Alumina Ceramic Fiber Felt
Introduction
The NC fiber felt is made by using loose cotton combined with organic and inorganic binders, and formed through wet vacuum filtration. This product has elasticity, toughness, and semi-rigidity without dust. Due to the use of fire-resistant fibers with stable chemical properties, it is lightweight and has a good thermal insulation effect. It is a versatile product that can meet the complex needs of many industries.
Characteristics
The product features low thermal conductivity, heat resistance, high flexibility, good sound insulation, and corrosion resistance.
Application
The product is used as a sealing material for furnace doors and expansion joints; insulation and electrical insulation materials for heating devices in instruments;high-temperature sealing gaskets; glass and enamel; ladle covers and hot blast stoves;anti-abrasion parts inside furnaces.

A vacuum furnace is a high-tech industrial oven used for heat treatment processes, primarily in the manufacturing and processing of metals, ceramics, and other materials. The furnace operates in a controlled vacuum environment, meaning that the air is removed from the chamber, creating a low-pressure atmosphere. This unique condition allows for specific and often superior material properties to be achieved during the heating process. Let’s dive deeper into the purpose of a vacuum furnace and why...
