DF350A modified diphenyl ether glass cloth laminate

Product features: DF350A modified diphenyl ether glass cloth laminate is made of KH560 treated alkali-free glass cloth impregnated with modified diphenyl ether resin and hot pressed. Good heat resistance, high temperature impact strength, tensile strength and compression strength and other mechanical properties, good electrical properties, good flame retardancy. Application areas: It is suitable for use as insulating structural parts in H-class motors and electrical equipment, or in motors and electrical appliances with high mechanical strength requirements under thermal stress. 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.
