Oxidized PAN Fabrics: Non-Combustible, Non-Melting Industrial Protection
Our Oxidized PAN (pre-oxidized polyacrylonitrile) fabrics represent the pinnacle of high-performance flame-retardant textiles. Featuring an LOI (Limiting Oxygen Index) of over 45%, this material offers permanent fire resistance. Unlike chemically treated fabrics, Oxidized PAN
never melts, softens, or drips when exposed to extreme heat or open flames, effectively eliminating the risk of secondary burns.
With superior thermal stability and textile flexibility, it serves as a safer, skin-friendly alternative to asbestos and fiberglass, making it the standard choice for welding protection and industrial insulation.
Key Features
- Inherently Flame Retardant (LOI > 45%): Fire resistance is intrinsic to the fiber's molecular structure, not a surface coating. It remains effective after repeated washing and cannot burn in normal atmospheric conditions.
- Non-Melting Performance: Upon exposure to fire, the fabric carbonizes and thickens, forming a robust carbon shield that maintains structural integrity and prevents flame penetration.
- Skin-Friendly Comfort: Unlike fiberglass fabrics, Oxidized PAN is soft to the touch and non-irritating, making it suitable for direct skin contact in protective gear.
- Superior Thermal Insulation: Extremely low thermal conductivity effectively blocks heat flow, ensuring the safety of both personnel and critical equipment.
International Standards Compliance
Our Oxidized PAN fabrics are engineered to meet the world’s most rigorous industrial safety requirements. The products comply with key standards including
EN ISO 11611 (Welding Protection),
EN ISO 11612 (Heat & Flame Protection),
EN ISO 14116 (Limited Flame Spread), and
NFPA 2112 (Flash Fire Protection), providing industry-proven safety you can trust.

Frequently Asked Questions (FAQ)
Q: How is this different from standard FR Cotton?
A: FR Cotton is typically chemically treated, meaning its fire resistance can degrade with washing, and it may eventually burn through at extreme temperatures. Oxidized PAN is inherently flame retardant with an LOI of 45+. It will never burn or drip, regardless of washing, offering a higher level of protection.
Q: Can I use this for welding blankets?
A: Absolutely. Oxidized PAN is the standard material for high-end welding blankets. It effectively resists welding sparks and slag splatter while being more durable and softer than fiberglass blankets.
Q: Is the fabric available only in black?
A: Yes. The oxidation process alters the molecular structure of the fiber, turning it permanently black. This color is a visual indicator of its heat-resistant properties, and the material is extremely difficult to dye.
