Physical properties
The physical properties of Hawiflex® polyurethane systems have been created for use under the most extreme conditions: High abrasion resistance with excellent tensile strength combined with maximum dynamic loading requirements. Our polyurethane-based Hawiflex® plastic extends service life many times over.
Temperature range
The properties of Hawiflex® polyurethane are naturally temperature-dependent. For dynamic loading, the temperature limit for our standard systems is approx. +80°C to ensure no material breaks and cracking. Brief peak loadings up to +120°C are possible and permitted. But our company also offers special formulations for permanent loads above +80°C. As the temperature decreases Hawiflex® polyurethane becomes less elastic, but applications up to -40°C are easily possible without the materials becoming brittle.
Chemical properties
Hawiflex® polyurethane offers an excellent resistance against oil and grease, petrol and different solvents. Hawiflex® polyurethane is not changed by weather effects such as sunlight, oxygen and ozone. We even offer standard products resistant to considerable hydrolytic and microbial attacks.
Acoustic properties
The sound-absorbing properties of Hawiflex® polyurethane are particularly apparent where bulk material is transported. Your staff will be delighted that noise levels are reduced by up to 50 %.
Hawiflex® polyurethane advantages for moulded parts or coatings:
- Resistant against cuts
