To specify adhesive-backed felt, define the felt face, backing, actual bonding surface, dimensions and sample acceptance criteria together. “Self-adhesive” describes a construction; it does not establish whether a particular backing will suit your assembly.
Use this checklist for adhesive-backed sheets and cut parts or adhesive felt strips. Mark unknown requirements as open for review instead of choosing an unsupported material or adhesive grade.
Adhesive-backed felt RFQ checklist
| Specification | What to record |
|---|---|
| Felt face | Material or reference sample, thickness and units, color, required face finish, and any critical material values with their measurement methods. |
| Bonding surface | Substrate material, coating or paint, texture, curvature, and the surface condition at installation. Identify which face receives the adhesive. |
| Backing selection | An approved backing product code if available, or state that selection is open. Identify any restrictions on substitutions. |
| Part or strip geometry | Drawing revision, dimensions, units, tolerances, holes and cutouts. For strips, specify width, length, roll or cut-length format, and permitted joins if relevant. |
| Installation and use | How and when the part is applied, handling before use, expected temperature and moisture, movement, loading, edge exposure, and contact with cleaning agents. |
| Sample approval | The actual test surface or assembly, conditioning and observation period, agreed procedure, and acceptance criteria for the intended use. |
| Quantity and presentation | Sample quantity separately from production quantity, both with units. Include liner access, piece separation, packaging and identification needs. |
For thickness, density or areal mass, keep the value, unit and method together. See the felt material specification notes before comparing quotations that use different units or measurement conditions.
Which surface details affect the specification?
A substrate name alone may leave important information unanswered. “Metal” does not identify a coating, finish or surface condition. “Plastic” does not identify the material or the molded surface. Send a photo, substrate specification or representative sample when the bonding face is difficult to describe.
Record the cleaning process you actually use and any constraints on changing it. Agree installation conditions with the proposed backing supplier and sample approval team; do not copy a preparation method from an unrelated tape product.
How should an adhesive-backed felt sample be approved?
Start with the assembly requirement. Record whether the felt must remain in place during handling, tolerate movement, preserve its position at exposed edges, or be removed later. If removal is required, define acceptable residue and surface appearance as part of the approval criteria.
Use the intended substrate and installation procedure for the sample evaluation. A result obtained on a different surface or after different conditioning should be identified as such. Record the felt and backing references, drawing revision, installation conditions and evaluation date so that the approved combination can be reproduced.
Keep the proposed backing, felt and assembly conditions in an identified review record. The felt sample approval checklist includes a fillable worksheet for observations, decisions and outstanding checks.
Is a peel adhesion figure enough?
A peel adhesion result answers a defined test question. Ask for the method, edition, substrate, test conditions and reporting units before comparing figures. ISO 29862:2024 covers peel adhesion properties of self-adhesive tapes; whether a particular procedure is applicable to the proposed construction must be agreed for the project. A reference to this standard is not a product certification or a reported test result.
A peel figure alone does not document every installation or service requirement. Keep the actual assembly checks and acceptance criteria in the sample approval record.
Rolls, cut lengths or individual parts?
Specify how the felt will be handled at your workstation. A roll specification needs the required width and length. A cut-length specification needs the length and quantity of pieces. Individual shaped parts need a drawing and a description of how the liner should be accessed for installation.
If only part of the felt face should have backing, mark the backing area on the drawing. If backing coverage is still open, describe the installation problem and request a proposal for review rather than assuming a particular construction.
What should accompany the quotation request?
Send the drawing or dimensional sketch, substrate information, intended use, felt requirements, sample and production quantities, and your approval criteria. Separate mandatory requirements from preferences and items that remain open.
