Gap pad vo ultra soft thermally conductive conformable gap filling material bergquist gpvous 0125 00 0404 gap pad vo ultra soft is an electrically isolating thermally conductive interface material from bergquist because of its low hardness and low modulus design it has an ultra conformable performance making it ideal for applications where minimal pressure on components is required and where a very uneven interface gap exists air gaps and voids being filled in minimising interfacial resi
