artifacts with high plasticity afreddo, based on polytetrafluoroethylene or copolymers of tetrafluoroethylene, and paste for their preparation.

摘要

An extrudable paste prepared by starting from aqueous dispersions of tetrafluoroethylene (TFE) homopolymers or copolymers with comonomers amounts lower than 0.5% by weight, a paraffin oil (vaseline) or silicone oil, a coagulating liquid and optionally graphite, which makes it possible to obtain, by extrusion, a rod endowed with high characteristics of low-temperature plasticity, which does not show the occurrence of longitudinal fractures when submitted to a pressure in the transversal direction.
