Absorption of silicone fluid in a silicone elastomer
Journal of Materials Science, 1991Measurements have been made of the absorption properties of a silicone fluid in a silicone elastomer, Aircast 3700, at temperatures between 0 and 150 °C. It was found that the diffusivity could be described by Arrhenius' law. The saturation fluid content was 20% at 0 °C, decreasing to 17% at 120 °C.

Highly active, lipase silicone elastomers
Biomaterials, 2005Lipase Candida rugosa was entrapped in silicone rubber via condensation-cure room temperature vulcanization of silanol-terminated poly(dimethylsiloxane) with tetraethyl orthosilicate as a crosslinker, to give a highly active silicone-enzyme elastomer.

Silicone Elastomer Plombage for Severe Hemoptysis
Archives of Surgery, 1973A 58-year-old man suffered massive, life-threatening hemoptysis secondary to cavitary tuberculosis. Silicone elastomer augmentation mammoplasty prostheses were inserted for cavitary collapse and as an urgent measure to control hemoptysis, with use of the well-known technique of extracostal subperiosteal plombage.

Silicone elastomers for reduced protein adsorption
Biomaterials, 2004Monofunctional poly(ethylene oxide) polymers of molecular weight (MW) 350, 750, and 2000, respectively, were modified with Si(OEt)3 groups. These polymers underwent classic condensation cure with hydroxy-terminated silicone polymers and Si(OEt)4 to give composites with poly(ethylene oxide) (PEO) rich surfaces under aqueous conditions, as shown by ...

Thyroplasty Using A Silicone Elastomer Implant
Otolaryngologic Clinics of North America, 1995Silicone has been used in a variety of forms as a replacement for soft tissue for more than three decades in the United States. The safety of this practice has come under scrutiny recently as our knowledge of the local, systemic, and immune effects of silicone has expanded. Contrary to what was once thought, silicone is not biologically inert. Silicone

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...

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 ...

Silicone Elastomer Implantation Cyclodialysis
Archives of Ophthalmology, 1973Five eyes with severe secondary angleclosure glaucoma were operated upon using the silicone elastomer (Silastic) implantation cyclodialysis procedure. It was not possible to thereby significantly reduce the intraocular pressure except for one eye, which also underwent a cyclodiathermy.

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 ...
