EP-SL
Seven slurry grades mapped one-to-one onto the powders: EP-LP09S becomes EP-SL09S. Changing form does not mean a new part number or a new approval file — the least work on your side.
| Slurry grade | Base powder | D50 (μm) | pH | Typical application |
|---|---|---|---|---|
| EP-SL09S | EP-LP09S | 1.8–2.0 | 6.5–7.5 | Crystal and diamond products |
| EP-SL11S | EP-LP11S | 2.3–3.2 | 6.0–8.0 | Optics and phone covers |
| EP-SL09P | EP-LP09P | 1.6–2.0 | 6.5–7.5 | TFT-LCD substrates and 3D glass |
| EP-SL10S | EP-LP10S | 0.8–1.3 | 6.5–7.5 | Silicon wafers and precision optics |
| EP-SL07XS | EP-LP07XS | 1.3–1.7 | 6.0–7.0 | Covers and 3D glass (red slurry) |
| EP-SL01LS | EP-LP01LS | 0.8–1.4 | 6.5–7.5 | Large flat glass |
| EP-SL08S | EP-LP08S | 0.85–1.25 | 6.5–7.5 | Silicon wafers and optical glass |
Grey rows are grades in production whose parameters we have not measured for publication — request the batch TDS and you get measured values.
Slurry grades mirror the powder codes, but solids content, viscosity, 24-hour settling and bath life are not yet measured, so none of them are published. Tell us your polisher and circulation setup and we match the formulation and send a sample. EP-SL11S ships as a concentrate; dilution is set against your site water, not a universal ratio.
Every figure on this page comes from the COA and TDS shipped with the goods. Grades that are not measured are listed by code only.
ENGINEERING NOTES
Sets removal rate and freight cost. High solids save freight but settle; low solids stay stable but need more circulation.
Drives pipe transport and distribution uniformity on the pad, which in turn drives flatness.
The most overlooked number: fast settling means concentration drifts within a batch, and yield drifts shift to shift.
| Item | Powder EP-LP | Slurry EP-SL |
|---|---|---|
| Freight | Priced on dry basis; lowest unit freight | More than half is water; cross-border freight is clearly higher |
| Make-up | Needs dispersion equipment and stable water quality | Ready to use at a fixed dilution |
| Concentration stability | Mixed fresh, no settling issue | Stratifies if circulation or agitation is weak |
| Switching cost | Same numbering; process parameters need re-tuning | Same numbering; no new purchasing code to create |
| Better fit | High volume with an existing slurry plant | Medium volume, automated lines, frequent changeovers |
Solids content, viscosity, settling rate and bath life depend on the actual formulation and must be measured. No estimates are published here — tell us the grade you need and you get the measured report for that batch.
These grades are in production, but we do not publish numbers we have not measured. Request the TDS and you get the real batch data.
The batch TDS and COA come back within 24–48 hours. Standard-grade samples ship in 3–5 working days; minimum one pallet.
Request TDS / quoteMaterial, machine, target result: three lines are enough. Grade recommendation within 48 hours; standard grades in stock, samples in 3–5 working days.
