Which carbon felts do you recommend for furnaces?

Soft felt for flexible liners and conformable insulation; rigid felt for panels and stable structures. Choice depends on max temperature, atmosphere (vacuum, inert), and thermal cycle.

What this category includes

This line covers insulation, sealing and specialty carbon and graphite materials for furnaces, vacuum and rotating equipment.

Soft felt — flexible insulation for vacuum and inert atmospheres.
Rigid felt — structural high-temperature insulation.
Expanded graphite laminate — gaskets and sheets.
Braided packing — sealing for valves and pumps.
CFC panels — carbon-fiber carbon for high temperature.

State temperature, atmosphere and geometry so we can quote the right form.
