It can be cut according to customer requirements.
Application:
Used as heat insulation material of high-temperature vacuum furnace, used as reinforcement material, and made carbon/carbon composite material.
Features:
- Small volume ratio: the volume ratio of our special carbon felt is 0.08-0.12g / cm3, the general acrylic carbon felt volume ratio is 0.15-0.17 g / cm3, the same specification of carbon felt is lighter;
- High strength: The production process and method are improved. The fiber is oxidized and drawn, the strength is ≥200Mpa, and the Acrylic fiber fineness is 1.22dtex, much smaller than ordinary acrylic, so the fiber strength of the felt raw material before carbonization is increased.
- During further high-temperature carbonization, the shrinkage and weight loss are less than about 50% of ordinary acrylic carbon felt, and the width reaches 1.50 meters.
- Carbon felt is soft: flexible, foldable, and not easily deformed by twisting.
- Clean Appearance: the carbon felt has no carbon black appearance, and will not produce carbon foam and carbon slag due to operation, and is not prone to harsh environmental problems.
- According to the customer's purpose, it can produce the carbon felt of its related industries (for structural materials, thermal insulation, conductive).
Application:
thermal insulation materials such as vacuum sintering furnace, single crystal furnace resistance furnace, high-pressure furnace, induction furnace, etc; carbon-carbon composite, carbon-carbon structure enhancement, carbon-carbon graphite material; conductive carbon, shielding, heating carbon material.
Carbon felt can be used in vacuum furnaces and inert gas furnace insulation materials, hot gas or liquid and molten metal filters, fuel cell porous electrodes, catalyst carriers, corrosion-resistant container composite linings, carbon-carbon composite materials, and electric heating.
