17 mm hydrophobic & anti‑slip lens blocking pads/stickers for Nidek edging. Let me know if you want help sourcing or choosing exactly what fits your setup.
✅ What Exists / Key Specs
(there are rolls of blocking pads / stickers for Nidek edging machines with roughly 17 mm or in that size range.
Here are some typical properties:
| Property | Sample Value / Range |
|---|
| Diameter / Spec Size | 17 mm (intended to match Nidek blocking cups) |
| Material | EVA foam base (≈85% EVA + 15% paper backing) |
| Thickness | ~0.8 mm common in some listings |
| Adhesive Type | Double‑sided adhesive, sometimes with special formulations / “imported glue” for better grip on hydrophobic or super‑slip coated lenses |
| Coatings Supported | AR, HMC, hard coat, hydrophobic or super‑hydrophobic coatings |
| Removal | Some are “easy remove without residue” type. |
⚠️ What to Check / Be Careful Of
To ensure the blocking pads perform well when edging hydrophobic lenses, especially with Nidek equipment, you’ll want to check:
Adhesive strength + compatibility
Hydrophobic coatings tend to repel liquids (including adhesives). The glue must be formulated to stick well on slippery coatings without peeling off during edge grinding.
Durability / edge stability
Does the pad resist deformation under the torque / pressure of the Nidek edging machine? If the pad compresses unevenly, edges may be inaccurate.
Residue after removal
You want a pad that peels off cleanly. Some adhesives leave residue which can damage coatings or interfere with later cleaning.
Correct geometry / shape
The blocking cup or fixture must completely contact the pad. 17 mm is typical for certain Nidek models; make sure it matches your model.
Thickness / flexibility
Too thick might cause misalignment; too thin might compress or break. ~0.8 mm seems common.
Slip resistance on hydrophobic / super‑hydrophobic surfaces
Sometimes combining anti‑slip discs or using a pad + disc combo helps. Some listings mention this.
