Exhaust Insulation Sleeves are typically made from high-temperature resistant materials such as:

1. Fiberglass: Fiberglass is a common material used in Exhaust Insulation Sleeves due to its high-temperature resistance and durability.

2. Ceramic: Ceramic materials are also commonly used in Exhaust Insulation Sleeves due to their excellent thermal insulation properties.

3. Silicone: Silicone is a flexible and heat-resistant material that is often used in Exhaust Insulation Sleeves for its ability to withstand high temperatures and resist degradation over time.

4. Basalt: Basalt is a volcanic rock that is used in some Exhaust Insulation Sleeves due to its excellent thermal insulation properties and resistance to high temperatures.

5. Stainless steel mesh: Stainless steel mesh is sometimes used as a reinforcement layer in Exhaust Insulation Sleeves to provide additional strength and durability.

6. Aluminum fiberglass: aluminum fiberglass can reflect most radiant heat.
