Properties and Application It is a kind of rigid insulating material which is made of non-alkali glass cloth impregnated with epoxy resin, by processing of winding under heat and pressure in molds, and then baked and solidified. It offers good electrical, mechanical and machining properties. It is suitable for electrical devices as structural insulating parts, especially in humid conditions. |
