Composition including a fluoroelastomer and a thermoplastic polyamide

Apparatus for conveying continuous collapsed film includes a guidance arrangement receiving the continuous collapsed film, the guidance arrangement including at least one guide roller and at least one turning bar for guiding the film. The at least one guide roller changes the direction of the film 180 degrees, and the at least one turning bar changes the direction of the film 180 degrees. A conveyor belt travels the same speed as the film and the conveyor belt and the film loop over the one turning bar in superimposed relationship with the conveyor belt being between the at least one turning bar and the film such that the conveyor belt carries the film during the looping over the at least one turning bar.

Apparatus for conveying collapsed, continuous plastic films

An extruded thermoplastic polymer conduit having a conduit wall of substantially uniform crystalline morphology through the entire thickness thereof free of any oriented surface zone and the process of making such conduits.

Extruded conduits and method of making the same

An extruded thermoplastic polymer conduit having a conduit wall of substantially uniform crystalline morphology through the entire thickness thereof free of any oriented surface zone is formed by heating to melt the surface zone and cooling to recrystallize the surface zone.
