Bomar and Mechnano unveil E35B+ masterbatch for ESD 3D resins

“Mechnano’s Product Development team is committed to improving our technologies and AM solutions,” says Mechnano Director of Applications & Technology Dr. Olga “Dr.O” Ivanova. “This dedication has led to the development of a new masterbatch that delivers excellent results while requiring a smaller quantity in the final resin formula, making it more cost-effective.”

E35B+ offers 2.5 times higher CNT concentration compared to Mechnano’s original E35A ESD Masterbatch. It is particularly suitable for the development of SLA, DLP, or jettable 3D printing resins that require rigidity and high tensile strength. With adjustable resistivity ranging from 10⁶-10¹⁰ Ω, E35B+ ensures absence of carbon trails and can be effortlessly incorporated into a formula without the need for high shear mixing.

“This new, more highly concentrated dispersion by Mechnano should improve the versatility of this product and further enable ESD resins for a wide range of applications,” says David Robitaille, Global Brand Director for Bomar. “Mechnano has continued to enhance the product’s design and manufacturing process to improve performance, and we’re excited to see what this new dispersion can enable.”

E35B+ offered by Mechnano makes use of their unique D’Func process. This process is designed to address the issue of clumped and roped carbon nanotubes (CNTs) in materials, ultimately improving their mechanical and electrical performance. By eliminating these clumps and functionalizing CNTs, Mechnano ensures that their masterbatches provide stable CNT dispersions. This is crucial because dispersions of clumped CNTs are known to negatively impact the mechanical properties of materials, leading to inferior part performance. Mechnano’s product lineup is constantly expanding, and E35B+ can be obtained directly from Mechnano or through their partner Bomar.
