TG4040LC is an ultra-soft, silicone based thermal interface material which has one face naturally tacky and one face dry. TG4040LC has a low thermal impedance, conforms readily to surfaces due to its low hardness and provides a high dielectric breakdown voltage. TG4040LC can be provided in various thicknesses and formats, such as custom die cuts, standard sheets or log rolls depending on the end application.
