摘要 |
To provide an un-sintered polytetrafluoroethylene processed article which has an un-sintered polytetrafluoroethylene layer formed by coating and/or impregnating with an aqueous dispersion of PTFE and is characterized in that a content of alkyl phenols detected from the un-sintered PTFE layer is not more than 0.1 ppm. The un-sintered PTFE-processed article scarcely contains alkyl phenols which are suspected as chemical substances having endocrine disrupting activity.
