Thermally conductive sheet for exchanger elements
Priced against your drawing, quantity and material grade. Send the specification and we will come back with a firm rate.
Thermally conductive sheet for exchanger elements and power assemblies needing sheet-form conversion.
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.

Supplied as pre-cut package shapes or as sheet stock for your own tooling. The reinforced construction is what lets these run under bolted clamping loads without losing isolation.
This grade is specified most often in the assemblies below. Each page covers the thermal and dielectric requirements of that application in detail.
Specification tables and definitions for this material family, from the Perfect Insulations technical team.
The EXCH-EL has a thermal conductivity of 2.0 W/m·K and a dielectric strength of 4.0 kV/mm, so it conducts heat away from the device while keeping it electrically isolated from the heatsink or chassis.
Standard thicknesses are 0.5mm, 1mm, 2mm. Other thicknesses can be produced to order against your drawing.
Stock sizes are Sheet, Custom die-cut. 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.
This grade is quoted per enquiry rather than list-priced, because the rate depends on the cut part and the quantity. Send your drawing and annual volume for a firm price. All prices are exclusive of 18% GST.
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.
