The Grade Series

Series 100, ester grades

Injection molding, extrusion and blow molding grades with a high mechanical strength. In extrusion applications, there is no crystallization of the melt with grades in this series even when the extruder has been in service for a long period of time. Used primarily for articles subject to wear, such as castors, shoe heels, pneumatic hoses and bellows.

Series 200, ester grades

Blow film and coating grades which can be used to manufacture consumer goods for food contact.

Series 300, ester grades

Injection molding and extrusion grades offering high mechanical strength together with improved hydrolysis resistance and low-temperature flexibility. Low swelling values in oils, greases and solvents.

Series 400, special ester grades

This series offers a number of special properties thanks to the use of special raw materials and ancillary materials. Compared with the 100 and 300 series of ester grades, the individual materials display improved:

These injection molding grades are used first and foremost in functional engineering components for automotive, mechanical and plant engineering.

Series 500, ether/ester grades

Ether/ester grades that combine the advantages of both classes of raw material at low cost. These are used in applications subject to mechanical stressing with a simultaneous risk of damage through micro-organisms. Fields of application include extrusion caoting, seals, injection molded engineering components and watch starps.

Series 600, ether grades

The grades in the 600 series can be used as a lower-cost solution for applications that require the hydrolysis and microbe resistance of the 900 series but not such high-level mechanical properties. Potential applications include fire extinguisher hoses, shoe soles and rigid/flexible combinations.

Series 700, carbonate grades

The grades in this series have been specially developed for particular applications and have been successfully used in these applications for many years. They display good resistance to microbes and hydrolysis, experience less swelling in water than ether grades and offer a level of mechanical properties comparable to ester grades.

Series W8000, aliphatic

The new Desmopan® product line based on an aliphatic isocyanate. In addition to possessing the familiar properties of TPUs, these products do not yellow under the action of UV light. They additionally offer a particularly high resilience and "snappiness". This is why these grades are particularly suitable for colored applications in automotive engineering and the sport and leisure sectors.

Series 900, ether grades

Products offering very good hydrolysis and microbe resistance. Their excellent low-temperature flexibility constitutes a further characteristic feature. The 900 grade series is used inter alia in applications where good flexibility or impact strength is required at very low temperatures.
