- Dragonite™-HP in Polypropylene
The advantages of Dragonite™-HP in PP include (1 wt% loading):
Mechanicals Improvement
- Modulus increased by 20 - 25%
- Strength increased by min. 20%.
- Impact resistance increased by 40% (notched Izod)
- Enhanced mechanicals provide ability to downgauge for thinner/lighter parts
Cycle Time Reduction
- Faster production through up to 25% lower cycle time by increasing the onset of cyrstallization of PP by approximately 8°C
- Extra savings in cycle time possible through downgauging
Other Benefits
- Improvement to creep resistance, surface hardness and HDT / Vicat softening temperature
- Dragonite™-HP in Nylon 6
The advantages of Dragonite™-HP in Nylon 6 include (1 wt% loading):
Mechanicals Improvement
- Modulus increased by 20%
- Strength increased by min. 10%
- Elongation to break retained at very high level
- Good processability even at 30 weight % Halloysite
In addition there is evidence that DRAGONITE-HP results in modification of the crystal phase forming type morphology.
- Dragonite™-HP in Polylactic acid (PLA)
Polylactic acid and its copolymers have attracted a lot of attention because it is one of the few thermoplastic materials derived from a natural, sustainable and biodegradable monomer. PLA is already commercial in packaging film but its properties must be improved if other applications such as injection molded parts and fibers are to be realized.
The advantages of Dragonite™-HP in Polylactic acid (PLA) include:
As an additive for injection molded PLA (2 wt% loading):
- Good mechanical properties attributed to good dispersion and a high level of interaction between the filler and polymer
- Modulus increased from 0.7 to 2.25 GPa (+220%) and ultimate tensile strength increased from 29.2 to 43.2 MPa (+48%).
- Elevated the mechanical properties of PLA to be competitive with polystyrene and other popular thermoplastic materials.
- Significantly increased the stiffness of PLA at elevated temperatures (HDT)
- Full retention of impact resistance
Incorporation into poly(lactic-co-glycolic acid) to make electrospun fibers:
- Modulus, ultimate tensile strength and elongation to break were all improved
- No detrimental effects on the fiber spinning operation due to excellent clay dispersion
It is especially fitting to use DRAGONITE-HP, a natural, biocompatible clay, as an additive to elevate the performance of PLA and other naturally derived polymers.
- Dragonite™-HP in Transparent Films
The advantages of dragonite-hp in films include:
- Provides for better mechanical properties even at low loadings
- Disperse readily in thermoplastics
- Provide a further boost in properties during monoaxial or biaxial orientation of the film
- Improved bubble stability through increased melt strength

- Dragonite™-HP in Nylon 6
Applications
- The hollow tubes can be loaded with oil to give a self-lubricating material with controlled release of lubricant over time
- DRAGONITE-HP can be incorporated in thermoplastic nylon or in the monomer when making cast nylon parts
- Dragonite™-HP in Transparent Films
Packaging is one of the major applications for polyolefins and other thermoplastic materials. Transparent films in particular are in demand. Due to the huge volumes of material used and intense competition, there is a continual drive to higher performance enabling down-gaging and ultimately, reduced materials cost. Traditional fillers have intrinsic limitations including loss of transparency, and difficulties in controlling particle size distribution and dispersion to the degree needed to enable continuous commercial production.
Transparent films containing 10 or 20 weight % DRAGONITE-HP have been produced. It has also proven possible to load the tubes with liquid actives which then release at a controlled rate. Applications for that include scented packaging and incorporation of natural oils that act as insecticides.
