Pre-oxygen fibers, also known as pre-oxidized fibers, are intermediate products in the production process of carbon fibers. It is made of polyacrylonitrile (PAN) fibers after pre-oxidation treatment at 200-300°C, and has unique high temperature resistance, flame retardant and dimensional stability. Compared with ordinary fibers, pre-oxygen fiber fabrics will not melt and drip under high temperature environments, and the limit oxygen index (LOI) is as high as 38%-55%. They are flame-retardant materials and can effectively reduce fire risks.

Core advantages: safe, durable, environmentally friendly

Excellent high temperature resistance: Pre-oxygen wire can be used for a long time in an environment of 200-300℃, and its short-term temperature resistance is as high as 1600℃, far exceeding ordinary flame retardant fibers.

Excellent flame retardant effect: does not burn when exposed to fire, only slowly carbonizes, no melting droplets, effectively reducing secondary damage.

Stable chemical properties: acid and alkali resistance, corrosion resistance, suitable for harsh industrial environments.

Green and environmental protection: There is no release of harmful substances during production, and it complies with international environmental protection standards such as the EU REACH.

Wide application fields and huge market potential

Fire protection and safety protection: fire protection clothing, high-temperature working clothing, welding protective supplies, etc.;

Aerospace: aircraft interior, thermal insulation layer, composite reinforced substrate;

Industrial filtration: high-temperature smoke filter bags, corrosion-resistant filter materials in the chemical industry;

New energy and environmental protection: lithium battery separators, high-temperature sealing materials, etc.
