Well suited for mechanical and electrical applications, excellent mechanical and electrical strength at room temperatures,excellent heat resistance, good performance against arc and tracking, toxic-free,flame resistant, low smoke, meet EN45545 standard
Application:
l Electrical Applications:
They are commonly used in the electrical and electronics industries for making circuit breaker housings, switchgear panels, and other components where electrical insulation is critical.
l Transportation:
In the automotive and rail industries, UPGM sheets are used for components that require both structural integrity and insulation properties, such as under-the-hood components and interior panels.
l Industrial Equipment:
These sheets are used in the manufacturing of parts for machinery and equipment that require high strength, insulation, and resistance to environmental factors.
l Construction:
UPGM sheets find applications in construction for fire-resistant panels and other structural components that benefit from their thermal and chemical resistance.
