Abstract
Official abstract text for this publication.
A molding material including a melt-fabricable fluororesin and having a metal content of 100 ng/1 g or less as measured by an ashing method. Also disclosed is a tube made of the molding material.
First claim
Opening claim text (preview).
The invention claimed is: 1. A tube made of a molding material comprising a melt-fabricable fluororesin and the whole of the molding material having a metal content of 40 ng/1 g or less as measured by an ashing method, wherein the fluororesin is at least one selected from the group consisting of a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer and a tetrafluoroethylene/hexafluoropropylene copolymer, wherein the fluororesin has a melt flow rate of 1 to 6 g/10 min, and wherein the whole of the molding material has a Na content of <1 ng/1 g and a K content of <1 ng/1 g as measured by an ashing method. 2. The tube according to claim 1 , wherein the molding material is a pellet. 3. The tube according to claim 1 , wherein the fluororesin is a fluororesin subjected to fluorination treatment.
