Our Glass Epoxy Resin Thermal Insulation Sheet
This high quality FR4 grade Epoxy Sheet is commonly used as a electrical insulator because of the excellent performance and strength the sheet can hold.
The 1mm thick sheet has a Tensile strength of up to 40000 Psi, giving you a strong reliable sheet.
Temperature resistance is that of 150°C
The Epoxy Glass is resistant to chemicals and moisture Absorption
Our epoxy resin has a moisture absorption of 0.1% perfect for humid environments since the moisture will not swell the material
With this exceptionally high mechanical strength, electrical strength, Flame and Chemical Resistance, this glass epoxy sheet is excellent against all environments.
Our Inconel 601 Busbar LiFePO4 Cells Connectors
Big Wei Battery uses Inconel 601 (Nickel-Chromium Alloy) as the material of the bus-bars for connecting our LiFePO4 cells for our batteries.Inconel 601 that is highly resistant to oxidation through 1204°C (2200°C).
601 Alloy has outstanding oxidation resistance to high temperature oxidation, the protective oxide coating resists scaling even under severe conditions, the alloy also has good resistance to carburisation and nitridation. Its resistance to sulfur is poor and should not be used in atmosphere where the atmosphere contains sulfur.
