Processing polytetrafluoroethylene comprises e.g. mixing non-flowing polytetrafluoroethylene-raw material with low-boiling or high-boiling liquid or liquid mixture, grinding and drying mixture or sedimented polytetrafluoroethylene

摘要

Processing polytetrafluoroethylene (PTFE) comprises mixing at least one non-flowing PTFE-raw material with at least one low-boiling, high-boiling or higher boiling liquid or liquid mixture, where the amount of low-boiling, or high-boiling or higher boiling liquid or liquid mixture is measured after, the surface of the PTFE-raw material is contacted and/or wetted by the liquid, subsequently compressing, grinding and drying the mixture, or introducing the mixture into a water bath or adding water to the mixture, separating, compressing, grinding and drying the sedimented PTFE. Processing polytetrafluoroethylene (PTFE) comprises mixing at least one non-flowing PTFE-raw material with at least one low-boiling, high-boiling or higher boiling liquid or liquid mixture, which is miscible with water and/or is water-soluble, where the amount of low-boiling, or high-boiling or higher boiling liquid or liquid mixture is measured after contacting and/or wetting the surface of the PTFE-raw material with the liquid, and compressing, grinding and drying the mixture, or introducing the mixture into a water bath or adding water to the mixture, separating, compressing, grinding and drying the sedimented PTFE.
