METHOD OF OBTAINING POLYMERIC COMPOSITIONS BASED ON POLYTETRAFLUOROETHYLENE CONTAINING MINERAL FILLER Russian patent published in 2017 - IPC C08J5/16 C08K3/34 C08K3/22 C08L27/18 

FIELD: chemistry.

SUBSTANCE: method of producing polymer compositions based on polytetrafluoroethylene involves pre-dispersing the mineral filler phlogopite and magnesium spinel in a planetary mill. Further, subsequent ultrasonic treatment is carried out in an environment of ethyl alcohol at a volume power of ultrasound of 3000 W for 15 minutes. Then, the products are manufactured by cold pressing, followed by free sintering and cooling.

EFFECT: use of the invention will reduce the rate of mass wear of the composite material up to 370 times and increase the relative elongation, and products based on it-the resource of machines and equipment.
