Patent ID: 7250127

Claim:
A pelletized organopolysiloxane material comprising a uniform dispersion of (A) at least one polyorganosiloxane composed of units of the formula I: R r SiO (4−r/2) (I), where R independently of one another, are hydrogen, or optionally substituted hydrocarbon radicals, and r is 0, 1, 2 or 3, with the proviso that the average numerical value of r is in the range from 1.9 to 2.1, (B) from 1 to 200 parts by weight, based on 100 parts by weight of the polyorganosiloxane (A), of a reinforcing or non-reinforcing filler, or of a mixture of reinforcing or non-reinforcing fillers, and (C) from 0.01 to 20 parts by weight, based on 100 parts by weight of the polyorganosiloxane (A) of at least one boric acid-containing additive for producing pellets, said additive consisting essentially of boric acid, water, and optionally fatty acid salt, the boric acid having been supplied to the composition dissolved in water, the water optionally removed prior to pelletizing, and whose pellet size is from 1 to 100 mm.
