LiFRA® , the flame retardant PET fiber, has added special phosphonium flame-retardant without halogen during polymerization process. This fiber is difficult to be ignited and will slightly shrink and massed into conglobation when encountering flames. LiFRA® is fireproof with extremely high safety and excellent flame-retardant effect.

Product Features:
*Permanent Flame-Retardant Effect : Since the flame resistant is added during the polymerization process , LiFRA® has the excellent flame retardation, durability, and waterproofing.
* Environment Friendly : LiFRA® will not produce the halogen toxic gas or chemical hazards in burning; it is really environment friendly material.
* High Limiting Oxygen Index (LOI) : As special phosphonium is added during polymerization process, LiFRA® has high Limiting Oxygen Index with excellent performance of flame retardation.
