Abstract
An electrical circuit board fluoropolymer substrate and method of manufacture thereof, comprising a fluoropolymer matrix that includes a mixture of a granular first fluoropolymer resin and a dispersion second fluoropolymer resin. Preferably, the first and second fluoropolymer is polytetrafluoroethylene (PTFE). This mixture is suitable for forming unfilled or filled casting compositions to form thick films, or for dip-coating glass webs.
