Nema G7/ Sigc 202

NEMA G7 is a grade of glass-reinforced melamine laminate material used in electrical and mechanical applications requiring high mechanical strength, dimensional stability, and resistance to moisture and chemicals. It is composed of layers of woven glass fabric impregnated with melamine resin and cured under heat and pressure to form a rigid composite material. NEMA G7 exhibits excellent electrical insulation properties, low moisture absorption, and high mechanical strength, making it suitable for applications such as electrical insulators, terminal boards, gears, and bushings. Its resistance to moisture, chemicals, and heat makes it particularly suitable for use in humid or corrosive environments and in applications where temperature stability is important. NEMA G7 is often chosen for its combination of electrical insulation, mechanical strength, and chemical resistance in various industries, including electrical, aerospace, automotive, and marine.
