AES Fiber Class. Expandable fiber grade. Superwool 351-E expandable paper is an intumescent material produced from a unique blend of Superwool bulk fibers, special additives, and organic binders. At maximum expansion which occurs at approximately 1200°F (649°C), the paper expands up to 400% of its thickness. This results in the 351-E paper being an excellent candidate for high temperature gaskets and seals, and fire protection applications. During heat up and expansion, there will be some additional outgassing of the intumescent additives. Applications: - All-purpose high temperature gasketing and sealing
- Fire protection
- Fire doors
- Expansion joint insulation
- Fireplace catalytic converter gasketing
- Aluminum filter bowl gasketing
