EV & Energy Storage

EV Thermal Interface Seal Compound Review

Challenge

A cooling interface required stable compression under glycol exposure, thermal cycling, and repeated assembly handling.

RubberQ Response

RubberQ compared EPDM, HNBR, and FKM options, then built the testing path around compression set, coolant swell, and dimensional repeatability before quoting tooling.

Project Records

• Compound shortlist with service-window rationale
• Compression-set and coolant-swell test plan
• Batch traceability path for future repeat orders

Industrial Equipment

Hydraulic Valve Seal Migration From Commodity NBR

Challenge

A valve program needed better oil aging and extrusion resistance without over-specifying a premium fluoroelastomer.

RubberQ Response

RubberQ compared NBR and HNBR formulations against the drawing groove, pressure window, and target maintenance interval.

Project Records

• Material recommendation tied to pressure and oil exposure
• Pilot-run inspection plan
• Incoming and final inspection record template

Semiconductor

Semiconductor Vacuum Module FFKM Seal Path

Challenge

A process-module interface required chemical resistance, low contamination risk, and lot-level traceability for maintenance planning.

RubberQ Response

RubberQ scoped an FFKM sealing package with low-outgassing compound selection, flash-control targets, and clean-process handling requirements.

Project Records

• FFKM material path with contamination-control notes
• Lot-level traceability requirement
• Incoming verification and storage handling checklist

Automotive Tier 2

Automotive Tier 2 Cooling Module Seal Qualification

Challenge

A Tier 2 module supplier needed a repeatable elastomer part with quality-system records suitable for downstream customer approval.

RubberQ Response

RubberQ aligned material choice, tooling assessment, dimensional control, and PPAP-oriented documentation under its IATF 16949 process system.

Project Records

• Drawing-based tolerance and inspection plan
• PPAP-oriented documentation scope
• Material batch and process traceability flow

Bring us the drawing, media, temperature window, and annual volume.

RubberQ will map the material path and confirm the practical next step before quotation.
