CERMEX PR2300 RCF PAPER from Mid-Mountain Materials is a high-purity alumina-silica insulating material. The lightweight material exhibits low thermal conductivity and high strength properties. The highly uniform material has low shot content, making it suitable for application as seals and gaskets. It has also found use in other thermal barrier applications.
CERMEX PR2300-U RCF PAPER is another refractory ceramic fiber paper from Mid-Mountain Materials. This is also a lightweight, high-purity alumina-silica insulating material with low thermal conductivity and high strength properties.
CERMEX PR2300-U RCF PAPER is processed from washed fiber, thus having high uniformity and low shot content, which make it suitable for application as seals and gaskets. It can also be used in other thermal barrier applications. Figure 1 shows a refractory ceramic fiber paper from Mid-Mountain Materials.
