Specialty Silicone Fabricators Inc. is nearing customer trials of ultraviolet-light-curable Addisil silicone elastomer from Momentive Performance Materials Inc. Both firms exhibited at the UBM Canon trade shows, held Feb. 8-10 in Anaheim.
SSF envisions use of the material in a combination product that may incorporate two or more regulated drugs or biological agents in a low-temperature-thermoplastic drug-eluting matrix.
We have had a couple of good runs with molding Addisil on a 100-ton injection press as well as extrusion equipment, said Frank East, marketing manager of Paso Robles, Calif.-based SSF. The material opens a wide array of things we can extrude and cure with UV light rather than the vulcanization process, East said.
SSF began working with Addisil-creator Momentive of Albany, N.Y., in January 2010 and has conducted internal testing in Class 7 clean rooms in Paso Robles and another SSF facility in Tustin, Calif.
Momentive demonstrated the benefits of two-component Addisil UV 60 EX silicone rubber for automotive profiles, gaskets and seals during the Fakuma trade fair in fall 2009 in Friedrichshafen, Germany. The firm had a U.S. compliance safety testing and research company conduct biocompatibility testing during 2010, according to Stacey Guilford. Guilford is Momentive health-care marketing manager for the Americas. In addition to drug-combination products, Addisil is viewed as a useful material for medical tubing and seals.
On Oct. 1, private equity affiliates of Apollo Global Management LLC of New York took control of the specialty chemical brands Momentive and Hexion through Momentive Performance Materials Holdings LLC of Columbus, Ohio.
