- Also known as PU or PUR foam
- Open cell -> water absorption
- Ester density: approx. 20 - 60 kg/m³
- Ester-based filter foams (air filtration) from approx. PPI 10 to PPI 100
- Ether-based density: approx. 17 - 50 kg/m³
- Ether-based filter foams (water filtration) from approx. PPI 10 to PPI 45
- PUR ether and ester foams with flame-retardant finish (MVSS 302, UL 94)
- PUR prepolymer qualities with extremely high tear resistance
- Compression hardness: approx. 2.5 kPa to 6 kPa
- Environmental compatibility: contain no CFC or HCFC (ZPU partly Ökotex 100)
- Max. Dimensions approx. 2,000 x 1,200 x 1,000 mm
- Temperature resistance from approx. -40 to + 110 °C

Ester-Schaumstoffe
- Very regular cell structure
- Good shock absorption thanks to high strength
- good UV resistance
- High resistance to oils, greases and organic solvents
- generally not lightfast (artificial and natural) --> yellowing of the foam, which has no influence on the physical properties
- physiologically harmless
- MVSS 302 and UL94 listed qualities also available
Ether-Schaumstoffe
- High elasticity with pronounced resilience
- Extremely soft to very hard compression hardnesses
- Good load-bearing capacity
- High resistance to water and aqueous liquids (hydrolysis resistance)
- Good resistance to acids and alkalis
- generally not lightfast (artificial and natural) --> yellowing of the foam, which has no influence on the physical properties
- physiologically harmless
- MVSS 302 listed qualities also available
- Antistatic properties
