Functional Fluid


​BLUESIL FLD 21650 has been developed for formulation into emulsions destined for use in textile applications.

When applied to textiles it imparts properties of a good compromise between softness and hydrophilicity, whilst remaining non-yellowing due to the presence of HALS groups.​

BLUESIL FLD 21650 is easily emulsified into micro- or macro-emulsions, using typically C13 [EO]6 alcohol ethoxylated surfactants.

The application onto textile surfaces imparts the following properties:

  • Non-yellowing even at high temperatures.

  • Very good soft handle.

  • Good compromise softness / hydrophilicity.
