Applied Minerals Inc has completed trials incorporating its halloysite clay as a drop-in additive for reinforcement in polymer composites.
As a result of these trials, the company has filed a provisional patent application with the USPTO for a novel method of producing a halloysite-polymer composition that (i) eliminates two costly steps typically used in the compounding process and (ii) produces improved properties to other polymer composites reinforced with (a) halloysite nanotubes utilizing other composition methods, (b) chemically treated MMT organo/nanoclay and (c) certain tradyitional fillers. Examples of these property improvements are identified in the table below.
Applied Minerals intends to market its line of halloysite products under the company’s Dragonite brand name. the Dragonite line will consist of different grades of halloysite clay products tailored to enhance the property performance of each target application, in a cost competitive manner.
The Dragonite group of products is led by its first offering, Dragonite-XR, a drop-in additive specifically engineered for polymer reinforcement. Applied Minerals says that composites formed with Dragonite-XR exhibit not only high stiffness but also high tensile and flex strength, all with a low density and retained toughness. The company is currently exploring joint development opportunities with compounders interested in producing a line of polymer composites incorporating Dragonite-XR.
