  • ENVIRONMENT Dow Corning undertakes waste-to-energy project
    Chemical & Engineering News, 2007
    Co-Authors: Marc Reisch
    Abstract:

    Silicones maker Dow Corning has started a $50 million project to outfit its Midland, Mich., plant with equipment intended to reduce carbon dioxide emissions by 20%, cut other emissions by 75%, recycle hydrochloric acid, and lower annual natural gas consumption by 400 billion Btu—enough to heat more than 3,500 homes during the winter. The project, set for completion in mid-2008, will depend on a plasma-based waste-processing system, the first of its kind to be installed in the U.S. Integrated Environmental Technologies (IET) will own the system, which will handle more than 6,600 tons of waste per year. Dow Corning begins the silicone-manufacturing process with chlorosilanes. It will feed chlorinated organic waste generated during chlorosilane production to IET’s plasma-enhanced melter. The plasma system will separate the wastes into organic and chlorine streams. Dow Corning will pay IET to manage the waste streams. The system will then convert the organic stream into a synthetic gas, which ...

  • OUT OF THE WOODS
    Chemical & Engineering News, 2004
    Co-Authors: Marc Reisch
    Abstract:

    BARRING LAST MINUTE COMplications, Dow Corning will end a nine-year stint under court supervision when it emerges from bankruptcy reorganization on June 1. Stephanie A. Burns, Dow Coming's CEO, says she credits the focus and resolve of employees on servicing customers while the lawyers handled bankruptcy details for getting Dow Corning to this point. However, trimming employment to improve the firm's financial performance will be among the first orders of business. A Dow Corning spokeswoman says about 250 positions—nearly 3% of the workforce—are slated to go by year's end. A merger of several business units last year left redundancies, she adds. Judge Denise Page Hood of U.S. District Court for the Eastern District of Michigan set the date to end Dow Coming's ordeal just two weeks after an attorney representing 48 Nevada women dropped his appeal of the firm's $3.2 billion settlement with silicone gel breast implant recipients. Some 170,000 ...

  • Dow Corning Closer To Emerging From Bankruptcy
    Chemical & Engineering News Archive, 2002
    Co-Authors: Marc Reisch
    Abstract:

    A federal district court judge has affirmed her two-year old ruling that women with silicone gel breast implants cannot recover damages from Dow Chemical and Corning, parents of implant maker Dow Corning. The ruling means Dow Corning could emerge from bankruptcy in 2003. The three companies consider the release key to a 1998 plan worked out between implant recipients and the silicones maker. In 1999, a bankruptcy court judge approved the plan but excluded the no-sue provision. Subsequent appeals have kept Dow Corning under supervision, thus delaying payments of $3.2 billion to claimants and $1.3 billion to creditors. The 6th U.S. Circuit Court of Appeals in Cincinnati still has to approve the district court judge's ruling. And the appeals court is likely to consider objections from plaintiffs who insist they should be allowed to recover damages from Dow Coming's parents. According to documents filed with the Securities & Exchange Commission, ...

  • Dow Corning: BACK TO BUSINESS?: If claimants and judge approve plan now in the mail, Dow Corning could soon resolve its bankruptcy status
    Chemical & Engineering News, 1999
    Co-Authors: Marc Reisch
    Abstract:

    It has been a long and slippery road for Dow Corning, at one time manufacturer of more than half of all silicone gel breast implants made in the U.S. The silicone maker sought protection nearly four years ago under Chapter 11 of the bankruptcy reorganization codes as the potential cost of implant recipient claims skyrocketed. Since then, Dow Corning has tried to extricate itself from a legacy of accusations and recriminations over the alleged health effects of silicone gel breast implants. The end of that road may now be in sight as the company and its principal antagonists claim exhaustion and seek resolution. Roughly 700,000 copies of a court document are now in the mail describing a reorganization plan that implant claimants and Dow Corning put together. The mailing consists of a 265-page disclosure statement and supporting documents. Recipients of the mailing include 570,000 claimants eligible to vote on the plan and other interested parties, ...

  • Recovery of Valuable Chlorosilane Intermediates by a Novel Waste Conversion Process
    2002
    Co-Authors: J. Ashley Brinson
    Abstract:

    From 1994 to 2001, Dow Corning studied a waste recycling process to recover direct process residues (DPR) resulting from the production of silicone precursors. Over the course of eight years, Dow Corning constructed and operated a pilot plant, a small scale commercial plant, and a full scale plant. The process reacts DPR with hydrogen and chlorosilane monomers at high temperature and high pressure. The process converted 85% of the DPR to valuable chlorosilane monomers such as dimethyldichlorosilane and methyldichlorosilane. When feeding methyltrichlorosilane, the process converted 30% of the MeSiCl3 to other monomers. Alternate co-feed monomers were tested. By converting waste DPR to valuable intermediates, the technology significantly reduces waste from the basic silicones manufacturing process.

