Dragonite-HPTM is a patented halloysite clay additive that provides both reduced cycle times and reinforcement to polyolefins. It has been proven to reduce cycle times in injection molding, blow molding, compression molding, and rotational molding processes by up to 30% depending on the resin and process. Case studies demonstrate significant cycle time reductions of 15-25% and cost savings through increased part throughput when using only a 1% loading of Dragonite-HP in various polyolefin processes and applications.

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

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
