Grade-specific buying brief
Prepare a grade-specific HPEG raw-material inquiry
HPEG is purchased for a PCE synthesis route, not as a ready-to-dose concrete admixture. Identify the current raw material and the proposed grade change so the formulation team can define the comparison. A nominal 2400 label is only part of the buying identity; it should be accompanied by the chemical description and current specification.
Request units and test methods for hydroxyl value, water and double-bond retention, and the concentration used for pH. The available HPEG-2400H supplier batch report describes its own named lot. It does not establish future-shipment acceptance limits or certify a different HPEG grade. Confirm current lot documentation separately from the synthesis and finished-concrete evaluation.
