ABSTRACT:
Low melt viscosity polytetrafluorethylene (PTFE), i.e. having a melt viscosity of 50 to 1.times.10.sup.5 Pa.multidot.s at 372.degree. C., is combined with non-fluorinated thermally stable polymer such as polyarleneetherketone to provide melt-fabricability application for the low MV PTFE and provide improved properties for the thermally stable polymer.
