Orgasol® Powders
Adding Lubricity

Orgasol® powders can also be used as smoothing agent to help reduce the coefficient of friction and add lubricity to the final coating. These REACH-compliant polyamide powders are manufactured without the use of PFOA or any other PFAS, so they make an excellent alternative to PTFE waxes. Now formulators have a great alternative to PTFE waxes for reducing the coefficient of friction/slip aid and improving abrasion resistance while staying compliant with the changing regulatory landscape.

Coefficient of friction

As you can see in the chart below, a small amount of Orgasol® powder reduced the dynamic coefficient of friction to a similar level as that of the PTFE/PE wax evaluated.  Additionally, the Orgasol® powder at the same time imparts other great properties like abrasion resistance, gloss control, and stain & chemical resistance.  So when you need lubricity in addition to other properties, Orgasol® powders are a great option.

PTFE wax alternative

Why should you consider looking for an alternative to PTFE wax?

  • Certain PTFE waxes are produced with the use of PFAS surfactants
  • Because Orgasol® powders are manufactured without the use of PFOA or any other PFAS, these polyamide powders are compliant with European Union REACH Annex XVII (as of 4 July 2020).  This provides formulators with an alternative slip aid additive that also improves abrasion resistance while remaining compliant to current regulatory requirements.

Orgasol® powders as an alternative to PTFE wax

Arkema does not use PFOA or any other PFAS in the manufacturing of Orgasol® powders.  Additionally these powders have... 

  • European Food Contact and FDA approval :
    • Orgasol® 2001 UD NAT 2 and Orgasol® 2002 EXD NAT 1 are compliant with FDA 177-1500 and 175-300
  • Density close to 1: limited tendency to settle or float
  • Refractive index (1,52-1,53): limited haze
  • Smooth, surface with reduce coefficient of friction
  • Improved scratch and abrasion resistance
  • Limited impact on gloss (if adapted particle size is selected)
  • High temperature resistance (melting point at 177°C)
