  • Process for coating an electroconductive material using foamable solid compositions based on perfluoropolymers
    Patent number: 5716665
    Abstract: The invention relates to a foamable solid composition based on thermoprocessable perfluoropolymers comprising, homogeneously dispersed in the polymeric matrix, 0.05-20% by weight of a liquid fluoropolyether having molecular weight lower than 3,500 and 0.002-10% by weight of a nucleating agent. The composition results to be suitable for extruding foamed cables.

  • Process of making multifilament yarns of thermoplastic polymers based on tetrafluoroethylene
    Patent number: 5618481
    Abstract: A multifilament yarn of a thermoplastic polymer based on tetrafluoroethylene, having high mechanical strength and dimensional stability at high temperatures (200.degree.-250.degree. C.), is prepared by melt extrusion through a die characterized by a hole density comprised between 10 and 150 holes/cm.sup.2 and provided with a cooling system of the emerging yarn of high efficiency and uniformity. The multifilament yarn can be subsequently drawn to obtain a fiber with even further improved tensile strength and modulus.
