Epoxy Fiberglass Insulation Sheet 3240, 0.3-80mm Thickness, 170℃ Heat Resistant

Our Heat-Resistant Epoxy Glass Cloth Fiber Board (3240 Board) is a high-performance laminated insulation material designed for demanding industrial and electrical applications. Manufactured using advanced lamination technology, it combines electrical-grade alkali-free glass fiber cloth with premium epoxy phenolic resin for superior performance.

• Exceptional Heat Resistance: Meets Class B standards (continuous 130°C), maintaining stable mechanical and electrical properties in high temperatures while resisting thermal aging and deformation.
• Superior Insulation Performance: Excellent dielectric strength (rated 600V) with low dielectric loss, providing reliable insulation for electrical components in high-voltage scenarios.
• Robust Mechanical Strength: High tensile strength and impact resistance with dimensional stability (resists warping/cracking). Smooth surface enables precise machining (cutting, drilling) with clean edges.

• Battery Packs: High-reliability insulation layers for lithium-ion and NiMH battery packs, isolating cells from electrical interference and mechanical friction while maintaining stable performance under temperature fluctuations.
• Electrical Field: Key component in switchgear, transformer oil barriers, and high/low-voltage electrical cabinets, ensuring long-term insulation stability and preventing electrical leakage in complex power supply environments.
• Tooling & Molds Industry: Ideal for PCB testing fixtures, ICT fixtures, and mechanical molds, offering high dimensional stability and precise machinability for strict precision requirements.

• Flexible product specifications with thousands of options to meet diverse requirements
• OEM and ODM designs and labels available
• Low minimum order quantities with customizable samples
• Short production cycles and fast delivery times
• Multiple convenient payment methods available
