Exolit® 5060 PK
Organic non-halogenated phosphorus flame retardant
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.
- Highly stable in acidic and basic media as well as redox active conditions
- Alkylphenol ethoxylate-free
- Low impact on fibre production and viscose processing
- Special adaptations of the spinning process are not required
- Low impact on whiteness and light stability of treated textiles
- No negative impact on post-treatment procedures, including dyeing
- Hardly extracted by washing procedures, even under the demanding conditions of dry cleaning
- Non-halogenated flame retardant with favorable environmental and health profile
For regulatory details such as the classification and labelling as dangerous substances or goods please refer to our corresponding Material Safety Data Sheet.

- Reduced emissions of flame retardant material during use due to incorporation into fiber
- Contributes to saving lives and assets as a flame retardant
- Phosphorus is on the EU list of critical raw materials, however, recycling is possible and actively investigated
- Application of flame retardant viscose enables use of renewable raw materials (cellulose from wood) for protective garments
- Can be applied during fiber production and thus ensures increased material efficiency due to incorporation into the viscose fiber
- Reduced waste in production through high yield and recycling of raw materials
- Drop-in solution for viscose process
- Complies with fire safety standards such as DIN 4102-1, class B2
- Constant high quality and hydrolytic stability
- Supports the attainability of eco-labels for customer products
- Wearing comfort is improved by the application of viscose garments with Exolit 5060 PK versus other materials
- Long lasting flame retardancy effect and washing resistance
- Lower influence on whiteness of fibers and higher light stability compared to polyaramid fibers
