Our flame retardants for textiles & fibers -
tailored halogen-free solutions for safer fabrics and clothes

Providing better fire safety to homes and those who protect them

Textiles and fibers make homes nicer to live in but, if not properly protected, can create high fire risks. For the apparel of those with occupational fire risks – like firefighters, oil workers and military personnel – protection is vital.

Our halogen-free Exolit® solutions for textiles and fibers provide fire safety without creating new risks by using hazardous legacy compounds. Our offering includes tailor-made flame retardants for the production of viscose/rayon fibers as well as high-performing ingredients for protecting fabrics and artificial leather.

A great fit for health, the environment - and your products

Incorporating our Exolit® 5060 products into viscose/rayon fibers significantly reduces their flammability. The effect is durable and does not affect spinning or later processing and finishing steps. Fibers protected with our Exolit® 5060 press cake or ready-to-use dispersion can resist fire even after many washing and dry-cleaning cycles.

When it comes to back-coating fabrics or protecting materials like artificial leather, our Exolit® AP and OP lines provide great fits. Several carry our sustainability label EcoTain®, and under our OP Terra brand, we offer identical chemistries from bio-based sources.

A powerful padding against fire

Our Exolit® 5060 can be incorporated into viscose even before fiber spinning. Our Exolit® AP and OP lines, on the other hand, are particularly attractive to customers impregnating fabrics by padding in foulard machines, followed by drying and other steps. They can also be used for back-coating with acrylic or polyurethane-based coatings.

Sustainable fire protection, key benefits of our solutions for textiles & fibers


Exolit® 5060 offers a unique solution for viscose/rayon fibers, designed to resist extreme pH conditions during processing


Exolit® OP 930 is active in both the solid phase and the gas phase, making it a great fit for textile back-coatings


Exolit® AP 422 provides a cost-efficient, non-halogenated, phosphorus-based flame retardant for textile coatings and coverings

Textiles need sustainable and innovative flame retardants Thomas Mayer-Gall explains why

»In the face of increasing bans on halogenated flame retardants, the textile industry is looking for alternatives offering the same level of safety. Together with innovative partners like Clariant, we are exploring options that are safe for humans and the environment, as well as bio-based and biodegradable.«

Made-to-measure products for textile needs

  • Exolit® 5060 PK
    Clariant´s Exolit 5060 PK is an organic non-halogenated phosphorus flame retardant, especially designed for incorporation into viscose fibres. It is supplied as a wet presscake of 2,2'-oxybis [5,5-dimethyl-1,3,2-dioxaphosphorinane]-2,2'-disulfide.
  • Exolit® OP 930
    Exolit OP 930 is a white, fine-grained powder based on an organic phosphinate. The product is not hygroscopic and it is insoluble in water and common organic solvents like acetone, dichloromethane, MEK, toluene. Exolit OP 930 can easily be dispersed in solvents like acetone or MEK. For more details see our Innovation Spotlight video.
  • Exolit® AP 422
    Exolit AP 422 is a fine-particle ammonium polyphosphate (phase II) produced by a special method. The product is largely insoluble in water and completely insoluble in organic solvents. It is colorless, non-hygroscopic and non-flammable.
