Sponge EPDM Profiles
Cellular sponge EPDM rubber profiles, with a spongy structure for elastic seals with reduced compression force and excellent elastic memory. Ideal for joinery, facades and applications where sealing pressure must be limited.
Technical Specifications
Indicative values for sponge EPDM profiles. Exact parameters are determined according to the cross-section and the required compression force.

Damping and sealing for covers and panels with reduced closing pressure.
Frequently Asked Questions
What is sponge (cellular) EPDM rubber?
It is a profile with a spongy cellular structure, obtained through an expansion process of the EPDM material, which provides elastic sealing at a much lower compression force than compact rubber.
How do I choose the right density for a sponge profile?
The density (0.3–0.6 g/cm³) and the degree of compression (20–60%) are determined according to the available sealing force and the desired elastic recovery — we recommend the right solution based on your application.
Do sponge EPDM profiles resist outdoor conditions?
Yes — just like compact EPDM, sponge EPDM profiles have excellent resistance to ozone and UV, making them suitable for outdoor seals.
What information should I send for a sponge profile quote?
The technical drawing of the cross-section or a physical sample, the required length and the compression force available in your application.
