Dynamic shear modulus G' was measured throughout the volume of three nonvariant silicone rubber poppets which were recovered from aortic prosthetic heart valves that had been implanted for 4 days, 52 days, and 8 years. Similar measurements were obtained for two unused silicone rubber poppets. ...

With the addition of 2 phr of MWCNTs to the rubber matrix, the Young’s modulus increased by 272% and reached as high as 706% at 8 phr, whereas the modulus increased only 125% for CB specimens at 10 phr, which is likely due to the higher surface area of the MWCNTs and polymer-...
3. It has strong anti-displacement ability. For the normal expansion and shear deformation of the curtain wall, this product can maintain the same performance and play an effective sealing role. 4.Excellent weathering resistance, aging resistance, UV resistanc...
Specifically, both highly stretchable silicone elastomers (maximum strain of 2800%) and extremely soft silicone elastomers (lowest shear modulus of 1.2 kPa) are prepared by creating highly entangled elastomers and bottle-brush elastomers from commercial precursor polymers, respectively....
additives and modifiers in the present curable compositions, for example, a silicone oil in order to improve toner releasability, pigments, heat stabilizers, flame retardants, plasticizers, and organopolysiloxanes having one alkenyl radical in each molecule to lower the modulus of the cured rubber. ...
2 or 3, q is 1 or 2, x is greater than or equal to 6, and y ranges from zero to 10; and said organosilicon composition (A) and said silicone rubber (B) being present in relative quantities such that said rubber-modified silicone resin has a Young's modulus of at least 6.9×108...
