METHOD OF PROVIDING FRIABLE POLYTETRAFLUOROETHYLENE PRODUCTS |
摘要 |
A method is disclosed for providing a friable polytetrafluoroethylene (PTFE) product that has particles of a desired size which are flowable and do not tend to agglomerate. To achieve this result, the PTFE starting material is handled at a temperature below 66 ~F, and preferably below 55 ~F, before irradiating. The PTFE starting material may be mixed with a wetting agent before irradiating to provide a product that has enhanced dispersibility. The source of radiation may include electron beam radiation, nuclear radiation, or radiation from a cobalt-60 (Co60) source. |
