What it is for

ESD resin is used for tools and fixtures that touch electronic components sensitive to electrostatic discharge: trays and nests for boards, assembly and test jigs, grippers, guides, covers of workstations. It is a dissipative material: it lets charges drain away in a controlled way instead of building them up or releasing them all at once.

Do not choose it as an insulator or as a conductor, nor for parts that work in heat: the data sheet reports a heat deflection temperature of 62.2 °C at 0.45 MPa. For jigs with no electrostatic requirement the Tough resins are enough; for very stiff tools, Rigid 10K.

Typical values from the makers' data sheets, measured on specimens under the conditions stated. They are not guaranteed design values: for a critical application ask us for a test on your part.

Treatments after printing

The values in the table are for parts post-cured for 60 minutes at 70 °C, as the maker's data sheet states.

These are the limits of the process, the same for every variant unless stated. For critical dimensions, talk to us before printing.

Which variant to choose

ESD is the only static-dissipative resin in our catalog. If your tool does not touch sensitive components, the Tough resins give more toughness; if it has to be very stiff, Rigid 10K.

FAQ

Frequently asked questions

A dissipative material has an electrical resistance between that of an insulator and that of a conductor: the charges built up by rubbing drain slowly to ground, with no sudden discharge. That is what is needed to handle boards and sensitive components: the part does not build up charge and does not release it all at once onto the component.

After a 60-minute post-cure at 70 °C the data sheet reports a tensile strength of 44.2 MPa, a modulus of 1.937 GPa and an elongation at break of 12% (ASTM D638), with a hardness of 90 Shore D (ASTM D2240). It is a stiff resin, tough enough for jigs, nests and grippers used every day on the line.

Dissipative behavior is a property of the material, stated by its maker. We issue no declaration of conformity to ESD standards on the printed part. If your protected area requires a check, measure the part with your own instruments or write to us before asking for a quote.
