Insight Polymers introduces CNT masterbatches that significantly improve mechanical properties for 3D printing applications.
Insight Polymers & Compounding has developed a line of carbon nanotube (CNT) concentrates that improve tensile strength and stiffness by 20% to 100% while maintaining impact strength.
The company has formulated these CNT masterbatches specifically to enhance 3D printing materials. They can be incorporated into associated carrier materials with loadings of 2% to 7% by weight in the final compound, improving electrical resistance, impact strength, stiffness, and strength, varying by polymer and loading.
“While we are initially offering the concentrates in PP, PETG, PA 6, PA 66, PA 12 and PPS, we can customize compounds with specific polymers and loadings to develop a material that meets a customer’s requirements and unmet needs,” said Matt Torosian, Insight Polymers sales and market development manager. The company will add polymers to its concentrate portfolio by the end of second quarter 2025.
The masterbatches are also suited for electrostatic discharge protective packaging, electronics storage bins, conductive components in electronics assemblies, and electrostatic processing. Target vertical markets include appliances, automotive and drones.

A.J. Pasquale, Insight Polymers director of operations, said: “While CNTs have improved properties since they’ve been commercially available, our compounds exhibit the first significant measurable increase in mechanical properties of a thermoplastic compound.” Their lightweight and lower loadings translate to lighter, stronger end products with excellent conductivity, consistent electrical properties, and high cleanliness.
