FR4 Epoxy Resin Sheet Insulation Board for High Voltage Epoxy Fiberglass Sheet lithium-ion Battery Pack manufacturer

As a professional manufacturer of high-performance insulation materials, we take pride in our FR4 Epoxy Resin Sheet. This Epoxy Resin Sheet is specifically engineered for high-voltage environments and lithium-ion battery packs. Its core advantage lies in its outstanding electrical insulation properties, including high dielectric strength and superior arc resistance, ensuring critical safety in dense battery modules. Additionally, this Epoxy Resin Sheet offers excellent mechanical strength, low moisture absorption, and flame-retardant performance (UL94 V-0), making it the ideal structural and insulating component for high-voltage epoxy fiberglass applications in modern energy storage systems.

How to avoid micro cracks inside the epoxy resin board during processing?

1. Choose a crack resistant grade Optimization of glass fiber content: Priority should be given to using epoxy resin boards reinforced with medium alkali glass fibers (such as EC10-13) or hybrid fibers (glass fiber+aramid), which have a 20% -30% higher elongation at break than high alkali fiber boar
