In pad printing, silicone behavior directly affects image transfer, edge clarity, and printing stability. A pad that is too soft, too hard, or poorly matched to the substrate may reduce print quality even when the machine and ink are correct.
That is why pad printing silicone should be chosen based on part geometry, print area, surface curvature, and transfer needs, not just Shore hardness.
Hardness affects deformation, contact behavior, and print suitability on flat or curved surfaces.
Good rebound helps maintain pad performance and repeatability in continuous production.
A suitable silicone surface behavior supports cleaner image transfer from plate to part.
Stable pad behavior matters in production environments where repeat printing is critical.
| Pad Printing Series | Hardness (Shore A) | Mixing Ratio | Viscosity (mPa·s) | Working Time (25℃, mins) | Curing Time (25℃, hrs) | Tear Strength (kN/m) | Tensile Strength (MPa) | Elongation (%) |
|---|---|---|---|---|---|---|---|---|
| PP-30 | 30 ± 2 | 9A : 1B | 6000 ± 1000 | 20 ~ 30 | 4 ~ 6 | ≥ 20 | ≥ 7.2 | ≥ 420 |
| AP-30 | 30 ± 2 | 9A : 1B | 8000 ± 3000 | 20 ~ 30 | 4 ~ 6 | ≥ 22 | ≥ 7.6 | ≥ 420 |
Often caused by poor hardness matching or unsuitable pad behavior.
May be linked to pad geometry and rebound mismatch.
It can result from an unsuitable selection of silicone for the production rhythm.
A single pad silicone may not perform equally well across flat, curved, and detailed surfaces.
We help buyers choose pad printing silicone based on part surface, pad design, image transfer requirements, and production conditions. For suitable applications, we also discuss hardness and performance direction rather than offering one universal formula.
That depends on the part surface, image area, and pad shape. Hardness should be selected based on the real print job.
No. Harder silicone is not always the best choice, especially on curved or uneven surfaces.
Yes. Send your part type, print area, and process background for a practical recommendation.
Tell us your application and print conditions for a suitable grade suggestion.
