Product Description Graphite felt, also known as graphite fiber felt, is mainly used as a thermal insulation and refractory material for various industrial furnaces including single crystal furnaces, carbonized furnaces, quartz furnaces, vacuum furnaces, thermal balance reaction furnaces, heat treatment furnaces, sintering furnaces, welding furnaces, and high-pressure furnaces for metallurgy, machinery, and chemical engineering industries. It is also used as a filter material for high-purity corrosive chemical reagents.Graphite felt has a carbon content of over 99%, which is higher than carbon felt. Under non-oxidizing atmosphere conditions, its working temperature can be over 2000 °C. It works with graphite composite boards and graphite special-shaped parts to form the insulation layer of industrial furnaces.Graphite felt is divided into soft graphite felt and rigid graphite felt. In addition, carbon felt before high-temperature graphitization is also an excellent high-temperature thermal insulation material and has good adsorption properties for inorganic gases.Soft Graphite Felt - Flexible Refractory Insulating MaterialHigh purity, high thermal stability.Low thermal conductivity coefficient, no static electricity.Easy cutting and machiningSoft graphite felt is a flexible insulating material for high temperature applications in inert or vacuum atmosphere and is entirely made of carbon fibers. When used as an insulation material for high-temperature industrial furnaces, it can be bound and stitched with carbon ropes woven through special process. Due to its controlled internal structure and electrical conductivity, soft felts can also be used for energy storage like redox flow cells. Soft graphite felts are divided into PAN-based soft graphite felts, rayon based soft graphite felts, and soft felts for battery.The base material for the production of carbon and graphite soft felt is felt made of needled cellulose fibers. They are processed into carbon soft felts by thermal treatment at temperature 800-1000°C. If these felts are treated at higher temperatures >2000°C, they become graphite soft felt. Rigid Graphite Felt - Thermal Insulation Materials for Industrial FurnacesTypical properties of rigid graphite felt:High temperature stability.Low thermal conductivity good thermal insulation effect.thermal shock resistance.Erosion resistanceRigid felt is a rigid insulation material with low thermal conductivity based on carbon fibers. A carbon based bonding material locks the fibers in a rigid structure, that can be offered in any shape (for example, plates, cylinders, barrels, disks). Rigid felt is produced by mixing and pressing of fiber material and binder, followed by high temperature treatment at temperature up to 2800 °C. In the final production step the rigid felt is machined to the desired dimensions.Surface coating can be: CFC, graphite foil or carbon cloth. Rigid graphite felt is generally divided into pitch-based rigid graphite felt, PAN-based rigid graphite felt and rayon-based rigid graphite felt. Comparing with rayon-based rigid graphite felt, PAN-based rigid graphite felt has bigger strength, better oxidation resistance, higher density, but weaker flexibility, better insulation properties.Technical Data of Graphite Soft Felt: MaterialPAN-CFRayon Graphite FeltVolume density ( g/cm3)0.1-0.160.10-0.12Carbon Content (%)≥99≥99Thermal conductivity(800oC)W/mk0.13-0.310.09-0.21Ash ( %)≤0.05≤0.02 Processing temperature (oC)≥2200≥2200Operating Condition in the air(oC)≤400 in the vacuum (oC)≥2200in the inert atmosphere (oC)≥3400Technical Data of Graphite Rigid Felt: MaterialPAN-CF Graphite Rigid FeltPAN-YZ Interger Graphite Rigid FeltRayon Graphite Rigid FeltVolume density ( g/cm3)0.16-0.35 can be adjusted0.14-0.21 can be adjusted0.18-0.23 can be adjustedThermal conductivity(800oC)W/mk0.2-0.30.12-0.250.12-0.25Carbon Content ( %)≥99≥99≥99 Processing temperature (oC)≥2200≥2200≥2200Operating Condition in the air(oC)≤400 in the vacuum (oC)≥2200in the inert atmosphere (oC)≥3400Technical Data of Graphite Material: Isostatic GraphitePropertyKBD-5KBD-6KBD-7KBD-7BKBD-8UnitApparent Density 1.851.901.821.821.90g/cm3Max Grain Size13-158-108-1013-158-10μmAsh value ≤500≤500≤500≤500≤500ppmSpecific Electrical Resistivity8-108-911-1311-1311-13μΩmFlexural Strength 4655515960MpaCompressive Strength 8595115121135MpaShore Hardness4853657070HSDThermal Expansion (room temperature to 600oC)4.754.85.85.85.8510-6/oCMolded Graphite PropertyKBG-4KBG-5Unit Apparent Density ≥1.80≥1.85g/cm3Ash value ≤500≤500ppmShore Hardness≥40≥45HSDSpecific Electrical Resistivity ≤12≤12μΩmFlexural Strength 3841MpaCompressive Strength 8187MpaMax Grain Size 2525μmVibration GraphitePropertyTSKGSKUnitApparent Density≥1.70≥1.72g/cm3Max Grain Size ≤2≤0.8mmSpecific Electrical Resistivity8-10≤8.5μΩmFlexural Strength ≥12.5≥15MpaCompressive Strength ≥28≥35MpaPorosity≤24≤20%Ash value ≤0.3≤0.3%Advanced Production Equipments Strict Quality Control Ensures High Quality Products Safe Packing Question and Answer:Q:Are you a manufacturer or trading company?A:We are a manufacture for graphite material and graphite machined products.Q:How can you gurantee the quality?A:We have the most advanced equipments in our Lab and professional quality control team.We can gurantee each batch of the product with the stable quality.Q:Can you offer samples?A: Yes, we offer samples to testQ: Delivery time?A:Around 10 days.
