iFR Polyester

When the heat is on

Inherent Flame Retardant (iFR) Polyester is an industrial filament yarn for technical textiles and reinforcement of mechanical goods. iFR Polyester combines non-toxic flame retardant performance with lower shrinkage and higher tenacity.


In general, iFR Polyester helps support shorter afterburn times, shorter burn lengths, lower smoke gas densities, and lower flame propagation. This multifilament polyester yarn is also stronger and more durable than textile-grade polymers. The unique flame retardant properties can even be custom engineered to meet required codes and classifications.


  • Inherent FR anchored in polymer chain
  • Shorter after burn times/lengths
  • Lower smoke density
  • Maintain iFR and tensile properties during process
  • Less coating means lighter weight solutions
  • FR & Colour Development Opportunity
