DF205 modified melamine glass cloth laminate

Product features: DF205 modified melamine glass cloth laminate is made by impregnating alkali-free glass cloth treated with silane coupling agent with modified melamine resin and hot pressing. It has high mechanical and electrical properties and excellent arc resistance. Application areas: DF205 modified melamine glass cloth laminate is suitable for B- class motors, electrical equipment as insulation structural parts and other insulation fields with special requirements for arc resistance. 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.
