Manufactured articles endowed with high characteristics of low-temperature plasticity, based on polytetrafluoroethylene or tetrafluoroethylene copolymers, and pastes for their preparation. |
摘要 |
<p>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.</p> |
