I. Introduction
 
Hony® GPO-3 sheet, also known as UPGM203, is a standard electrical insulating material with excellent arc resistance and heat resistance. The product is a hard plate-shaped insulating material which is obtained by hot-pressing an unsaturated polyester resin paste by an alkali-free glass fiber felt.

II. Features
♦ Compressive strength, flexural strength and tensile strength are relatively high. Under different environments (temperature, medium, humidity), the material is subjected to various applied loads (stretching, compression, bending, torsion, impact, alternating stress, etc.) The mechanical characteristics exhibited by the system are very good and can withstand a certain degree of impact.
♦ Casting performance, cutting performance, welding performance, stamping performance, heat treatment performance is better, and metal-made processing equipment can be used to easily process molded products.
♦ The size is very fixed, the allowable variation in the actual parameter values ​​of the thickness is very small, and the thickness tolerance can be met without further processing.
♦ In the case of high humidity, it is very stable in electrical performance, which can prevent the surface of the solid insulating material from gradually forming a conductive path under the combined action of electric field and electrolyte.
♦ Effective resistance to deterioration caused by high voltage arcing (greater than 180 seconds).
♦ There is a very high maximum operating temperature: the temperature will be more than 240 °C to deform. The heat resistance rating is usually "F" or "H".
♦ The material has the characteristics of slowing, terminating or preventing flaming combustion: it meets the UL94 V-0 standard in the United States; it does not contain halogen elements, and the system emits little smoke if it is ignited.
♦ Good thermal mechanical strength, good mechanical and electrical performance in a continuously elevated temperature environment
♦ The performance of anti-leakage traces is very good (CTI>600V)
 
III. Field of application
 
♦ Application of GPO-3 in molded case circuit breaker: phase partition plate, arc chamber arc plate, etc.
♦ GPO-3 application in motor motor: motor armature parts, movable cover, wedge stator, fixed gasket, thin gasket, carbon brush holder, etc.
♦ Other applications: suitable for various switchgear separators, linings, arc-extinguishing hoods, arc extinguishing cylinders, arc extinguishing plates, arc shields, terminal blocks, contact supports; structural support for switches and transformers, busbars Splint, busbar slot insulation; motor armature components, signal board; electric furnace, electric furnace insulation, etc.
