ABSTRACT:
The invention comprises processes for the production of useful fluid or grease from curable silicone compositions or silicone rubbers, preferably reclaimed or scrap silicone rubber. The processes involve the application of energy in such a manner that a un-curable silicone grease or liquid that contains essentially all of the original material is produced from curable silicone compositions and grease or liquid is produced from silicone rubbers. Suitable energy forms include thermal and mechanical. The fluid or grease produced by the processes are useful as raw materials for the manufacture of silicone products such as: antifoam compounds (defoamers), greases, conformal coatings or rubbers. The materials produced by these processes were unexpectedly found to have exceptional antifoam properties without requiring the addition of other materials or further processing. A second unexpected finding is that finely ground silicone rubber possesses antifoam properties and that grinding and extraction techniques can produce a silicone fluid with significant utility in foam suppression. Foam suppression is also achieved through the direct addition of ground silicone rubber to certain foaming systems. A process for controlling foam that involves adding silicone rubber that has been softened by ultrasonic means to a foaming system is also revealed.
