NYCOA nanoTUFF™ NT - 90-100 is Nylon 6 based Nanocomposite with 10% clay loading made via in-situ polymerization for optimum nano-clay exfoliation. NYCOA nanoTUFF™ NT - 90-100 can be tailor-made to any specific viscosity range, depending upon the final application. This grade offers a 100% improvement in stiffness vs. neat Nylon 6, and is comparable in stiffness to a 20% glass-filled Nylon. In addition, barrier properties to water, oxygen, carbon dioxide, and fuel are improved approximately 80% vs. neat Nylon 6.
