Viscose-based soft graphite felt
Product Description Viscose-based carbon fiber felt is made from viscose rayon as the raw material. It is a high-performance thermal insulation material with excellent properties. It has the general characteristics of other types of carbon felt, along with features such as low density and low thermal conductivity, making it suitable for thermal insulation and ablation-resistant materials. It is especially suitable for medium-frequency induction high-temperature sintering furnaces and applications with stringent insulation performance requirements. It is also suitable for use as heating element material for quartz heating tubes and felts for marking machines.
