Since the insulators of transmission lines are exposed to different environmental conditions, it is important task to study insulators performance under different conditions. In this paper, silicone rubber insulators performance under different environmental conditions including rainy, icy, salt and cement are proposed and exactly is studied. Electric fields (E-fields) and voltage distributions...

The uniaxial compressive responses of silicone rubber (B452 and Sil8800) and pig skin have been measured over a wide range of strain rates (0.004–4000 s ). The uniaxial tensile response of the silicone rubbers was also measured at low strain rates. The high strain rate compression tests were performed using a split-Hopkinson pressure bar made from AZM magnesium alloy. High gain semi-conductor s...

One in eight American women develops breast cancer. Of the many patients requiring mastectomy yearly as a consequence, most elect some form of breast reconstruction. Since 2006, only silicone breast implants have been approved by the FDA for the public use. Unfortunately, over one-third of women with these implants experience complications as a result of tissue-material biocompatibility issues,...

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...

modification of the mechanical properties of silicone rubber were considered for drug delivery systems by using high-energy electron beam (e-beam). in this research work, two different medical grades of silicone rubbers were used to prepare matrices containing 10wt% progesterone with 2 mm thickness and irradiated with e-beam at dose range of 25 up to 200 kgy. then, the mechanical properties as ...

A common complaint among patients with burns is their inability to grasp items while wearing compression gloves. Recent technological innovations permit the addition of grip-enhancing material to garment fabric. The purpose of this case series was to describe the course of development of compression gloves with enhanced grip modifications. Five different types of grip modifications were made du...

A method is described for coating silicone rubber-encapsulated implant devices with an outer layer of silicone rubber impregnated with a mixture of gentamicin sulphate and diethanolamine fusidate. A coating of this sort provides bactericidal activity lasting for a few days in the film of fluid surrounding such an implant. When used for coating our implants, the retrospective rate of implant inf...

The effect of lateral pressure on the wavelength response characteristics of a fiber Bragg grating embedded in a cylindrical package of silicone rubber has been investigated in this report. Due to high Poisson’s ratio (0.48) and low stiffness of silicone rubber, force applied in one direction will be efficiently transferred to the perpendicular direction also. A wavelength shift of more than 1 ...

Five different water passive samplers were calibrated under laboratory conditions for measurement of 124 legacy and current used pesticides. This study provides a protocol for the passive sampler preparation, calibration, extraction method and instrumental analysis. Sampling rates (RS) and passive sampler-water partition coefficients (KPW) were calculated for silicone rubber, polar organic chem...

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)...
