A multi-grade product page is useful for finding a material family but cannot replace a grade-by-grade comparison. Build the RFQ around the information that affects the design and ask the supplier to identify which candidate best fits the intended encapsulation process.
Evaluation scope
The catalogue groups JY-9200(AB), JY-9220(AB) and JY-9230(AB) as two-component thermally conductive liquid silicones. A grouped listing does not establish identical properties across the three grades. Identify the exact candidate and obtain its own processing and property information before using the following encapsulation evaluation plan.

Keep these variables in the record
| Item | What to record |
|---|---|
| Grade | Specify the exact member of the listed product group. |
| Cavity | Record depth, obstructions and filling access. |
| Components | Include coatings, plastics and sensitive interfaces. |
| Validation | Keep thermal, electrical and mechanical checks distinct. |
Trial and review plan
- List required properties and manufacturing constraints in separate columns. Mark unavailable values as pending rather than filling them from another grade in the family.
- Request current data sheets and test methods for each proposed candidate. Confirm component pairing, process instructions and the supplied material form.
- Compare shortlisted grades in the same representative assembly. Record differences in filling, cure and required functional tests before selecting a production specification.
How to use the results
A decision table should expose missing information, not conceal it behind a common family name. Do not rank grades using values measured by incompatible methods or conditions. Resolve the comparison basis with the supplier before a purchase decision.
Information to include in an RFQ
Supply the encapsulation drawing, component materials, thermal objective and manufacturing constraints. Request the exact grade's technical and safety data, ratio and cure instructions. Ask for relevant electrical or environmental test evidence without assuming that a grouped catalogue entry supplies it for every grade.
Frequently asked questions
Are the three grades interchangeable because they share one listing?
No such equivalence follows from the listing. Obtain grade-specific documentation and validate the selected material in your process, especially when making a substitution after initial approval.
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.
