A cushion must perform after loading, not only feel soft when first touched. Compare foamed silicone candidates under a defined loading history and assess recovery using specimens that represent the actual part thickness and contact arrangement.
Evaluation scope
Foaming liquid silicone rubber should be qualified as a material-process-geometry combination. A catalogue application does not establish the foam structure, cured dimensions or performance in a particular enclosure. The evaluation below is a development plan for the JY-920 candidate, with processing instructions and acceptance values to be confirmed from current supplier documentation.

Keep these variables in the record
| Item | What to record |
|---|---|
| Geometry | Record cavity size, venting and fill access. |
| Material | Confirm the exact grade and supplied components. |
| Process | Document supplier-approved mixing and curing conditions. |
| Function | Separate cushioning, sealing and thermal requirements. |
Trial and review plan
- Identify the assembly's expected compression and movement without assuming the foam will accommodate every tolerance. Define the test geometry and conditioning procedure.
- Apply the agreed loading sequence consistently to control and candidate specimens. Record force response or deformation using a method suited to the design question.
- Measure recovery after a defined rest period and inspect for damage. Where the application requires it, repeat after relevant environmental conditioning.
How to use the results
Interpret short-term compression and longer-term recovery separately. A softer initial response is not automatically the best choice if the assembly requires retained support. Qualification should reflect the real contact area and mechanical constraints.
Information to include in an RFQ
Provide a drawing, target function, substrate materials and intended manufacturing method. Request grade-specific processing, safety and technical documentation. Ask for evidence applicable to the proposed cured form; do not treat general silicone properties as certified assembly performance.
Frequently asked questions
Can a hand-squeeze comparison replace mechanical testing?
It can help early screening, but it is not a reproducible acceptance method. Use defined specimens, loading and measurement conditions before specifying a material for production.
Are these proposed checks certified results for this grade?
No. This article describes evaluation and procurement questions, not completed customer trials. Request current grade-specific documents and appropriate test evidence. The acceptance criteria must fit the actual formulation, process or assembly being qualified.
