Silica
Silica Fibre
Silica fibre is a thermal insulating material produced by melting and spinning silica sand.
Its fibrous structure gives it remarkable flexibility and mechanical strength, while maintaining high purity.
This makes it an essential component in many industrial sectors where performance under extreme conditions is required.
