FIELD: chemistry.
SUBSTANCE: invention relates to a mixture of polyphenylsulphone (PPSU) and polytetrafluoroethylene (PTFE) for manufacturing moulded products from a synthetic material, to a method of manufacturing the moulded products from the synthetic material and the application of the said mixture. The PPSU and PTFE mixture is characterised by the fact that the content of PTFE in the mixture constitutes from 1 to 15 wt %, and the content of PPSU in the mixture constitutes from 99 to 85 wt %. PPSU and PTFE are mixed with each other in an extruder at a temperature of 340°C. The obtained compound is granulated, granulate is extruded at a screw temperature from 370 to 390°C with obtaining the moulded products from the synthetic material. The obtained formed products from the synthetic material are applied as anti-wear tapes in pipelines for petroleum products.
EFFECT: obtaining the mixture for the production of tapes, reducing friction in pipelines for petroleum products.
