Name:

Carbon Fiber Felt
Carbon Fiber Felt
Introduction
Carbon fiber felt has the performance of high temperature and fire prevention, widely used in various high temperature
vacuum furnace for heat insulation, also can be made to carbon composites. Because 90% interspace of carbon fiber felt,
it has superior heat insulation in vacuum or inert gas under high temperature environment, stable heat insulating
performance, soft, small heat capacity, conveniently operation.
This product used PAN fiber as raw materials, needle felt, through oxidation, carbonization and graphitization etc,
processed into high temperature and heat insulation material.
