Conventional Composite Hard Felt - Sheet

Characteristic:

Polyacrylonitrile-based carbon felt is a kind of 3-16mm thick felt made of polyacrylonitrile-based original felt after thermal stabilization and carbonization treatment. Since 90% of carbon felt is pores, it has excellent thermal insulation performance in vacuum or inert atmosphere,especially under high-temperature conditions, it has the characteristics of light weight, small specific heat capacity, soft texture, good thermal insulation, easy operation, etc. It has stable performance and is especially suitable for intermittent operation of high-temperature vacuum furnace, which can save a lot of energy.

Features:

strong anti-radiation ability, long service life, energy saving, No pollution in hot cell, pressure resistance, resistance to airflow impact, good insulation, Lifespan is 3 times that of soft felt
