Abstract

Mould blocks made of low dielectric loss insulating resins for moulding a high loss material between high frequency electrodes, where the temps of the cavity surfaces are increased by loading the insulating resin with a high loss filler, pref. using between 10-30% wt. filler w.r.t the matrix, pref. of metal flake, esp. Al. Esp. suitable for heating e.g. plastisols in cavities which vary in depth by about 10:1 e.g. a shoe sole with an integral heel, with or without a fabric lining, so as to gel the thin sections before thermal degradation occurs at the heart of the thick sections.
