Our flagship product—Heat-Resistant Epoxy Glass Cloth Fiber Board (also called 3240 Board, Epoxy Fiberglass Sheet, or Insulating Glass Fiber Material Board)—is a high-performance laminated insulation material for tough industrial and electrical uses. Made via advanced lamination, it uses top-grade electrical alkali-free glass fiber cloth as the base and premium epoxy phenolic resin as the binder, formed into a uniform, dense, durable structure through soaking, baking, and hot-pressing.
Key Features
High Heat Resistance: Meets Class B heat resistance standards (continuous operating temperature up to 130°C), maintaining stable mechanical and electrical properties even in high-temperature environments, with excellent resistance to thermal aging and deformation.
Superior Insulation Performance: Offers excellent dielectric strength (rated voltage up to 600V) and low dielectric loss, providing reliable insulation protection for electrical components and preventing leakage and short circuits in high-voltage scenarios.
Strong Mechanical Strength: Features high tensile strength, impact resistance, and dimensional stability—resisting warping or cracking under external pressure.
Easy Precision Machining: With a smooth surface, it enables precise processes like cutting and drilling, resulting in neat edges without burrs, suitable for fine assembly needs.
Customization Adaptability: Supports customized thickness and size per customer requirements, flexibly matching diverse installation and usage needs in industrial and electrical scenarios.
