Silicone Biomaterials: History and Chemistry

Stain removal from a silicone maxillofacial elastomer.

In this study, environmental stains were removed from maxillofacial elastomers by solvent extraction. Silastic 44210, an RTV silicone with proven color and physical property stability, was stained with lipstick, disclosing solution, and methylene blue. These stains were then removed by solvent extraction with each of four chemically dissimilar solvents, namely: toluene, benzene, 1,1,1-trichloro...

Reiterated tension testing of silicone elastomer

A peristaltically actuated device, PADeMIS, composed of silicone rubber (SR) is under development for use in minimally invasive surgery. During locomotion, the device will be subject to a few thousand load changes involving varying, sometimes high, strains. The design is being optimised by finite element analysis, for which a constitutive law for the mechanical behaviour of silicone rubber is r...

Studies on Surface Modification of Silicone Biomaterials

This paper presents our studies on surface modification of silicone elastomer by collagen grafting/coating and electron beam irradiation. Two types of collagen hydrolysates with different molecular weights were obtained and characterized, which were used in experiments. Both silicone elastomer crosslinking and collagen grafting on the surface of silicone elastomer were achieved by electron beam...
