The epoxy insulation board is made of glass fiber cloth and epoxy resin under high heat resistance composite material
Prepreg is pressed into various thicknesses under high temperature and high pressure
Used for Star gear,plastic mould, injection mould, mechanical manufacture, forming machine, drilling machine
Injection machine, motor, pcb,ICT fixture, table grinding pad.
Glass epoxy board has high mechanical and dielectric properties,even in dry and wet environment
cnc epoxy board good heat resistance,can work continuously at 170 degrees
Waterproof,very low water absorption
