Maxillofacial Silicone Elastomers in Dentistry
2020Maxillofacial prostheses are used for patients with deformities in the maxillofacial area induced by cancer, trauma or congenital defects. Different types of polymers are used in the manufacture of maxillofacial prosthesis. However, silicone elastomers are the polymers most commonly used in the maxillofacial prosthodontics because of their acceptable ...

DEVELOPMENT OF FLUORO-SILICONE ELASTOMERS
1955Abstract : The preparation of a homopolymer from 3,3,3-trifluoro-propylmethyldichlorosilane has been accomplished on a small scale. Experimental conditions have been studied for the re action of trichlorosilane and methyldichlorosilane with olefins. For hydrocarbon olefins, the best yield of addition product was obtained at 2500 C without a peroxide ...

The Adjuvant Effect of Silicone Gel and Silicone Elastomer Particles in Rats
1996This study examines the adjuvant properties of silicone oil, silicone gel and silicone elastomer using a foreign antigen, bovine serum albumin (BSA). Seventy male Harlan Sprague-Dawley rats, approximately 250 grams each, were divided into 7 groups: A- incomplete Freund's adjuvant (IFA) with BSA; B- silicone oil with BSA; C- IFA/silicone oil with BSA; D-

Compression Set of Silicone Elastomers
International Polymer Science and Technology, 2009Compression set is one of the most important properties of rubber, particularly for sealing applications. Nevertheless, this key characteristic is frequently disregarded or misinterpreted when it comes to material selection. Compression set and the method of determining this material property are described by reference to silicone elastomers. Critical

Preparation and Properties of Silicone Elastomers
2000Silicones have been commercially available since the 1940’s and the most dominant member of this class of synthetic polymers is poly(dimethylsiloxane), (PDMS) -[(CH3)2SiO] y —. The polysiloxane or silicone industry may be conveniently grouped into products based upon fluids (which may or may not contain functional groups), cross-linked elastomers and ...

DEVELOPMENT OF FLUORO-SILICONE ELASTOMERS
1958Abstract : Some promising fluoroalkylsilane monomers and polymers have been prepared for use as high temperature and aircraft fuel resistant elastomeric materials. In addition to the halosilanes previously synthesized, the following new silanes were prepared: Bis(trifluoropropyl)dichlorosilane; (Chlorohexafluorocyclobutylethyl)-methyldichiorosilane; (2-

Catalysis of Silicone Elastomer Adhesion
1975Room-temperature curing silicone elastomers will adhere well to unprimed, unanodized aluminum and steel if they contain alkoxysilyl groups (at least initially) and if the substrate has been brought into contact with certain anions either before or during cure.
