P & P Technology Silver Aluminum Loaded Silicone EC-J a fluorosilicone elastomer with a silver / copperconductive filler.

P & P Technology Carbon Loaded Silicone EC-C which when properly catalyzed can be considered for applications requiring conductivity such as EMI gaskets, conductive sheaths for ignition cable core, electronic keyboard contacts, etc.

P & P Technology Silver Copper Loaded Silicone EC-H is a silicone elastomer with Silver conductivefiller. It is tan in color.

Silicraft 111® is the first silicone RTV projectable 1/1 mixture without phase air bubble removal.

StarPCS™ SBMC-601 is a discontinuous carbon fiber reinforced molding compound containing carbon fiber, a vinyl substituted polysiloxane resin, and refractory particulate. SBMC-601 cures at temperatures between 180-250o C and functions as a high temperature carbon fiber reinforced structure with a silicon oxycarbide ceramic. Curing produces a green fiber reinforced composite material. Further processing to 850o C (minimum) in inert gas results in an amorphous silicon oxycarbide matrix ceramic composite that can be used as a pre-form for use with different infiltration polymers or materials. Ideal infiltration polymers include Polyramic® SPR-688 or SPR-212 based slurries (SL-227, SL-480), and other Starfire® Systems polysiloxane products.

StarPCS™ SBMC-843 is a discontinuous carbon fiber reinforced molding compound containing carbon fiber, a Starfire proprietary polysiloxane resin, and refractory particulate. SBMC-843 contains a Polyramic® thermosetting resin which cures at temperatures between 200-310°C, and functions as a high temperature carbon fiber reinforced structure with a silicon oxycarbide ceramic matrix. Compression mold curing produces a green fiber reinforced polymer matrix composite (PMC) material. Further processing to 850°C minimum in inert environment results in an amorphous silicon oxycarbide ceramic matrix composite (CMC) to be used with different infiltration polymers or materials. Ideal infiltration polymers include Polyramic® SPR-212, SPR-212 based slurries (SL-227, SL-480), and other Starfire® polysiloxane products.

Tufnol Grade 10G/50 is a laminated plastics material made from woven glass fabric, bonded with silicone resin. It is a rigid sheet material with good resistance to high temperatures and very good electrical insulation properties, especially in applications involving very high frequencies. Note, however, that silicone bonded laminates have mechanical strength properties somewhat lower than some other glass fabric laminates.
