aluminium sheet and thermostability soft matting material etc..

Needle felt of basalt fiber

On the needle felt of basalt fiber, the basalt single fiber penetrate interlacing out-of-order to form structure of on-orietatio threee-dimensional aperture.Owing to adopt thinner fiber of 7-9um,bigger than the superficial area .void fraction is about 80%,no boron,it can be used for filtrating and purifying of high-quality air,thermal inisulation and sound-absorbing,heat insulator, steels of hot rolling mirror surface,aluminium sheet and thermostability soft matting material etc.
