Grade designation
The supplier’s own grade name plus the ASTM or equivalent method. If they used ASTM D2000, the callout has to be complete enough that a second factory can read it.
This page is the spec check for a leftover measured string: remove mold from silicone rubber water bottle. Buyers paste it when they mean a consumer cleaning question, a bottle-molding compound, or a factory that can mold a bottle. Those are different goods. The quoted item either satisfies the written configuration or only resembles the wording.
Silicone Rubber Sourcing does not publish a cleaning recipe, a mold-release brand, or a bottle SKU. We ask which published figure and which standard were used to state grade designation and the applicable ASTM method.
Is the buyer buying a finished water bottle, a silicone rubber molding compound for a bottle tool, sheet stock, or advice about mold growth on an existing bottle? Only one of those belongs on an RFQ.
Sheet stock, molding compound, softer, harder or color-matched. If none fit, say so. Do not let a salesperson convert a photo into a “close enough” line.
Ask which published figure and which standard named the grade. A plant certificate is not a lot test. A cleaning blog is not a TDS.
If the supplier proposes a different remove mold from silicone rubber water bottle model, re-issue the changed axes: hardness, density in g/cc, temperature, ASTM, quantity and packing.
The supplier’s own grade name plus the ASTM or equivalent method. If they used ASTM D2000, the callout has to be complete enough that a second factory can read it.
Shore A or Shore D with method. Density in g/cc only when the buyer uses it to distinguish filled from unfilled or sponge from solid.
FDA 21 CFR 177 or the named food-contact file for the quoted grade and lot. A “BPA-free” marketing line is not that file.
Platinum or peroxide, translucent or pigmented. Mold-release residue on a finished bottle is a process question for the molder, not a hardness number this desk can invent.
Decides whether the leftover string is a cleaning question, a molding job, or a sheet buy. Writes quantity and destination.
Owns the grade file, the lot test, the mold, the bottle, and the commercial terms.
Repeats the axes, flags when a quote only resembles the wording, and does not issue a material certificate.
US installation, bottle washing services, mold-remediation contracting, or a guaranteed lowest price.
These are process counts, not ESG scores, savings percentages or customer totals.
If the factory changed hardness, density or ASTM, treat it as a new request. Keep the original line on file.
