Silicone based gap fillers are used to fill gaps from approximately 0.1 – 1 mm in thickness. They function to replace air in the gap and provide a low thermal resistance path for heat flow. Generally these materials should be used under a compression of between 25 – 40% based on the original thickness. T-Global offers three ranges of silicone gap fillers; L37, H48 and TG, these ranges offer solutions for a wide range of engineering applications.
