Pre-oxidized fiber, also known as oxidized PAN fiber, is a high-performance flame-resistant fiber produced from polyacrylonitrile (PAN) precursor through a controlled oxidation process.
During oxidation treatment, the molecular structure of the fiber becomes highly stable, providing excellent thermal resistance, flame retardancy, and dimensional stability under high temperature conditions.
Compared with traditional synthetic fibers, pre-oxidized fiber offers superior performance in extreme heat environments, making it an ideal material for high temperature insulation, fire protection, and industrial thermal management applications.
YUEXIN provides customized pre-oxidized fiber felt and carbon fiber composite insulation materials using advanced needle punching technology for various industrial applications.
Pre-oxidized fiber is widely used in demanding environments because of its unique characteristics:
Pre-oxidized fiber has inherent flame-resistant properties and does not easily melt or drip when exposed to high temperatures.
It is suitable for applications requiring:
Fire protection
Thermal barriers
Heat shielding
Protective insulation
Pre-oxidized fiber maintains structural stability under elevated temperatures.
It is commonly used in:
Industrial furnace insulation
Heat treatment equipment
High temperature protection systems
Thermal insulation components
Pre-oxidized fiber felt provides effective thermal insulation by reducing heat transfer.
The lightweight fibrous structure helps create air insulation layers, improving energy efficiency in industrial applications.
Compared with traditional rigid insulation materials, pre-oxidized fiber felt offers:
Low weight
Excellent flexibility
