Technical laminates - sheets
GLASS SILICONE SHEET - Hgw 2572
Laminated material in sheets, made from nonalkaline glass fabric as a fortifier material and silicon resin. The material has high thermal resistance (class H) and good dielectric properties. The sheet colour is from wax white to wax yellow. The material is suitable for electrical devices with heat class H and for the places where is required high thermal resistance and small decline of electrical and mechanical properties under the working temperatures.
Available dimensions: 1025x1245 mm, 1050x2800 mm
Available thickness: 0,3 mm – 50 mm
