Silicone and EPDM sponge rubber
Exonel makes closed-cell silicone and EPDM sponge profiles, strips and gaskets that seal softly under low compression force. They suit mating faces that are uneven or lightly clamped, such as enclosure doors, luminaires and appliance panels.
Figures are indicative and are confirmed for your application before tooling.
Soft sealing where solid rubber cannot.
Low compression force
Closed-cell foam seals against uneven faces under light clamp load.
Closed cells
The cell structure resists water uptake, so it works for dust, draught and weather sealing.
Recovery
Springs back through repeated open and close cycles.
Silicone or EPDM sponge.
Silicone sponge
High and low temperature sealing with UV and weather stability.
EPDM sponge
Weather, ozone and water sealing at lower cost for outdoor use.
