silicone foam gasket

Silicone Foam Sourcing turns a silicone foam gasket request into one specification list so several factories can quote on the same basis. A gasket is not a leftover sheet in a photo. It is a named thickness, cell structure, outline or drawing, plus packing that will appear on the invoice. We do not hold gasket inventory or publish a gasket price.

What every silicone foam gasket quotation must state

Two prices mean the same thing only when thickness is written in inches or millimetres on both replies. “Standard gasket stock” is not a thickness.

Thickness pair

State the thickness the incoming gauge will check. If the drawing uses a range, write the range and the inspection method.

  • Inches or mm
  • Tolerance if used
  • Compressed height
  • Which value governs
Request Datasheet

Outline

ID/OD, a DXF, or a paper template. A competitor part number is a reference the factory may or may not cross.

  • Drawing revision
  • ID/OD if a ring
  • Strip width
  • Kiss-cut vs full cut
Compare Grades

Inside versus extra

Ask which parts, liners and packing sit inside the gasket price and which are billed separately.

  • Adhesive liner
  • Release paper
  • Export carton
  • Tooling if any

Attached evidence

Each supplier attaches the current file for the quoted item, not a general capability brochure.

  • Dimensional page
  • Density method
  • Lot declaration
  • Sample first lot
Compare Grades

Cost lines commonly excluded from a silicone foam gasket quote

Ask for these lines in writing. A lower piece price that hides plates, liners or freight is a different deal.

Same-basis cost lines for silicone foam gasket quotes
Thermal Chemical Mechanical Compliance
Service temperature on the foam, not on the enclosure brochure Cleaning fluid named if the gasket sees wash-down Thickness in inches or millimetres on the invoice line Lot declaration for the quoted foam
Adhesive temperature if a liner is included Oil splash called out or marked not applicable Compression set method if the buyer uses it REACH SVHC if the plant files it
Sample versus production lot split Adhesive billed inside or outside the piece price Tooling or kiss-cut plate as a separate line Incoterms next to the money figure

Evidence list, not a capability wall

  1. Dimensional page — the outline or thickness that will be inspected, dated for the quoted revision.
  2. Density or cell statement — method and unit, not a family brochure sentence.
  3. ASTM or equivalent method — only the method the buyer named, with the condition it was run under.
  4. Plant ISO 9001 — optional system file; it does not replace the lot page.
  5. FDA 21 CFR 177 — only when food-contact is written on the request and the file names grade plus lot.

How the same request is issued

Silicone Foam Sourcing sends one written list to more than one factory. Replies are laid side by side on thickness, packing, Incoterms and documents. We do not recast a different Incoterm as a percentage saving.

  • Quantity against each configuration, not as a lump.
  • Destination state or postal code and a requested delivery window.
  • Whether a sample must be approved before the production lot.
  • Drawings sent after the first reply; this form has no upload field.

Start the gasket brief

Write cell structure, thickness and density; quantity with unit; destination state or postal code and requested delivery / lead time; required product documents and sample needs. Optional target budget with currency and unit or whole-order basis; optional supplier preference. Drawings can be sent after we reply; this form has no upload field.
