Our material Hawiflex® polyurethane

The manufacture of low-wear polyurethane can rightly be claimed to be an art. We have developed the plastic to such an extent that we can provide it as a finished moulded part in various hardnesses. The properties profile of Hawiflex® polyurethane enables use anywhere where high abrasion is to be expected or dynamic loads lead to extreme stresses.

Our polyurethane-based Hawiflex® plastic extends service life many times over. Special hot-casting processes and an automated production allow us to produce a continuous properties profile.

With nearly 50 years of experience in high-performance elastomers, we can today offer a large variety of special formulations tailored to meet your requirements. This is achieved by special measures, such as the specific introduction of additives into our formulations of the initial raw materials. Our permanently further developed “intelligent materials construction kit system” offers designers and engineers solutions for small and medium-sized production runs in mechanical engineering.

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 %.

Fields of application for Hawiflex® polyurethane

The PU technology for wear protection and corrosion protection

After introducing the original brand Hawiflex® over 60 years ago, habermann materials set the scene for wear-reducing polyurethane technologies for use in moulded parts and coatings that are primarily used where a long service life and tremendous wear resistance are called for.

Hawiflex® polyurethane convinces due to its excellent resistance against abrasion and wear, oil and chemicals and has consequently proven itself time and time again. Competitors have often tried to emulate the brand but the company managed to further extend its technological advantage and to continuously secure its position as the market leader. Today, Hawiflex® polyurethane products of Habermann materials are successfully used by many industries and in nearly every industrial application and offer a clear cost structure as well as a considerable advantage.

And to ensure that you always have an advantage, we have at all times provided our planning and production from the same production site in Witten. We can thus guaranty that all our products are “Made in Germany”. Also those individually developed together with our clients.
