August 19, 2021

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.

Benefits

  • 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

PeoplePEOPLE
PeopleSAFE USE, TRANSPARENCY AND INFORMATION
  • Reduced emissions of flame retardant material during use due to incorporation into fiber
PeopleADDRESSING MEGATRENDS AND SOCIETAL NEEDS
  • Contributes to saving lives and assets as a flame retardant
PeoplePLANET
PeopleRAW MATERIALS AND SUSTAINABLE SOURCING
  • 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
PeopleRESOURCE EFFICIENCY AND ENVIRONMENTAL PROTECTION
  • 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
PeoplePERFORMANCE
PeopleINTEGRATED SUSTAINABLE BUSINESS
  • Drop-in solution for viscose process

 

 

PeoplePERFORMANCE ADVANTAGES
