The basic types of molding powders are those for compression molding and ram extrusion molding. These are processed at ambient temperature followed by sintering above the crystalline melting point. Possessed with advantages like excellent creep resistance, large tensile elongation, excellent electrical insulation while readily machinable to complex forms, foldable, stretchable and modified PTFE is also weldable with longer flexural life than conventional grades. The following grades are available in order to suit various molding methods.
