Objective: • Reduce coefficient of thermal expansion (CTE) and
increase strength without affecting impact resistance • Reduce warpage as interlocking parts require tight
tolerances Solution: • CTE reduced with just 1.0% loading of Dragonite-HP • Substantial cycle time reduction • Improved strength and stiffness give the opportunity for
thin-walling to reduce weight in next generation product
Heavy-Duty Large Mat & Temporary Roadway System (HDPE)
Case Study: Compression Molding
Drop-in solution: Significant cycle time reduction
With a 1 wt% Dragonite-HP loading, the customer achieved:
• 25% reduction in cycle time resulting in significant manufacturing cost reduction • Improved strength and modulus over the control • Eliminated sink marks while also improving surface appearance

Cost per part ($) $8.07 $7.53 7%
Net Effec3ve Cost of HDPE ($/lb) $0.85 $0.76 11%
Case Study: Injection Molding
Case Study: Rotational Molding
Objective: • To reduce cycle time and reduce weight of rotational molded part Solution: • 15% cycle time reduction with just 1.0% loading of Dragonite-HP • 16% weight reduction of the part by thin walling due to the increased
strength • Fixed part defects
