PUR foam: Versatile sound insulation for machines and vehicles
PUR foam (polyurethane foam) is a flexible and versatile material that offers excellent properties for technical sound insulation. Due to its structure and material properties, PUR foam is ideal for insulation and sound absorption in various industrial and technical applications.
Advantages of PUR foam
PUR foam is characterised by its high sound absorption, good thermal insulation and resistance to moisture and oil. These properties make it a preferred material for sound insulation in machines, vehicles and other applications. PUR foam is also lightweight and easy to process, which makes it particularly versatile.
Areas of application for PUR foam
- Machinery and vehicles: PUR foam is used in vehicles – including buses and rail vehicles – as well as in machinery to effectively reduce noise generated by engines, drives and mechanical components. Its sound-absorbing properties contribute to improving acoustic comfort.
- Heat pumps and building services: Heat pumps generate vibrations and noise during operation. PUR foam helps to efficiently dampen these, thereby minimising noise pollution in living and working environments.
- Medical technology: A quiet environment is essential in medical facilities. PUR foam is used here to absorb operating noises from devices and equipment, thus creating a pleasant atmosphere for patients and staff.
- Cabins/capsules and hoods: In industrial applications such as soundproof cabins, machine enclosures or under hoods, PUR foam effectively reduces noise emissions while protecting adjacent areas from sound transmission.
- Construction and agricultural machinery: These machines generate considerable noise due to their intensive use. PUR foam is used specifically to reduce noise pollution for operating personnel and the surrounding area.
- Room acoustics: PUR foam is also used in the field of room acoustics – for example in offices, studios and public buildings. Its sound-absorbing properties improve speech intelligibility and reduce reverberation times.
