Effectiveness factors of fine particle catalysts embedded in silicone rubber.

'Silicone rubber' lenses in aphakia.

Tesicon, one of the commercially available 'silicone rubber' lenses, was used in the correction of aphakic patients. In 74% of cases the lenses were considered successful for a daily wear regimen by the patient. Furthermore, a small number of patients could wear this lens without interruption for 3 to 6 days at a time. Despite this good acceptance by patients, corneal problems (mainly staining)...

Physical properties of silicone rubber.

2 Mechanical engineer, USAMBRL. 3 Major, Army Medical Specialist Corps, USAMBRL. ROOM-TEMPERATURE-VULCANIZING (RTV) silicone rubber is a versatile material and easy to handle. The ingredients from which it is formed are thick liquids that vulcanize at room temperature within a short period of time after the catalyst is added. Depending upon the relative amounts of solid and foam ingredients, th...

Fungal colonisation in digital silicone rubber prostheses.

The fungal discolouration of silicone rubber prostheses is reported in four cases. In two of the cases, the discolouration was caused by the fungus Candida tropicalis. In the other two cases, two different fungal organisms, namely Trichoderma sp. and Scedosporium prolificans were incriminated. The non-porous silicone rubber layers create an enclosed environment in the suction cup of the prosthe...

Controlled release of testosterone using silicone rubber.

Electrospinning of commercially available medical silicone rubber

Polyelectrolyte multilayer (PEM) films, established using the layer-by-layer (LbL) technique, are attractive for controlled drug delivery in order to improve tissue regeneration. For instance, the LbL-deposition provides the possibility to incorporate biomolecules via electrostatic interactions for drug delivery, which might be moreover combined with a stable biofunctionalization via covalent b...
