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.

Understanding the Difference Between Thermal Insulation and High Temperature Insulation Thermal insulation materials serve a fundamental purpose across a vast range of engineering and construction applications: preventing unwanted heat transfer between a system and its surroundings, whether the goal is keeping heat in or keeping heat out. However, within this broad category, a critical distinction separates general-purpose thermal insulation materials — used in building envelopes, refrigeration...
