GPO-3 Insulation Board Electrical Insulation: All electrically insulating laminated products are inherently high quality insulators. Here, in accordance with the characteristics of the grades, their optimized special properties are utilized for a wide range of electrical applications in the field of engineering and technology.
GPO-3 Insulation Board Flame Retardant: Grades 1580 and UTR are UL-rated V-0. Grade UTR is halogen free and the system emits very little smoke and toxic fumes in the event of a fire.
Mechanical Strength: High strength glass fiber reinforced polyester laminates will not shatter. Rigid laminates provide structural support due to their isolation properties. Flexible laminates can be utilized in applications with a minimum bending diameter of 19mm.
Thermal Performance: The laminates provide excellent protective properties and spatial stability during warming. These laminates are UL temperature rated in the 120-210°C electrical and 130-210°C mechanical ranges.
Easy to Form: These materials can be easily formed using standard metal handling equipment. They can be stamped, drilled, machined, sheared and sanded.
