Thermally conductive electrical

insulators (Contents)

GT 907 is an RTV polyaddition silicone elastomer, fluid and curing at room Thermally conductive electrical insulators are used at the component/radiator interface.
temperature with no solvent requirements. When vulcanised it has 5
good thermal conductivity and flame-resistance (UL 94 V0). They have numerous advantages over conditional grease-based products.

They eliminate the problems associated with silicone greases.These elastomers are glass-fiber reinforced,
they are supple and they compensate for surface imperfections in the component and radiator.
