Dragonite -XR Brochure

  1. 1. APPLIED MINERALS INC. TM 110 Greene Street, Suite 1101 New York, NY 10012 1.800.356.6463 Applied Minerals is a leading global producer of Halloysite Clay. Vertically integrated from mine to market, our niche focus and in-depth application knowledge allow us to offer our customers commercially consistent product grades, specifically tailored to achieve their enhanced performance objectives. Applied Mineral’s Halloysite products are offered under the DragoniteTM brand. Applied Minerals is proud to introduce Dragonite-XRTM, a drop-in additive specifically suited for polymer reinforcement. Dragonite-XRTM is naturally exfoliated due to its tubular shape and uniform surface charge. As a result, Dragonite-XRTM disperses easily in various thermoplastic and thermoset resins at loading levels up to 40%. This is a major advantage over layered silicate fillers that must undergo a complex and costly chemical exfoliation process. Dragonite-XRTM composites exhibit not only high stiffness but also higher tensile and flex strength, all with a lower density and retained toughness. Dragonite-XRTM in powder form 5µm SEM image of Dragonite-XRTM Crude ore of Dragonite-XRTM extracted from the Dragon Mine Advantages of Dragonite-XRTM in Composites Lower density than conventional fillers results in reduced weight of finished products. Naturally exfoliated morphology provides ease of dispersion at loadings up to 40% without a need for organo-treatment. This results in lower raw material, mixing, and quality control costs compared to organo clays. Increases both the stiffness (modulus) and strength of composite with minimal changes in impact strength, weld line strength, and viscosity. Improves fatigue resistance and drop impact resistance compared to chopped glass fibers. Acts as a nucleating agent with 8°C increase in crystallization temperature, even at 1-3 wt% level, resulting in faster cooling and cycle time. Improves thermal stability: 20°C increase in the decomposition temperature in TGA. Increases time to ignite, reduces peak heat release rate, and improves char density when added at 5-10 wt% with other conventional flame retardants. Lower shrinkage than organo clay and lower warpage than chopped glass fiber and mica. Increases stiffness and toughness of thermoset compounds. Tubular morphology enables the entrapment of active agents followed by their controlled- release at predetermined rates. Halloysite is an inorganic material that is non-toxic and biocompatible. Lower cost than organo clay.

PATENTED TECHNOLOGY US PROVISIONAL PATENT: Process for Polymer Composite with Inorganic Filler US PATENT NO: 6,280,759 Method of Controlled Release and Controlled Release Microstructures US PATENT NO: 5,492,696 Controlled Release Microstructures US PATENT NO: 5,705,191 Sustained Delivery of Active Compounds From Tubules with Rational Control US PATENT NO: 5,651,976 Controlled Release of Active Agents Using Inorganic Tubules Applied Mineral’s Dragon Mine: Utah, USA. Other DragoniteTM Applications & Uses Controlled Release Technology: As a carrier of active ingredients, the tubular nature of DragoniteTM Halloysite clay enables a product to maintain uniform and sustained release rates of an active agent, thereby reducing application frequency and initial overdosage. Release rates can be controlled through selection of tube diameter, length, and encapsulation. This increased efficiency of application reduces the amount of active agent needed to achieve desired results, translating into significant cost savings and environmental responsibility. Applications for Controlled Release: paints/coatings, building materials, agriculture, cosmetics, fragrances, pigments, electronics, fabrics, textiles, drug delivery fields and a range of other industries. Other Areas of Use: catalysts, molecular sieves, environmental remediation, filtration, technical ceramics, cosmetics, paint modifiers, tyre composites, proppants, drilling muds.
