Abstract
Solventless, thermoplastic silicone pellets are prepared blending silicone resins (A) of the MQ-type and with predominantly linear silicone fluids (B), such as polydimethylsiloxane liquids and gums, to substantially homogeneity. The blends are heated to a predetermined compression-forming temperature, compression-formed to a densified mass and shaped into a pellet form. The composition of the pellets is balanced such that the pellets exhibit plastic flow at the predetermined compression-forming temperature and resist agglomeration at temperatures at or below a predetermined maximum storage temperature.
