Zirconia Fibre

Zirconia fibres products have high temperatures strength and a high resistance against chemical agents. Zirconia fibre has the lowest thermal conductivity of any refractory fibrous products available on the market. The maximum use temperature is 2200°C and the melting begins at 2500°C (depending on the products). The fabrics are constructed of continuous individual filaments and don’t require organic binders.
