Silicone Sponge Seals & Thermal Pads for Automotive and EV

Closed-cell silicone sponge seals housings with very little closing force, and it keeps that seal through heat, cold and vibration where foams and EPDM sponge break down.

Centroid supplies silicone sponge cords, tubes, sheets and moulded sections for automotive gaskets, vibration dampers and weatherstrips, plus thermal pads for ECUs, sensors and power electronics.

In EV battery packs, silicone sponge and thermal pads absorb cell swelling, damp vibration and move heat, with flame-retardant grades for safety.

What Automotive & EV buyers need

  • Low closure force sealing for lightweight housings
  • Compression-set resistance across temperature extremes
  • Vibration damping for electronics and lighting
  • Flame-retardant grades for battery packs
  • Thermal management for ECUs and power modules

Standards commonly specified

  • SAE J20
  • IATF 16949 supply chain
  • UL 94 (EV components)
  • RoHS
  • REACH

Compliance varies by product and compound. Ask us for the certificates and test reports for your part.

Frequently asked questions

Why silicone sponge instead of EPDM sponge?

Silicone sponge keeps its resilience over a wider temperature range and resists compression set, so seals stay effective longer.

Are your sponge products used in EV batteries?

Yes. Silicone sponge sheets and thermal pads are used as compression pads, seals and thermal interfaces in battery modules.

Can you supply moulded sponge parts?

Yes. We supply extruded cords and tubes, sheets, and moulded sponge sections to drawing.

Need a custom part for automotive & ev?

Send a drawing or sample and our engineers will recommend a compound and quote.
