5 mm particles of an active ingredient 30 can potentially be formed of any material for example particles of an active ingredient 30 may absorb or adsorb fluids or gases furthermore particles of an active ingredient 30 may be used to release fluids or gases held therein for example to deliver fluids such as medicaments materials such as iodinated resin activated carbon activated alumina aluminum powders nickel powders alumina silicates ferromagnetic materials ion exchange resins manganese or iron oxides zeolites glass beads ceramics diatomaceous earth and cellulosic materials can also be used as particles of an active ingredient 30 in addition particles of an active ingredient 30 may also be polymeric materials such as sap the cross sectional size of particles of an active ingredient 30 is preferably within a range of about 5 microns to about 5000 microns materials forming binder particles 40 may potentially include any material known in the art in particular thermoplastic and thermoset materials are useful for the practice of the present invention for example binder particles 40 may be polyethers polyolefins polyvinyls polyvinyl esters polyvinyl ethers ethylene vinyl acetate copolymers or a mixture thereof also suitable binder particles may be produced from particulate thermoset resins known in the art such as phenol formaldehyde.
