buna rubber sheet

Does the quoted item genuinely satisfy buna rubber sheet, or only resemble it? This page is a document dashboard. It is not a laboratory we operate and not a certificate we issue.

Four panels to read before you accept a line

Identity

Invoice description mapped to one inquiry form: standard-size, cut-to-size, black or colored, UV-stabilized or thicker-gauge. If the factory names none of these and none of your axes, send the offer back.

Published figure

Which number and which standard were used to state color/finish and the applicable ASTM method? Shore A, thickness in inches or millimetres, or ASTM D2000. A screenshot without the method is not a figure.

Condition

New mill, leftover plate, recycled-content or reprocessed compound. Those are different goods even when the search string is buna rubber sheet.

Limits we will not hide

NBR swells less in oils than EPDM but ages faster outdoors. Silicone survives a wider temperature window but swells in many hydrocarbons where FKM holds sealing force. This desk will not smooth those limits into a marketing sentence.

What to request instead of a download wall

  • Current dimensional page

    Quoted thickness and sheet size. Not a 2019 family catalogue. We do not host a fake PDF library.

  • Named ASTM report

    Method and condition. If the buyer asked for D2000, a generic “rubber typical values” table is the wrong file.

  • Lot-tied regulatory file

    FDA 21 CFR 177, REACH SVHC or Prop 65 only when the brief asked, and only when the file names the grade.

  • SDS / TDS for the quoted compound

    Useful when oil, heat or outdoor duty is in scope. Still a factory document.

If the supplier proposes a different buna rubber sheet model

  1. Stop treating it as the same line

    A different density, color, hardness or process is a new request. Keep the original axes on file.

  2. Re-state hardness and ASTM

    Ask which published figure and which standard now apply. Do not accept “equivalent” without the method.

  3. Re-check color/finish

    Black NBR and a colored blend are different goods. Write the finish that will appear on the invoice.

  4. Re-issue quantity and destination

    The pallet count and US destination stay on the new line so later batches can be compared with the approved item.

Send the buna rubber sheet axes you can already prove

We will ask factories for the page that belongs to the quoted item. We do not certify the compound.
