PU wheels and PU castors - abraison resistant and durable

The right tread for every application. Extrathane®, Softhane®, Besthane®, Besthane® Soft, Vulkollan®

Blickle has developed four different polyurethane types, tailor-made for different applications. Comprehensive expertise from decades of experience has been put into the Extrathane®, Softhane®, Besthane® and Besthane® Soft treads. This range is complemented by wheels made out of the equally high-quality polyurethane material Vulkollan®. This selection means that Blickle’s standard range has the right solution for almost any application. Special polyurethanes for high dynamic and mechanical loads as well as conductive and optimised rolling resistance versions round out the product range. All treads have a consistently high quality level, wear-resistance and resilience.

Our expertise: polyurethane research and development

The formula of the polyurethane material and how it is processed are the main factors affecting the quality of the end product. They have a significant impact on tread and tyre hardness, rebound resilience, abrasion resistance, load capacity, rolling resistance and low-temperature flexibility. That’s why Blickle has really got to grips with the material polyurethane. Our developers use the latest methods and keep close relationships with established scientific institutions to improve existing formulas and designs every day and keep our ideas moving. In addition to the properties of different polyurethane elastomers, the manner in which they adhere to the wheel centre also plays a significant role in the quality of the product. That’s why Blickle puts wheels and their treads through extensive testing as early as the development phase. This guarantees a consistently high level of quality. In addition to using cutting edge techniques like linear and non-linear FEM, Blickle’s engineers have a wide variety of test equipment in their laboratories. That is just one of the reasons why Blickle was the first German wheel and castor manufacturer to be DIN EN ISO 9001 certified in the year 1994.
