History of Silicone Elastomers

1986
In a little more than 40 years silicone elastomers have emerged from laboratory curiosities to a broad family of synthetic, largely inorganic, materials useful in a wide variety of applications. Key discoveries in the development of silicone elastomer technology, including monomer synthesis and polymerization, crosslinking and reinforcement of the ...

Porosity and color of maxillofacial silicone elastomer.

Journal of prosthodontics : official journal of the American College of Prosthodontists, 2011
Prosthesis color production and stability as a result of pore entrapment during mixing has not been investigated for maxillofacial silicone prostheses. The purpose of this study was to investigate pore numbers and percentages of a maxillofacial silicone elastomer mixed by two different techniques, using X-ray microfocus computerized tomography (Micro ...

Electrorheology of filled silicone elastomers

Journal of Rheology, 2001
Electrorheological (ER) silicone elastomers containing particles based on silica (SiO2) and titania minerals (BaTiO3, Ba2Ti9O20, and BaTiO3/CaZrO3) were prepared and characterized. An electrical field was applied to align the particles during the cure of the silicone prepolymer.

Maxillofacial Silicone Elastomers in Dentistry

2020
Maxillofacial 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 ...

Fillers for polysiloxane (“silicone”) elastomers

Progress in Polymer Science, 2010
Abstract Polysiloxane elastomers having the structure [SiRR′–O–] x have long been used as high-performance materials, but only when reinforced with relatively large amounts of filler. This has generally been silica that had been prepared either in the gas phase or in aqueous solution. The present review describes some alternative fillers that have

DEVELOPMENT OF FLUORO-SILICONE ELASTOMERS

1955
Abstract : 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

1996
This 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, 2009
Compression 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
