Abstract
The invention relates to a low-fibrillation molded body containing a tape (1) essentially consisting of polytetrafluoroethylene, characterized in that the tape is composed of at least four plies (7,8,9,10) of essentially equal width arranged essentially parallel to each other, said plies being obtainable by folding.
Claims13
A low-fibrillation molded body containing a tape (1) essentially consisting of polytetrafluoroethylene, characterized in that the tape is composed of at least four plies (7,8,9,10) of essentially equal width arranged essentially parallel to each other, said plies being obtainable by folding.
A low-fibrillation molded body containing a tape (1) essentially consisting of polytetrafluoroethylene, characterized in that the tape is folded on both edges (2,3) and, in the folded state, both edges (2,3) are located close to or at the longitudinal axis (6) of the tape.
A molded body according to any of the preceding claims, characterized in that the tape (1) exhibits an essentially uniform width and thickness across its length.
A process for the manufacture of a molded body according to any of the preceding claims, comprising the steps of
- a) providing a tape (1) essentially consisting of polytetrafluoroethylene, which tape has two original edges (2,3),
- b) folding the tape (1) on both original edges (2,3) so that, after the folding, the original edges (2,3) end up lying essentially parallel to each other and close together, preferably adjacent to each other, and two new edges (4,5) are formed,
- c) optionally at least one further folding at the longitudinal axis (6) of the tape (1) so that, after the folding, the previously formed new edges (4,5) end up lying essentially on top of each other.
