Laurel’s Ultraflon range comprises a selection of polytetrafluoroethylene (PTFE) and fluorinated ethylene-propylene (FEP) powders. These are available in friable and non-friable forms. There are also a selection of different particle size distributions; from sub-micron to 100’s of microns. PTFE micro powder is commonly used in grease and dry film lubricant formulations as a solid lubricant.

There are several grades which have NSF-HX1 approval for indirect food contact greases. Non-stick coatings utilise PTFE micro powder due to the low coefficient of friction that it imparts to the surface. Many of these applications also require specific food contact approvals which several of these grades have. PTFE micro powder imparts slip properties at the surface. As such, coatings formulated with Ultraflon have excellent abrasion and scuff resistance.

Features


    • Selection of particle size distributions available. Average PTFE particle size (d50) ranges from sub-micron to 100’s of microns

    • Friable and non-friable grades available

    • Surface modified PTFE grades which are readily dispersible in water

    • FDA food contact and NSF-HX1 approvals for certain grades

    • Different viscosity builds attainable – from low to high impact

    • Low and high molecular weight PTFE grades available

Benefits


    • Solid friction modifier in grease formulations to lower surface wear and seal imperfections

    • Fantastic chemical resistance for engineered polymers, coatings and greases

    • Excellent slip properties when formulated into coatings and inks. This improves abrasion resistance

    • Certain grades have a low impact on viscosity. Others increase viscosity. Aqueous PTFE dispersions can be easily made with hydrophilic surface-modified powders. This saves the need for complicated and expensive dispersant packages. It also saves money over pre-dispersed products where you are “paying for the water”

    • Storage stability is less of an issue as you can make the dispersion on demand when needed

    • Flagship products are very commercially attractive

    • Certain grades can be used in cookware and food safe lubricants due to their regulatory approvals

Typical Applications


    • Solid lubricant for dry film lubricant formulations. Includes products dispensed via aerosol

    • Friction modifier in grease formulations

    • Non-stick coatings

    • PTFE gives a low coefficient of friction and excellent release properties

    • Imparting slip to inks and coatings to improve abrasion resistance

    • Engineered polymers for chemical resistance and slip
