Huber Engineered Materials (Atlanta, Ga., USA), a division of the J.M. Huber Corp., announced on Jan. 14 that Gary Rex, Ph.D., thermoset manager for alumina trihydate (ATH) and magnesium hydroxide (MDH) products, and Bob Baker, technical service director for calcium carbonate and barium sulfate products, will deliver an educational session at the upcoming Composites 2010 exhibition and convention, Feb. 11 at the Mandalay Bay Resort in Las Vegas, Nev. The paper is titled, “How Fillers Affect Composites Manufacturing.”

The session will focus on the important role fillers play in composite part fabrication and how common and uncommon fillers are used in developing the composites matrix. Participants will learn how filler chemistry, particle shape and size and even the mine location can affect the quality of the final part. Baker has more than 40 years of technical experience working with minerals and is looking forward to the opportunity to present the session and share his broad industry knowledge.

Part one of the session will focus on calcium carbonate and other frequently used industry minerals used in composites, while the emphasis in part two will be how the physical properties, viscosity and color of flame retardants impact the manufacturing process. “Our session will be full of educational information that will help companies make key filler input decisions for future processes,” says Rex. “An example is alumina trihydrate [ATH], a raw material used in composites. In the discussion, we will talk about how ATH is manufactured, its differences in color, applications, its particle-packing capabilities and how the material gives the formulator lower viscosity. We’ll also present similar information for other minerals.”

At its booth in the exhibition hall Huber is showcasing its Granite Elite textured pigments and Hymod surface-modified and MoldX optimized grades of ATH along with its Marble Elite Alpha cultured marble filler and Hubercarb and Optifil ground calcium carbonate grades for bulk and sheet molding compounds and contact molding applications.
