SG70 Application areas
for Structural Ceramic Sheet
Description
Introduction
SG70-130 is a dense, hard ceramic composite with several properties which make it very suitable for use as a safe replacement for asbestos cement board, micaceous or resin bonded boards. It has high mechanical strength at temperature, is not wetted by many metals and has good electrical resistance. It can be cut or machined with normal tools although carbide or diamond tips are recommended for large throughputs.
SG70-130 does not contain Refractory Ceramic Fibres (RCF) as defined in CHIP98. The homogeneous structure allows SG70-130 to be drilled and threaded either perpendicular or parallel to the board surface.
SG70-130 does not outgas under vacuum and is resistant to super alloy or glass spillage.
SG70-130 can be varnished to give an adequate seal if it needs to be used in an application where there is normal air pressure on one side or edge and vacuum on another.
