EUREKA, UT / ACCESS Newswire / September 17, 2026 / Applied Minerals, Inc., (the "Company") a leading supplier of highly pure halloysite clay products, marketed under the DRAGONITE trade name, is pleased to Introduce its DRAGONITE-BP-D501M grade for biopolymer composites requiring improvements in impact resistance, flexural strength and heat deflection temperature.
DRAGONITE-BP-D501M is a halloysite clay-based functional filler specifically developed for biopolymer composites. The surface chemistry of DRAGONITE-BP-D501M enhances the filler's adhesion to biopolymers, resulting in an improvement in a number of physical properties. Furthermore, the addition of DRAGONITE-BP-D501M enhances the nucleation of the biopolymer composite.
A third-party evaluated the performance of DRAGONITE-BP-D501M versus the leading micronized talc in a PLA composite. The PLA composite control included 11% w/w of cellulose fiber as well as a standard impact modifier. The following results show that DRAGONITE-BP-D501M significantly outperformed the leading micronized talc product per ASTM D1709-24 (Free Falling Dart Test).
PLA -3001D (%) | Fiber (%) | Impact Mod. B-500 (%) | Filler | Filler (%) | Failure Height (mm) | Potential Energy at Failure (gxmm)* | Improvement over control (%) |
69 | 11 | 20 | NONE | 0 | 60 | 30,000 | 0 |
64 | 11 | 20 | DRAGONITE-BP-D501M | 5 | 77 | 38,500 | 28 |
59 | 11 | 20 | DRAGONITE-BP-D501M | 10 | 80 | 40,000 | 30 |
64 | 11 | 20 | MICRONIZED TALC | 5 | 53 | 26,500 | (12) |
59 | 11 | 20 | MICRONIZED TALC | 10 | 53 | 26,500 | (12) |
| * The tested composites were compression molded into 3" x 3" x 0.125" plaques. Each plaque was conditioned at room | |||||||
| temperature for 24 hours before testing. Each plaque weighed 500 grams. ASTM D1709-24 was followed. The DRAGONITE- BP-501M, micronized talc and fiber were dried prior to compounding. | |||||||
