Hunan MTR New Material Technology Co., Ltd. has perfect production technology and equipment, we can customize products of various sizes and shapes to meet your needs for various vacuum and high temperature furnace insulation materials. Sincerely welcome your inquiries.
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.
