Silicone Foam Solutions
Four processes — calendering, extrusion, molding, die-cutting — for EV battery seals, thermal interface pads, gasketing and vibration damping.
Four Processes. One Material. Any Geometry.
Calendered sheet, extruded profile, molded block, or precision die-cut gasket — we run all four silicone foam processes in-house, with custom density, hardness and flame rating.
- Calendered sheet 0.5 – 30 mm thick
- Extruded profiles & cord
- Molded foam parts (complex geometry)
- Precision die-cutting & kiss-cutting
- UL94 V-0 flame retardant grades

FAQ
Frequently Asked Questions
What density do I need?
Gap filling and cushioning: 0.25-0.40. Sealing: 0.40-0.60. Structural support: 0.60+. Tell us the compression force and seal gap — we calculate the right density.
Can the foam come with adhesive backing?
Yes — PSA (acrylic or silicone adhesive) lamination is available on sheets and die-cut parts, with liner.
Which flame rating?
UL94 V-0 and HF-1 grades available; standard grades pass automotive interior burn tests.
Silicone foam vs PORON / polyurethane foam?
Silicone foam survives temperatures and outdoor exposure that destroy PU/poron; choose silicone above 120°C continuous, outdoors, or where UL94 is required.
What is the MOQ?
Sheets: from one roll. Die-cut gaskets: no MOQ for prototyping; volume pricing from 1,000 pcs.
