Polyurethane foams
Open-cell foam
We always have PUR foams with a variety of densities, compression strengths, and cell structures in stock. This allows us to work with you to select the right material for your products.
Our standard product range also includes specialty types such as flame-retardant, biocompatible, cross-linked, antistatic, and electrically conductive materials.
An overview of PUR properties:
- Flexible & elastic with high resilience
- Shock-absorbing, vibration- & sound-damping
- Breathable & good liquid absorption
- Lightweight
Filter foam
Cold foam
Composite foam
Viscoelastic foam
Sponge foam
Polyester foams
Ester-based foam
Polyester foams stand out for their versatility & and reliable quality. Whether in the packaging industry or in technical applications, polyester foam adapts flexibly to your needs. Thanks to its structure, it remains effective even under heavy use.
Properties
- Regular cellular structure
- Shock-absorbing
- Suitable for high mechanical stress & chemical resistance
Polyether foams
Ether-based foam
In addition to their general advantages (high elasticity and open-cell structure), polyether foams also offer specific properties such as flame retardancy and antistatic treatment. They are also highly resistant to water, acids, and alkalis.
Properties
- Open-cell structures
- Elastic with high resilience
- Resistant to water, acids & alkalis
Good to Know: Technical Terms
All About PUR Foams
volumetric weight
- Density of the foam
- Measured in kilograms per cubic meter (kg/cbm)
- The higher the density, the more elastic the foam
compression hardness
- Foam density
- Measured in kilopascals (kPa)
- The higher the value, the harder the foam
cell structure
- Structure within the foam that forms during foaming
- Affects foam properties
Cell size
- Size of individual pores in the foam
- Measured in pores per inch (PPI)

Filter foam
High-tech for demanding applications
Filter foams are highly engineered foams with a uniform open-cell structure. The nearly complete opening of the pores in the foam through “reticulation” makes it resistant to soap, oils, and detergents, as well as water-resistant.
Filter foam is used for:
- Filter cartridges, such as dust, air, and water filters
- HVAC and ventilation technology
- Hi-Fi filters
- Packaging aids
Cold foam
HR foam
Cold foam, also known as “mattress foam,” derives its unique open-cell structure from its cold manufacturing process (unlike standard PUR foam). This manufacturing process makes it more elastic and denser than conventional PU foam. This gives it dimensional stability, durability & and point elasticity.
We would be happy to manufacture:
- Mattresses
- Upholstery
- Cut-to-size pieces
Composite foam
Recycled & high-strength foam
At Polyform, some of the material scraps from production are shredded by type and prepared for recycling. These foam flakes are bonded and compressed externally, turning these scraps into composite foam. This foam is then reused at Polyform to manufacture new products.
Composite foam is ideal
- for sound, noise, & and thermal insulation
- as packaging material
- as rigid edge protection for sensitive products
memory foam
Viscoelastic foam
Viscoelastic foam reacts to heat & and has a “shape memory.” It provides even pressure distribution, offering excellent support.
That is why we often use viscoelastic foam for orthopedic aids and positioning aids in the medical and rehabilitation sectors.
- Good pressure relief = softer
- Thermoplastic = warmer
- Slower recovery
Sponge foams
PUR Foam for Care & Cleaning
We offer a wide range of sponge material qualities. To see the versatile applications of our sponge foams, please visit our dedicated sponge page!
Our sponges are ideal for many applications, such as
- Skilled trades
- Car care
- Industry
