Product engineering brief
Battery Pack Fire Shields
Custom large-format shields specified by stack, exposure, attachment, weight and protected-side criteria.
The engineering problem
Start with the installed interface.
A shield must remain meaningful around seams, fasteners and penetrations after vehicle or ESS conditioning.
We convert candidate mica, aerogel or composite stacks and support drawing review for integration and validation.

Selection logic
Decision data customers and engineers expect
| Decision dimension | What must be defined |
|---|---|
| Stack | Document every layer, facing and adhesive. |
| Exposure | Define heat/flame source, duration and measurement points. |
| Attachment | Include seams, fasteners and penetrations in tests. |
| Condition | Test after agreed mechanical/environmental aging where required. |
Engineering data
Available parameters and validation status
| Parameter | Value / range | Condition | Method | Evidence state |
|---|---|---|---|---|
| Construction | Custom multilayer stack | Define with application | Grade / project specific | Customizable target |
| Thickness / areal mass | Project-specific | Define with application | Grade / project specific | Application validation required |
| Thermal/flame exposure | Full condition must be defined | Define with application | Grade / project specific | Application validation required |
| Geometry | Custom outline, seams and penetrations | Define with application | Grade / project specific | Customizable target |
Ranges are selection windows or material-family references, not universal guarantees. Final values are tied to the approved grade, converted construction, thickness, conditioning and test method.

Frequently asked questions
Clear answers before sampling
Can a shield be called fireproof?
No. Results apply only to the tested construction and exposure. Use condition-specific language.
Can the part be supplied in sections?
Potentially, but joints must be designed and represented in system validation.
Can VOLTFEND provide test samples?
Yes, after material availability, geometry and the intended test matrix are agreed.
