High temperature G11 epoxy glass sheet
Indicative per sheet, excludes 18% GST; confirm on RFQ.
G11 high temperature epoxy glass laminate sheet for electrical insulation parts exposed to elevated heat and mechanical load.
Fibreglass-reinforced silicone pads carry a woven glass carrier through the middle of the sheet. That carrier resists cut-through when a transistor is bolted down hard against a heatsink edge, so the pad keeps its dielectric barrier under mounting pressure where an unreinforced pad would puncture.

The FRP-G11 is rated at 22 kV/mm.
Standard thicknesses are 1.5mm, 3mm. Other thicknesses can be produced to order against your drawing.
Stock sizes are 300x300mm, 300x400mm, 1000x1000mm, Custom size. We also supply it die-cut to your own outline, so the sheet size need not constrain the part.
Yes. Perfect Insulations is a converter as well as a supplier — steel-rule die cutting, punching and folding, and slit rolls are all done in-house at our Bengaluru works. Send a drawing or a sample with the annual quantity and we will quote the tooling and the piece rate.
Indicative rates run from ₹330 to ₹4,600 per piece depending on size and thickness, and fall as the quantity rises. Prices exclude 18% GST. The firm rate comes from a quote against your drawing and quantity.
Yes. We despatch nationwide from Bengaluru by courier, with freight charged on parcel weight. GST is billed as CGST+SGST within Karnataka and IGST for every other state.
Perfect Insulations has manufactured thermal and electrical insulation in Bengaluru since 1995, and works to ISO 9001:2015. We supply this grade as sheet stock or die-cut to your drawing, in OEM quantities, across India. See how die-cut parts are made and quoted.
