Vacuum Formed Boards
YAO XING boards are high performance insulation products
manufactured from ceramic fiber (or with alumina fiber) and binders,
with YAO XING’s unique shot removing and vacuum forming process,
providing excellent high temperature stability, extra low thermal conductivity,
high compressive strength.
YAO XING boards can be easy to saw, drill and die-cut,
used as hot-face or back-up thermal insulation
in various high temperature applications in furnaces, kilns etc.
Additional hardness and strength can be reached with post treatments.
Available in variety of compositions, densities, sizes and post treatments combinations,
YAO XING board is one of the most versatile products available to the industry today.
