Spectrum PETG ESD

Professional ESD Protection and Safety for EX Zones

Spectrum PETG ESD is a high-quality antistatic filament developed on the basis of a proprietary polymer blend designed to provide durable protection against electrostatic discharge (ESD). The material is intended for industrial and technical applications where reliability, safety, and precise surface properties are essential. It combines the mechanical strength typical of PETG with excellent layer adhesion and printability, while offering a unique matte surface finish that gives printed parts a professional appearance.

Unlike standard PETG filaments, Spectrum PETG ESD uses a permanent, non-migrating antistatic formulation whose performance is independent of ambient humidity. This means the material maintains its ESD-protective properties in both dry and humid industrial environments, ensuring consistent and safe protection of electronic components throughout their service life.

How Spectrum PETG ESD works

ESD (Electrostatic Discharge) is a phenomenon of sudden discharge of static electricity, which can damage sensitive electronic systems. Spectrum PETG ESD effectively prevents such discharges, ensuring that 3D-printed parts made from this filament are safe for use in contact with electronic devices and measuring equipment. The 3D-printed parts made from Spectrum PETG ESD exhibit a surface resistivity in the range of 10⁷–10⁹ Ω/sq, corresponding to the levels typically required for ESD (Electrostatic Discharge protection) and EX / ATEX safety, i.e., applications in potentially explosive environments.

The achieved resistivity values place Spectrum PETG ESD in the optimal functional range for ESD-safe materials, ensuring effective and controlled dissipation of electrostatic charges without the risk of sparking. The electrostatic energy is dispersed in the form of low-energy corona discharges, guaranteeing full safety of electronic components even in the absence of grounding.
