Sylomer® SR 42
Sylomer SR 42 is a mixed-cell polyurethane vibration isolation material from Getzner Werkstoffe, coloured pink. It isolates structure-borne noise and vibration in building, rail, and industrial applications where static loads remain at or below 0.042 N/mm2, delivering low natural frequencies and a long service life.

Applications
Sylomer SR 42 suits lightly loaded isolation situations such as under lightweight machinery, residential floating floors, and rail track-bed systems where static pressures stay below 0.042 N/mm2. It is available as rolls, stripes, and custom-stamped parts.
Standards and compliance
Flammability rated Class E to EN ISO 11925-2 and EN 13501-1. Material properties tested to DIN 53513, EN ISO 8307, EN ISO 3386-1, EN ISO 1856, DIN ISO 1827, EN ISO 527-3/5/100, DIN IEC 60093, and DIN EN 12664.
Frequently asked questions
What load range is Sylomer SR 42 designed for?
The static load range is up to 0.042 N/mm2. The operating load range, including dynamic loads, extends to 0.057 N/mm2, and short-term peaks are tolerated up to 2 N/mm2.
What thicknesses and formats are available as standard stock?
Standard stock is available in 12.5 mm (SR 42-12) and 25 mm (SR 42-25) thickness, supplied as rolls 1.5 m wide by 5.0 m long or stripes up to 1.5 m wide. Other dimensions and moulded parts are available on request.
What is the flammability classification of Sylomer SR 42?
Sylomer SR 42 is classified as Class E under EN ISO 11925-2 and EN 13501-1, meaning it is normally flammable.
