3R2333

Ceramic paper

The 3R2333 expandable paper is produced from a unique blend of high-purity ceramic fibers, special additives, and organic binders. At maximum expansion of approximately 1200°F, the paper expands up to 400% of its thickness. These results demonstrate that this product is excellent for fabricating seals. It is also recommended for its excellent flexibility, outstanding handling characteristics, and high-insulating value. However, during heat up and expansion, there will be some additional out-gassing of the expandable additives.
