Polycarbonate with a conductive filler bringing surface resistance from above 10¹³ into the 10⁷–10⁹ ohm/sq dissipative band while holding Tg at 143 °C. The most expensive material in this group.

Applications

ESD PC addresses a specific conflict in electronics tooling: a fixture must hold its shape and survive handling, yet an ordinary insulating polymer can retain unwanted charge. A dissipative formulation provides a controlled electrical path while the PC matrix supplies useful mechanical and thermal performance. Stratasys explicitly lists tools, jigs, fixtures and assembly aids for PCB production and electronics manufacturing as applications for its PC-ESD material.

Its advantage is charge management in a mechanically durable locating part, rather than conductivity for carrying power. Electrical resistance depends on the formulation, printing process and environment, so the fixture needs a suitable grounding path and measured performance. Filled PC also has limited elongation, directional printed strength and moisture-sensitive processing; snap features and thin mounting arms need particular care.

How to read these values

Values describe representative grades, not every spool. Manufacturer datasheets and independent tests retain their source labels and dates. Printed orientation, test method, conditioning and formulation can change results. Unknown values are —. A listed use is not a certification. Shore A, Shore D and Rockwell hardness are separate scales.
