ABSTRACT:
A Process is described in which the polymer is passed over a former under hydro-static pressure, which may involve passing the material over a die or series of dies for the purpose of imposing multi-axial expansion to the workpiece. Some of the advantages are increased stiffness and reduction in creep. Improved wear is also found.
