ABSTRACT:
An improved electrical insulation tape is formed from a sheet of fiberglass cloth having a layer of thermoplastic resin bonded thereto. The thermoplastic resin layer is applied to the fiberglass sheet by melting the resin while contacting the fiberglass, and then the composite is cooled to bond the two components together. The composite sheet is then slit into tapes with substantially no unraveling of the fiberglass component at the slit edges of the tapes. The resultant tapes are easily wrapped on, and adhered to, conductors, such as magnet wire, or the like, by remelting and resolidifying the thermoplastic layer. The tape possesses excellent dielectric properties and heat dissipation properties. Alternatively, the fiberglass sheet may be impregnated with the melted thermoplastic component whereby a composite, rather than a relatively definitive two layer laminate, is formed.
