Polyurethane wheels and casters from Blickle for every application

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.

Polyurethane materials – overview of treads

Blickle Extrathane®

  • hard reaction-injected polyurethane elastomer based on polyesterpolyol, diisocyanate and diol
  • provides a number of different benefits (e.g. high load capacity, floor surface preservation, operational comfort), making it suitable for a variety of applications
  • low rolling resistance
  • resistant to a wide range of aggressive substances, with the exception of hot water or hot air with a high humidity level
  • antistatic version available
  • main applications: Intralogistics, machine and systems engineering, mobile devices and equipment

Blickle Softhane®

Are polyurethane wheels good for outdoor use?

Polyurethane wheels are suitable for outdoor use. They have a high wear resistance and are UV-resistant. They can even be driven on uneven floors without any problems.

How to clean polyurethane wheels?

Polyurethane wheels and casters can be cleaned with various cleaners such as benzine, machine cleaner, or even isopropanol (very small amounts).

Are polyurethane wheels soft?

Polyurethane wheels are available in different degrees of hardness. These can also be customised according to customer requirements. All types of pu wheels have an excellent elasticity, resulting in very low rolling resistance.

How to dye polyurethane wheels?

PU wheels can only be coloured during production, after the chemical reaction of the individual components this is no longer possible.

Do polyurethane wheels mark the floor?

Polyurethane wheels are non-marking and therefore leave no stains or streaks on the floor.

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.
