How to request and evaluate a silica sample set from Sensilchem

In short: Tell us the process problem, the material you use now, the formulation or resin, the equipment and the target; we reply with a proposed sample set — a main grade plus one or two comparisons — and a short test plan. Run the set beside your incumbent under identical conditions, record the results in one table, and send it back. Fit is confirmed on your line, and documentation follows the grade you choose.

What you need

  • A clear description of what is failing (caking, haze, foam, blocking, settling)
  • The material currently used and the level at which it is used
  • Your own laboratory or line time for a side-by-side comparison
  • Destination country and the approximate annual volume, so documentation can be matched

Step by step

  1. Describe the problem, not the product

    Write to nina@sensilchem.com or use the enquiry form. The most useful enquiry names the failure the plant sees and the conditions it happens under; a grade code alone tells us less than a sentence about the line.

  2. Receive the proposed sample set and test plan

    We reply with the grade we would test first, the comparison grades we would put beside it, and the dimensions to read. If a track has a scope limit — inert carrier only, candidate substrate only — it is stated here, before anything ships.

  3. Confirm the documentation you will need

    Tell us the destination country and the use. Technical data sheet, specification sheet, COA and SDS are issued per enquiry so that the revision and the market position are right for your case.

  4. Run the set beside the incumbent

    Same system, same loading, same day, same equipment. Every how-to guide on this site follows that rule because every result that ignores it is arguable.

  5. Record results in one table

    Incumbent in the first column, candidates beside it, one row per test dimension. Photographs of panels, trays or tubes carry more weight with your own management than adjectives.

  6. Send the table back and decide the next step

    We read the results with you: move up or down the gradient, change the treatment route, or go to a production trial. A typical first order is 200 kg to 1 tonne — enough to run the line, not fill a warehouse.

Mistakes that spoil the comparison

  • Asking for 'the best grade' without describing the process.
  • Testing the candidate at a different level from the incumbent.
  • Skipping storage or ageing steps because the first result looked good.

Questions we get asked

How long until samples arrive?

Samples normally ship within a few working days of the test plan being agreed, by courier.

Is there a charge for samples?

Sample material is free of charge for qualified enquiries; courier cost for the first shipment is usually carried by the customer.

Tell us what is failing in the process

The material you use now, the formulation or resin, the equipment and the target you need to hit. That is enough for us to say whether we have something worth testing.
