Ceramic paper

Produced from a mix of high purity fibers and organic binders, this paper is noted for its low thermal conductivity and good thermal insulation. It also is known for its excellent tensile strength and outstanding handling characteristics.


The 3R2970 is an excellent backup for the refractory products and is an interesting material for fabricating expansion joints. Also, it is easily die cut to make high temperature seals in complex shapes.
