CNC: An Excellent Carrier for Nano-particles

Valentis Core Technology

Improve polymer qualities while maintaining/reducing costs:

• Lighter

• Stronger

• Provides spectrum control while still transparent

• Higher recyclability (CNC is biodegradable)

• Can be tailored for the customer needs

• Super hydrophobic surface
