3240 epoxy phenolic fiberglass cloth laminated sheet
The sheet is made of electrical glass cloth and epoxy resin, which are dried and hot pressed. Its panel is free of bubbles, pits, and wrinkles. It has excellent mechanical properties, outstanding mechanical properties, arc resistance, specifications, and other characteristics. For example, at moderate temperatures, it can effectively exert its mechanical properties; In high temperature environments, its electrical performance can be better utilized. Therefore, due to these characteristics, epoxy boards are very suitable for high insulation structural components in the electrical and electronic fields.
GOP-3 unsaturated polyester glass felt laminated sheet
This sheet is a hard sheet like insulation material made of alkali free fiberglass mat soaked in unsaturated polyester resin paste and added with corresponding additives through hot pressing. The product has good electrical performance, good mechanical performance at medium temperatures, flame retardancy, arc resistance, and resistance to leakage marks. Compared with other laminated materials, GPO-3 has excellent arc resistance (>180s) and resistance to leakage traces (CTI600V); The heat resistance level reaches F level (>160 ℃), and it can work stably in continuously increasing temperature environments, while maintaining good electrical and mechanical properties. It has the characteristics of mechanization, high degree of automation, stable product quality, and low cost; Widely used as insulation structural components in motors and electrical equipment, such as circuit breakers, switchgear, transformers, DC motors, AC contactors, explosion-proof appliances, and other low-voltage electrical appliances.
