COMPOUNDING FILLED SILICONE COMPOSITIONS |
摘要 |
High levels of silica, processing fluid and high molecular weight silicone polymer are compounded into a homogeneous silica filled composition without forming a preconcentrate of fumed silica and polymer. A fumed silica is fed into a unitary continuous compounding apparatus at a first location prior to addition of the silicone polymer. The fumed silica is then compounded with the silicone polymer, which is fed into the compounding apparatus at a location down-stream in the compounding apparatus from the first location. The compounding apparatus can be a co-rotating, intermeshing double screw extruder. |
