Viscose-basedcarbon felt and graphite felt
（1）Productdescription
Viscose-based carbon fiber felt is madeof viscose rayon as rawmaterial, and is a high-temperature insulation materialwith excellentperformance. It has the general characteristics of other kindsof carbon felt,but also has the characteristics of low density and low thermalconductivity, soit is suitable for heat insulation and insulation materials.Ablative material.It is especially suitable for the medium frequency inductionhigh temperaturesintering furnace and the situation where the heatpreservation performance isstricter. It is also suitable for the heatingmaterial of quartz heating pipeand the felt for marking machine.
