Abstract
The structure of ultrafine polytetrafluoroethylene (PTFE) powder obtained via waste PTFE thermal treatment by superheated steam was studied. The condensation of the resulting gaseous pyrolysis products has been performed with the use of water. The features of molecular and morphological structure of the powder have been established, the potentialities of its practical application have been revealed. The technology allows processing the wastes on the industrial scale to obtain commercial product, thus solving one of the problems of fluoropolymer production.