  • room temperature corcoran Dow Corning silicone plastination process
    Anatomia Histologia Embryologia, 2019
    Co-Authors: Dmitry Starchik, Robert W Henry
    Abstract:

    For 20 years, the cold temperature/S10/von Hagens' plastination technique was used to preserve biological specimens without challenge. It became the "gold standard" for preservation of beautiful, dry biological specimens. Near the end of the 21st century, a group from the University of Michigan and environs and Dow Corning™, USA, combined silicone ingredients, similar to the von Hagens' plastination products, however in a different sequence. The new polymer (Cor-tech) was combined with the cross-linker to design the "impregnation mix" which would invade the cellular structure of the specimen and yet was stable at room temperature. Later, curing would be by application of the catalyst onto the impregnated specimen. This unique sequencing of products would become the "Room temperature/Dow Corning™/Corcoran-Silicone plastination technique." The results of this room temperature technique provided similar plastinates, beautiful and practical for demonstration, containing no toxic chemical residues and forever preserved. As the name implies, impregnation of this silicone mix could be done at room temperature, without having to be kept cold. Both processes (cold and room temperature) required the same four basic steps for plastination. As well, both processes used similar basic polymers and additives to produce plastinates. However, they were combined in a different sequence. Cold temperature combines polymer and catalyst/chain extender, which is not stable and therefore must be kept colder than -15°C, while room temperature combines polymer with cross-linker which is stable, and likely forever.

  • Load Deflection of Dow Corning SE 1700 Face Centered Tetragonal Direct Ink Write Materials: Effect of Thickness and Filament Spacing
    2016
    Co-Authors: Ward Small, Mark A. Pearson, Tom R. Metz
    Abstract:

    Dow Corning SE 1700 (reinforced polydimethylsiloxane) porous structures were made by direct ink writing (DIW) in a face centered tetragonal (FCT) configuration. The filament diameter was 250 μm. Structures consisting of 4, 8, or 12 layers were fabricated with center-to-center filament spacing (“road width” (RW)) of 475, 500, 525, 550, or 575 μm. Three compressive load-unload cycles to 2000 kPa were performed on four separate areas of each sample; three samples of each thickness and filament spacing were tested. At a given strain during the third loading phase, stress varied inversely with porosity. At 10% strain, the stress was nearly independent of the number of layers (i.e., thickness). At higher strains (20- 40%), the stress was highest for the 4-layer structure; the 8- and 12-layer structures were nearly equivalent suggesting that the load deflection is independent of number of layers above 8 layers. Intra-and inter-sample variability of the load deflection response was higher for thinner and less porous structures.

  • Load Deflection of Dow Corning SE 1700 Simple Cubic Direct Ink Write Materials: Effect of Thickness and Filament Spacing
    2016
    Co-Authors: Ward Small, Mark A. Pearson, Tom R. Metz
    Abstract:

    Dow Corning SE 1700 (reinforced polydimethylsiloxane) porous structures were made by direct ink writing (DIW) in a simple cubic (SC) configuration. The filament diameter was 250 μm. Structures consisting of 4, 8, or 12 layers were fabricated with center-to-center filament spacing (“road width” (RW)) of 475, 500, 525, 550, or 575 μm. Three compressive load-unload cycles to 2000 kPa were performed on four separate areas of each sample; three samples of each thickness and filament spacing were tested. Geometry-dependent buckling of the SC structure was evident. At a given strain during the third loading phase, stress varied inversely with porosity. At strains of 25% and higher, the stress varied inversely with the number of layers (i.e., thickness); however, the relationship between stress and number of layers was more complex at lower strains. Intra-and inter-sample variability of the load deflection response was higher for thinner and less porous structures.

  • Gamma Radiation Aging Study of a Dow Corning SE 1700 Porous Structure Made by Direct Ink Writing
    2015
    Co-Authors: Ward Small, Cindy T. Alviso, Tom R. Metz
    Abstract:

    Dow Corning SE 1700 (reinforced polydimethylsiloxane) porous structures were made by direct ink writing (DIW). The specimens (~50% porosity) were subjected to a compressive strain of ~25% while exposed to a gamma radiation dose of 1, 5, or 10 Mrad under vacuum. Compression set and load retention of the aged specimens were measured after a ~24 h relaxation period. Compression set (relative to deflection) increased with radiation dose: 11, 35, and 51% after 1, 5, and 10 Mrad, respectively. Load retention was 96-97% for the doses tested. The SE 1700 compared favorably to M9763 cellular silicone tested under the same conditions.
