A composition of enhanced radio frequency sensitivity and a method for providing enhanced radio frequency sensitivity to a composition in which a substance suitable for enhancement of radio frequency sensitivity is admixed with a radio frequency sensitizing amount of an inorganic radio frequency sensitizer treated essentially to remove absorbed water and/or other volatiles with the radio frequency sensitizer chosen from among zinc oxide (American Process), bentonite clay, and crystalline or amorphous alkali or alkaline earth metal aluminosilicate. A process for molding using these compositions and the molded product. The composition, method for enhancing radio frequency sensitivity, process for molding and molded product with a polymeric substance, particularly ultra high molecular weight polyethylene, as the substance suitable for enhancement of radio frequency sensitivity.
A method for molding wherein a substance suitable for radio frequency enhancement is treated by the method comprising admixing with said substance suitable for radio frequency enhancement a radio frequency sensitizing amount of zinc oxide (American process) inorganic radio frequency sensitizer treated essentially to remove absorbed an/or other volatiles and then subjected to radio frequency energy in a molding process.
A method for molding wherein a substance suitable for radio frequency enhancement is treated by the method comprising admixing with said substance suitable for radio frequency enhancement a radio frequency sensitizing amount of bentonite clay inorganic radio frequency sensitizer treated essentially to remove absorbed water and/or other volatiles and then subjected to radio frequency energy in a molding process.
A method of molding wherein a composition comprising a substance suitable for enhancement of radio frequency sensitivity and a radio frequency sensitizing amount of zinc oxide (American process) inorganic radio frequency sensitizer treated essentially to remove absorbed water and/or other volatiles is subjected to radio frequency energy in a molding process.
A method for molding wherein a composition comprising a substance suitable for enhancement of radio frequency sensitivity and a radio frequency sensitizing amount of bentonite clay inorganic radio frequency sensitizer treated essentially to remove absorbed water and/or other volatiles is subjected to radio frequency energy in a molding process.
