Ceramic fiber insulation foams are categorized based on their composition and manufacturing processes. The main types include: 1) Calcium Silicate Foam, which is made from calcium silicate and offers good thermal insulation properties. 2) Alumina Silicate Foam, known for its high-temperature resistance and chemical stability. 3) Mullite Foam, a high-temperature variant with excellent mechanical strength. 4) Zirconia Foam, which has superior resistance to corrosion and high-temperature environments. 5) Silica Foam, characterized by its low thermal conductivity and resistance to heat. Each type has specific applications based on the temperature range, chemical resistance, and mechanical strength required for the insulation application.
