Non-halogenated Flame Retardant for Viscose Fibres

Exolit® 5060 DP

Exolit 5060 DP is a finely dispersed aqueous dispersion which is ideally suitable for incorporation into the viscose spinning mass. The active ingredient Exolit 5060 DP is an organic, non-halogenated phosphorus compound. Exolit 5060 DP significantly reduces the flammability of the finished fibres. The effect is highly permanent and does not affect spinning and subsequent processing or finishing steps of the fibres. The level of active substance (Exolit 5060 DP) incorporated in the fibres determines the flammability, measured by the Limited Oxygen Index (LOI).
