This speaks for polurethane

Special properties of polyurethane

Special properties can also be achieved by combining two polyurethane formulations in one PUR component. For example, we combine different hardnesses and even different systems (compact and foamed PUR) to achieve the best possible damping paired with enormous wear resistance.

We process all polyurethane systems (MDI, TDI and NDI isocyanates as well as polyester, polyether and polycarbonate systems) in the hardness range from 40 ShoreA to 75 ShoreD – this also includes Vulkollan® * D15. By processing on the most modern multi-component casting machines, we also guarantee the highest and consistent quality.

We have over 150 different recipes that we successfully market under the brand names TECTHAN and THELAN. Our main advantage is that we do not purchase finished polyurethane systems, but instead rely on self-developed polyurethane formulations, which were developed through close and long-term cooperation with our customers. As a result, we have the opportunity for improvement ourselves and can react quickly and flexibly and offer a solution.

Icon AbriebfestigkeitFor applications where the least possible abrasion is required, e.g. for wear protection plates or support rings, we offer a special polyurethane formulation with abrasion <20mm³ according to ISO4649 with almost the same mechanical properties, e.g. Tear resistance.

One of the most outstanding properties of polyurethane is the enormous elastic extensibility. With a polyurethane formulation with a hardness of 85ShA, the polyurethane component can theoretically be stretched more than 5 times its original length and then returns to its original shape.

In dynamic applications it is important that a polyurethane component damaged by a crack has the highest possible tear resistance so that the usability is not impaired. Here we offer various polyurethane formulations that achieve tear strength of over 100N / mm according to ISO34-1.

In applications such as processing or screening technology, polyurethane components often come into contact with a wide variety of microbes. These microbes quickly attack a standard polyurethane system and ensure that the mechanical properties decrease very quickly and the polyurethane component fails in use.

We have various solutions to this problem so that microbes cannot harm your polyurethane components.

Hydrolysis is the splitting of chemical compounds by water. If the polyurethane component comes into direct contact with water or is permanently exposed to particularly high humidity, the mechanical properties of standard polyurethane systems degrade quickly and the polyurethane component becomes soft and brittle. Systems decide.

We offer various solutions for this application.

Standard polyurethanes, like all plastics, are insulators and therefore unable to dissipate voltages. However, we offer special polyurethane formulations with antistatic properties or even as electrically conductive versions. These are required for special applications of rolls and rollers and are successfully used in the area of sheet steel production for roller coating.

Hysteresis means that a portion of the energy introduced into the polyurethane component leads to heating due to internal friction. This high dynamic load can cause components from standard polyurethane systems to melt.

We offer polyurethane formulations that have been specially developed for this purpose, such as polyurethane springs in high-frequency applications.

Very often, polyurethane components are used in areas where they are constantly exposed to chemical media that would decompose a standard polyurethane very quickly. Areas of application for this are e.g. concrete processing, processing technology, mills, …

We have various polyurethane formulations in our portfolio for this challenge. For the right solution, we need as much information as possible about the application and the medium, such as temperature, pH value, etc.

Because of our own R&D office, we have the option, for example, to chemically examine your grinding slurry and choose the ideal polyurethane recipe or develop a new polyurethane recipe.

The cornerstone of the POLYTEC GROUP was laid by the manufacture of finishers for snow grooming equipment (snow groomer). The usability of the polyurethane component at low temperatures is particularly important here, since the so-called finishers still have to be flexible at significantly below 0 ° C in order to create a perfect slope profile.

However, there are many other areas of application for polyurethane where good cold flexibility is required is, such as in screening and processing technology.

A particularly high temperature resistance is crucial for special applications. We have made a lot of developments and tests in this area. We currently have a polyurethane formulation with a temperature resistance of 150 ° C under load in use.

However, we are working very intensively in this area in order to drive the temperature resistance even higher.

How is polyurethane processed?

Polyurethane (PUR) consists of three raw materials; Polyol, isocyanate and a crosslinker. Other substances such as accelerators, catalysts and additives are used in the diverse polyurethane formulations. A polyaddition reaction creates a solid but elastic polyurethane (PUR) component from the liquid raw materials.

We process polyurethane using the low-pressure casting process and the high-pressure spraying process. Due to the unique situation that we, as POLYTEC INDUSTRIAL, both process polyurethane and manufacture casting systems for polyurethane processing, we always have a modern machine park with precise and reproducible processing parameters. A variety of factors influence the final quality of the finished polyurethane component. These factors are recorded and controlled. This is the only way to deliver consistently high quality.

We have great flexibility with the addition of additives and processing of a wide variety of polyurethane formulations on the most modernly equipped polyurethane casting machines, which are developed and built by our global sister company POLYTEC EMC ENGINEERING. All polyurethane casting systems are linked to the operational data acquisition, which enables us to achieve a very high and consistent quality, as we always have the essential parameters in view.


In the spray area, we offer a wide variety of polyurethane systems on four high-pressure systems. Our standard ranges from the polyurethane wear protection system to polyurea systems to the DIN / EN approved corrosion protection system. The mobile on-site coating rounds off the department’s offer.

In contrast to the rubber coating, the THELAN spray coating offers a seamless coating for your components.

The individual multi-component, mixing and dosing systems of our sister company POLYTEC EMC are excellently processed and configured to personal needs – whether pouring, spraying, gluing or foaming.

The operation is simple – you can dose faster and more precisely, mix more homogeneously and apply better.
