Reinforced Composite Hard Felt - Sheet
Features:
Our Reinforced Composite Hard Felt are flat plates, drums, dishes and other shaped parts, which are widely used in furnaces with high vacuum and inert gas, such as: single crystal growth furnace, polycrystalline ingot furnace, sapphire crystal growth furnace, cemented carbide (powder Metallurgy) vacuum sintering furnace, low-pressure sintering furnace, etc., the maximum operating temperature can reach 3000 ℃. In addition to its excellent thermal insulation efficiency,
Composite Hard Felt also has the characteristics of installation without support,
easy installation/removal, etc.,
which not only saves labor, but also reduces the replacement cycle.
The density of Reinforced Composite Hard Felt is 0.18-0.32g/cm3.
Composite Hard Felt has the advantages of high rigidity, self-supporting, high strength, no short fiber loss, and low thermal conductivity that traditional insulation materials do not have.
