FLUORORESIN TUBE AND PROCESS FOR PRODUCING THE SAME

摘要

A large-diameter thin-walled fluororesin tube that even when the diameter is large (for example, 100 mm or greater f), exhibits excellent wall thickness accuracy and low orientation; and a process for producing the same. In particular, there is disclosed a fluororesin tube of 70 µm or less average thickness and 100 mm or greater outer diameter wherein the thickness variation of the tube falls within ±20% of the average thickness of the tube and the degree of orientation (F) of the tube is in the range of 0.25 to 0.55.
