High-temperature silicone HTS 300
HTS 300 is a pasty, non-flowing, one-component silicone rubber specifically developed for industrial applications at high temperatures. With resistance up to 230 °C (short-term up to 350 °C), it is ideal for sealing and bonding in areas such as chimney construction, industrial furnaces, and engine repair.
