Soft Felt - Graphite Felt Definition Of Graphite Felt
OUR Soft Graphite Felt becomes graphite felt after being treated
under high temperature above 2000 ℃ under vacuum or inert
atmosphere, its carbon content is higher than carbon felt, up to
99%.
Soft Graphite Felt Technical index: | Item | Polypropylene cyano graphite felt | Viscose-based graphite felt | | Bulk density(g/cm) | 0.1~0.15 | 0.05~0.15 | | Area density(g/cm) | 600~1200 | 300~600 | | Carbon content(%) | ≥99 | ≥99 | | Ash content(%) | 0.05~0.1 | 0.5~0.6 | | strength(N⊥) | 60~70 | 5~10 | | (Sample50×,200,∥) | 150~200 | 10~20 | | Thermal conductivity(W/m,k) | 0.06(34.6℃) | |
- Graphite Felt Specifications
| Specifications | Polypropylene cyano graphite felt | Viscose-based graphite felt | | length(mm) | ≥1500 | ≥2000 | | width(mm) | 400±,10 | 400±,10 | | thickness(mm) | 5~15 | |
Performance And Application The main use of Soft Graphite Felt is as a thermal insulation
material for single crystal silicon smelting furnace. In the
chemical industry, it can be used as a filter material for high
purity corrosive chemical reagents. Polyacrylonitrile-based Soft Graphite Felt is stronger and more
resistant to oxidation than viscose-based graphite felt, graphite
felt has poor flexibility, large bulk density, and good thermal
insulation performance. In addition to their high purity, high-temperature resistance,
corrosion resistance, and non-melting characteristics, Soft
Graphite Felt also have the advantages of elasticity, foldability,
tailoring, and sewing with graphite yarn.
