Elastic thermo insulating Fiberglass-Metal tape resistant to high temperatures. Made of Fibreglass fabric combined with Aluminum layer which makes it more flexible. Its elastic capacities can be easily applied also to the exhaust elbows. It usually takes 2/3 layers to be sufficient for most diesel exhaust systems. Maximum operating temperature: 600°C. A protective outer layer of self-amalgamating elastomer tape resistant to high temperatures can be added to create a homogeneous surface.
