Diphenyl ether is made of alkali free glass fiber cloth immersed with phenol modified diphenyl ether resin by baked and hot press to form into laminate products which has good mechanical and dielectric property is suitable for electrical machinery, electric equipment for insulation structure parts.
surface smooth without bubbles, pit and wrinkle. It allows a little spots. The edge need cut neatly without crack and layering.
