摘要： A material susceptible to dielectric heating has a base polymeric thermoplastic material (1) and a dielectric heating susceptor (2, 3) which increases susceptibility to heating by irradiation with electromagnetic, for example RF or microwave, radiation. The dielectric heating susceptor has a polymeric material (2) such as PVDF which is different from the base polymeric material and has a higher dielectric loss factor than the base polymeric material. The dielectric heating susceptor also comprises electrically polarisable entities such as carbon black dispersed within the base polymeric material without forming a conductive network. The two susceptor materials in combination with the base polymer are particularly effective together at improving susceptibility to electromagnetic radiation heating of the whole material.
