Boards
Tekfiber plates are rigid and high quality boards with low heat conduction coefficient which are produced from high purity raw materials such as synthetic alumina powder, pure silica sand, zircon sand.
Tekfiber plates produced from high
purity raw materials such as synthetic alumina powder, pure silica sand, zircon
sand are plates with low heat conduction coefficient.
High strength plates with ceramic fiber content and low heat conduction coefficient. It is produced from high purity raw materials such as synthetic alumina powder, pure silica sand, zircon sand. Thanks to this, they show superior mechanical properties and high temperature resistance.
