Various materials have been used to replace lost anatomic parts and for the repair of deformities. In 1953 Scales 1 outlined the properties of an ideal soft-tissue substitute. These properties are as follows: (1) not physically modified by tissue fluid, (2) chemically inert, (3) no inflammatory reaction, (4) nonallergenic, (5) noncarcinogenic, (6 ...

New silicone rubbers, 1. Hydrophilic silicone rubbers
Die Angewandte Makromolekulare Chemie, 1993Abstract3‐O‐Allylglucose (1), allylglucoside (2) and sucrose‐allylether‐mixtures (3), respectively, protected by trimethylsilyl (TMS)‐groups have been used as unsaturated components in crosslinking of commercially available RTV silicone components. The resulting hydrophobic silicone rubbers were converted into hydrophilic types with covalently bonded ...

New silicone rubbers, 2. Biocompatible silicone rubbers
Die Angewandte Makromolekulare Chemie, 1993AbstractBiokompatible silicone rubbers have been prepared using fillers based on two types of modified amorphous silica: (i) silica containing covalently bonded reactive H‐Si‐groups (1) obtained by reaction of silica with methyldichlorosilane, and (ii) silica with covalently immobilized antithrombogenic agent (5), prepared by reaction of 1 with ...

Silicone Rubber Suction Tubing
JAMA: The Journal of the American Medical Association, 1969To the Editor:— Most operating room suction tubing is either natural rubber (amber, gum, latex) or a natural-synthetic combination (as red rubber). These products soften, darken, and become gummy after 50 to 75 steam autoclavings and must be discarded.

Silicone rubber and natural rubber as biomaterials
Medical & Biological Engineering & Computing, 1980The roles of silicone rubber and natural rubber as biomaterials are contrasted, with silicone rubber being widely used and natural rubber having, as yet, found limited application. Relevant properties of both elastomers are described, applications are discussed and possible future developments are considered.

Rubber Chemistry and Technology, 1983
Abstract The method of preparation of elastic permanent magnets of silicone rubber is described, and the values of the basic magnetic properties of these rubbers, i.e., the coercive force, the remanent induction, and the maximum energy product, are given.

Modeling processing of silicone rubber: Liquid versus hard silicone rubbers
Journal of Applied Polymer Science, 2010AbstractThe processing of hard and liquid silicone rubbers (LSR) are compared by means of modeling and simulation. The curing process for both, hard and liquid silicone, are modeled using the auto‐catalytic Kamal‐Sourour model and a nonlinear regression method is used to find the kinetic parameters.
