  • Publication number: 20100147555
    Abstract: A non-woven sheet contains sheath/core polymer fibers with the polymer in the sheath having a melting point at least 15 degrees centigrade higher than the melting point of the polymer of the core. Preferably, the polymer of the sheath is polyphenylenesulfide and the polymer of the core is polyethyleneterephthlate. The nonwoven sheet can be used with a film to make a composite laminate suitable for use in electrical insulation.
