Algoflon® L and Polymist® micronized powders are used as additives for coatings and greases in the Oil & Gas industry.

These materials are low molecular weight PTFE powders with small particle sizes that are used as additives in many different applications to enhance processing or end-use performance characteristics.

Polymist® powders, obtained through suspension polymerization, are composed of compact particles having sizes designed for the final application. Algoflon® L powders, obtained through dispersion polymerization, are agglomerates of smaller primary particles and for this reason they have higher specific surface area than Polymist® powders. All these micronized powders can be used at temperatures from –260°C to 260°C and have been designed to be easily dispersed in dry or liquid media.
