Abstract
A method for manufacturing a liquid silicone rubber composition including a preparation step, a mixing step, an introduction step, and a curing step. The preparation step includes providing at least a first gel and a second gel. The mixing step includes mixing the first gel and the second gel to form a mixed gel. The introduction step includes introducing the mixed gel into a mold. The curing step includes heating up the mold to cure the mixed gel to form a liquid silicone rubber composition.
Claims15
A liquid silicone rubber composition, comprising:
- vinyl-terminated polydimethylsiloxane (PDMS) accounting for 39 wt % to 62.5 wt % of said liquid silicone rubber composition;
- silicon dioxide accounting for 25 wt % to 30 wt % of said liquid silicone rubber composition;
- polymethylhydrogensiloxane (PMHS) accounting for 4.5 wt % to 17.5 wt % of said liquid silicone rubber composition;
- and
- a catalyst accounting for 0.1 wt % to 1 wt % of said liquid silicone rubber composition.
A method for manufacturing a liquid silicone rubber composition, comprising:
- performing a preparation step to at least provide a first gel and a second gel, wherein said first gel comprises vinyl-terminated polydimethylsiloxane (PDMS) accounting for 30 wt % to 45 wt % of said first gel, silicon dioxide accounting for 25 wt % to 30 wt % of said first gel, and polymethylhydrogensiloxane accounting for 5 wt % to 25 wt % of said first gel, said second gel comprises vinyl-terminated polydimethylsiloxane accounting for 60 wt % to 70 wt % of said second gel, silicon dioxide accounting for 25 wt % to 30 wt % of said second gel and a catalyst accounting for 0.1 wt % to 1 wt % of said second gel;
- performing a mixing step to mix said first gel and said second gel to form a mixed gel;
- performing an introduction step to introduce said mixed gel into a mold;
- and
- performing a curing step to heat up said mold to cure said mixed gel to form said liquid silicone rubber composition.
