Carbon fiber felt has stable performance, strong chemical resistance, good seismic performance, easy to process into any shape, easy to install and use in various equipment, the maximum use temperature can reach 1800 ℃ -2700 ℃ under vacuum or inert atmosphere, it is an ideal thermal insulation material for various vacuums.

Technical index:

Specifications:

Length (m) ≤20

Width (m) ≤1.4

Thickness (mm) 3-18

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:

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 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.

Hunan MTR New Material Technology Co., Ltd. (formerly Zhuzhou Green Carbon Fiber Products Co., Ltd.) is a high-temperature furnace thermal insulation material production plant! Our company adheres to the corporate philosophy of singularity, focus and professionalism, and is committed to the continuous development and application of thermal insulation material technology.

The company’s main products include graphite hard felt, reinforced composite hard felt, multi-type composite hard felt (made in an overall shape), graphite felt, high-temperature carbon felt, and other thermal field insulation materials. The rigid felt series have a rigidity that traditional insulation materials do not have.
