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...
متن کاملModifying the setting rate of an addition-type silicone impression material.
Two methods for controlling the working time of an addition-type silicone impression material are presented. The progress of the polymerization reaction of this modified system was studied using viscosity and a new "compression set" technique. The physical properties are presented and compared to those typical of condensation silicones, and a method of clinical use is suggested.
متن کاملMicrobiological deterioration of vulcanized rubber.
Data are presented which show that the constitution of the recovery medium exerts an appreciable effect on the apparent thermal resistance of spores of Putrefactive Anaerobe 3679. The routine use of a simple yeast extract-starch medium (YES) as a recovery medium in thermal resistance studies on this organism is recommended. In addition to giving thermal resistance values comparable to those obt...
متن کاملVulcanized rubber foot for lower limb amputees.
A prosthetic workshop was started some years ago at the S.M.S. Medical College Hospital , Jaipur , t o meet the growing demands of the local populat ion. Unlike the premier limb-fitting centres in India which still cater for the more affluent sections of society, it was decided that this centre would also look after the p o o r rural amputees . I t soon became apparent that a disturbing number ...
متن کاملA build-up impression technique for the edentulous mandible using various viscosities of silicone impression material.
most difficult impression to make during complete denture construction. Ill-fitting lower complete dentures are often a source of discomfort for patients. While implant retention helps to achieve vertical stability, unless a completely implant-supported denture is being made, the denture must have good tissue contact and correct anatomical extension. An impression technique is required that cap...
