Abstract
A lightweight silicone ear molding putty composition is disclosed for chronic ear patients and myringotomy children to protect ears which includes a mixture comprising of silicone hydroxy functional fluid, crosslinker, and tints as well as a number of additives for adjusting the properties of the mixture and further including an admixture of hollow thermoplastic microspheres containing microcrystalline silica embedded onto the sphere combined with a 5 micron diatomic functional filler. The final composition cures in five minutes to a floating ear plug. Utilizing a mixture of thermoplastic microspheres of 10 to 80 microns and silicone hydroxy fluid ranging from 18,000 to 20,000 centipoise said composition is cured at room temperature, hand mixed, moldable, and syringed into the ear to make an ear plug or mold which has superior properties over prior art ear plugs.
