Complications of Silicone Elastomer Prostheses
JAMA: The Journal of the American Medical Association, 1977To the Editor.— The report by Christie et al apparently correctly notes that silicone elastomer prostheses may produce foreign body reaction in a regional lymph node and synovitis. However, these mild inflammatory reactions have not been placed in proper clinical perspective. The authors correctly state, "Thousands of silicone elastomer...

Fatigue-resistant silicone elastomer formulations
Journal of Applied Polymer Science, 1998Fatigue-resistant elastomers have been prepared using various metal oxides as fillers in poly(dimethylsiloxane) (PDMS)-based elastomers. The judicious choice of inorganic fillers produced elastomers that were stable under cyclic testing at elevated temperatures.

Electrorheology of filled silicone elastomers
Journal of Rheology, 2001Electrorheological (ER) silicone elastomers containing particles based on silica (SiO2) and titania minerals (BaTiO3, Ba2Ti9O20, and BaTiO3/CaZrO3) were prepared and characterized. An electrical field was applied to align the particles during the cure of the silicone prepolymer.

Oxidation of Silicone Elastomer Finger Joints
The Journal of Hand Surgery, 2007We analyzed the oxygen content of 19 retrieved implants and 6 packaged implants to further understand the mechanism of degradation of silicone elastomer finger joints while in vivo.Nineteen Swanson (Wright Medical Technology, Arlington, TN) silicone elastomer finger joints were retrieved at revision surgery at an average of 7 years of use. Six packaged

Softness Evaluation of Silicone Elastomers
Chemistry Letters, 2011Abstract We evaluated the softness of various silicone elastomers installed on a tactile evaluation system. The softness of the elastomers was reflected by the vertical force when subjects pushed the elastomers with their fingers. The moving behavior depended on the elastic properties of the contacted objects; namely, a pushing pattern ...

Self-lubricating silicone elastomer biomaterials
Journal of Materials Chemistry, 2003Silicone has a relatively high coefficient of friction and silicone medical devices therefore lack inherent lubricity, leading to pain on device insertion and potential tissue trauma. In this study, higher molecular weight tetra(alkoxy)silanes, particularly tetra(oleyloxy)silane, have been used as crosslinkers in the condensation cure of a hydroxy end ...

Dynamic Analysis of Silicone Elastomers
Materials Science Forum, 2005The silicone elastomers offer in our days new perspective for the construction in the precision engineering and in the medicine because of their special mechanical, electrical, optical and chemical properties. Since the essential material parameters like storage modulus and loss modulus depend on temperature and frequency explicit it is important for ...

History of Silicone Elastomers
1986In a little more than 40 years silicone elastomers have emerged from laboratory curiosities to a broad family of synthetic, largely inorganic, materials useful in a wide variety of applications. Key discoveries in the development of silicone elastomer technology, including monomer synthesis and polymerization, crosslinking and reinforcement of the ...

DEVELOPMENT OF FLUORO-SILICONE ELASTOMERS
1955Abstract : The preparation of a homopolymer from 3,3,3-trifluoro-propylmethyldichlorosilane has been accomplished on a small scale. Experimental conditions have been studied for the re action of trichlorosilane and methyldichlorosilane with olefins. For hydrocarbon olefins, the best yield of addition product was obtained at 2500 C without a peroxide ...
