of battery thermal runaway, meanwhile providing thermal preservation to improve charge-discharge performance of cells under low-temperature conditions. It can be encapsulated with PET film, or assembled with PU/silicone frames and foam strips. Suitable for prismatic cells, pouch cells, energy storage batteries and other lithium battery thermal isolation applications.
Main Applications
• Thermal runaway barrier and fire insulation for prismatic lithium-ion battery packs of electric passenger vehicles
• Thermal isolation material for soft-pack lithium batteries and power battery modules
• Thermal protection and heat preservation insulation for stationary energy storage battery systems
• Custom composite thermal barrier assemblies combined with foam, silicone frames and wrapping films for battery thermal management

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.
