Adding silica particles having specified collective characteristics to a fluororubber formulation enhances direct adhesion between the fluororubber formulation and a copolymer upon curing. Specifically, as measured before being mixed into the fluororubber formulation, the silica particles have an average value of the product “(particle size)×(circularity)” that is 17.5 nm or higher and 500 μm or lower. The silica particles may also have an average particle size of between 25.0 nm inclusive and 500 μm inclusive, and an average circularity of 0.80 or higher. Alternatively, as measured after being incorporated into the fluororubber formulation and then cured, the silica particles have an apparent average value of the product “(particle size)×(circularity)” that is 32.0 nm or higher and 500 μm or lower. The silica particles may also have an apparent average particle size of between 40.0 nm inclusive and 500 μm inclusive as measured after being incorporated into the fluororubber formulation and then cured.

A microwave heatable composite material that comprises: a heat resistant moldable base material; a microwave heatable material dispersed in the heat resistant moldable base material; and a phase change material dispersed in the heat resistant moldable base material. The mixture of the microwave heatable material, heat resistant moldable base material, and phase change material provide a basic or core microwave heatable article layer to which one or more additional controlled heat releasing and/or heat transfer blocking layers can be combined to enhance and optimize heat therapy. In addition, the microwave heatable articles of the present invention can be used for cold therapy by lowering their temperatures in a freezer of similar cold environment.
