3240 Epoxy Resin Board: Electrical Insulator, Mechanical Part & Bakelite Alternative battery raw material

Premium Insulation Material for High Voltage Applications

This product offers flexible customization—available in aqua green, yellow, black, and other colors, with sizes tailored to your specific requirements. It excels in stable performance across conditions: boasting strong mechanical properties at medium temperatures, reliable electrical properties at high temperatures, plus excellent heat and moisture resistance. Its superior mechanical and dielectric performance makes it ideal for high-insulation structural parts in machinery, electrical, and electronic fields, widely applied in motors, electrical equipment, switches, FPC reinforcement boards, PCB-related components, and even humid environments or transformers.

• 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 Li-ion/NiMH packs – isolate cells from electrical interference and friction, maintaining stable performance amid temperature fluctuations.
• Electrical Field: Key in switchgear, transformer oil barriers, and high/low-voltage cabinets – ensures long-term insulation stability and prevents leakage in complex power environments.
• Tooling & Molds: Ideal for PCB/ICT fixtures and mechanical molds – offers high dimensional stability and precise machinability for strict precision needs.

• 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
