silicone foam rubber

Check whether the quoted item genuinely satisfies silicone foam rubber, or only resembles the family name. Silicone Foam Sourcing does not reprint a service-temperature table as its own number. Ask which published figure and which standard were used to state service temperature in °F or °C.

Confirmation path when the model changes

If the supplier proposes a different silicone foam rubber model, treat that as a new request. Re-issue the line with the changed axes visible. This path is a document check, not an ESG claim by this desk.

  1. Name the quoted form

    Closed-cell, open-cell, sheet, roll/strip or adhesive-backed. A neighbouring wording is useful only when the factory writes that it is the same configuration.

  2. Read the published temperature

    Copy the figure and the standard from the current datasheet that belongs to the quoted item. If the page has no method, the temperature is not yet comparable.

  3. Separate PCR or reprocessed content

    New, leftover, recycled-content or reprocessed foam are different goods. Ask for the statement if the receiving plant will be asked for it. Do not treat a PCR ask as a carbon number this desk verified.

  4. Re-check the swap

    Thickness, density in g/cc, cell structure, Shore A if used, and the temperature method all have to be re-stated. Keep the original line on file.

PCR content

Ask only if the buyer named recycled content. The factory states a percentage and the stream. This desk does not publish a PCR target year.

kg CO2e/kg

Request an LCA page if the brand-owner brief requires it. Figures stay on the supplier document. They are not site credentials.

Recyclable design

Adhesive-backed foam is often a mixed stream. Write whether the liner and foam must be separable. Do not assume a recycling route.

What has to be re-checked on a model swap

A different catalogue code can keep the family name and still change the foam. These asks travel with the new line.

REACH

Restate SVHC against the new compound if the duty requires it.

RoHS

Only if the receiving plant still files electrical-adjacent goods.

FDA 21 CFR 177

The file must name the new grade and lot, not the previous one.

ISO 9001

Plant system file; still not a substitute for the new dimensional page.

UL 94

Flame rating is thickness-specific. Re-ask at the quoted thickness.

ASTM method

Density, compression set or hardness method and condition on the new item.

Documents to request, grouped by type

This desk does not host downloadable certificates. Use the groups as a checklist when you write the supplier.

Product pages
  • Current datasheet for the quoted silicone foam rubber item
  • Thickness and density page with units
  • Cell-structure statement (closed or open)
Methods
  • ASTM or equivalent method for density
  • Compression set method if the buyer uses it (condition and time)
  • Shore A method if hardness is on the request
Lot files
  • Material declaration for the shipped lot
  • Dimensional report against the approved outline
  • Origin of melt or finishing if the plant will be asked
Regulatory asks
  • REACH / RoHS statements on the quoted foam
  • FDA 21 CFR 177 only with grade plus lot
  • UL 94 only at the quoted thickness if the duty names flame

Limits this check will not remove

  • A family brochure does not stand in for the quoted thickness.
  • Shore A and Shore D must not be mixed on the same line.
  • Working pressure in psi is not a foam-sheet axis unless the part carries fluid; do not copy hose tables onto foam.
  • Food-contact or flame conclusions are not issued by this desk.
