Applied Minerals produces Dragonite-XRTM, a naturally exfoliated halloysite clay additive for polymer reinforcement. Dragonite-XRTM disperses easily in polymers at up to 40% loading without chemical treatment, increasing stiffness, strength, and thermal stability while maintaining toughness. It provides advantages over traditional fillers like glass fibers or organoclays by enabling weight reduction and easier processing at lower cost. Applied Minerals markets Dragonite-XRTM for applications requiring improved mechanical and physical properties in composites.

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.

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.

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.
