DF204 Epoxy Glass Cloth Laminate

Product features: DF204 epoxy glass cloth laminate is made by impregnating alkali-free glass cloth treated with silane coupling agent with epoxy resin and hot pressing. It is an F-class epoxy glass cloth laminate produced according to the requirements of the IEC60893-3-2 "Specification for Industrial Rigid Laminates of Thermosetting Resins for Electrical Use". It has the characteristics of high mechanical strength at medium temperature or hot state, good electrical performance at high humidity, high breakdown voltage in parallel layer direction, flame retardant, etc. Application areas: DF204 epoxy glass cloth laminate is suitable for Class F motors, electrical equipment as insulation structural parts and other uses with insulation and flame retardant requirements. Thickness range: 0.2mm--100mm Main dimensions: 1500mm * 3000mm, 1220mm * 3000mm, 1020mm * 3000mm, 1020mm * 2440mm, 1220mm * 2440mm, 1500mm * 2440mm, 1000mm * 2000mm, 1200mm * 2000mm and other sizes based on the agreement between the supply and demand sides.
