PUR FOAM HAS EXTENSIVE USES AND IS AN INTEGRAL PART OF DAILY LIFE.
PUR foams are synthetics. The key materials for production are liquid raw materials, which are synthesised from petroleum by means of a step-by-step, complex process into the main raw materials diisocyanate and polyol. The production process involves polymerisation or, to be more precise, chemical polyaddition.
Thanks to the use of a wide range of additives, the properties of the foam can be customised to meet the specific needs of our customers.
PUR foam has diverse properties. The following diagram shows a selection:
Our standard foams are highly air permeable and have a regular cell structure. Conventional foams are available with densities of 15 to 110 kg/m³ and hardnesses of 1.0 to 25.0 kPa. They are used for upholstered furniture, mattresses, sports, shoes and automotive interiors.
HIGH RESILIENT (HR) FOAMS
High resilient (HR) foams stand out for their particularly durable properties in the comfort segment. The densities range from 23 to 60 kg/m³ with hardnesses of 1.3 to 12.0 kPa. They are mainly used for upholstered furniture and mattresses.
Comfort foams (Combustion Modified High Resilient) comply not only with standard flammability safety requirements, but also other strict rules on public fire safety. Their uses range from public buildings, cinemas and theatres to cable cars, trains and trams.
Viscoelastic (memory) foams are open-cell flexible foams that fully develop their temperature-sensitive properties upon exposure to body warmth.
Viscoelastic foams mould themselves to the shape of the human body and relieve pressure.
Technical foams comprise a range of polyetherpolyol-based and polyesterpolyol-based foams. They have a wide range of uses: automotive, aircraft seats, industrial applications and functional packaging.
Composite or recycled foam enables the production of foams with an extremely high density.
The densities range from 60 to 700 kg/m³.
These foams are chiefly used in the automotive, acoustics and leisure and sports segments.
