PP castors

PP (Polypropylene) is a rigid plastic and was invented in the 1950s. At first glance, the material resembles nylon (PA6), but upon closer inspection, there are differences in both properties and functionality. PP and PA6 are often mentioned together precisely because the materials resemble each other.



Mats elaborates

As mentioned, PP and PA6 resemble each other, but what are the actual differences and which one is right for me? Our technical sales representative, Mats Persson, has written in more detail about the differences between the materials.

PP wheels have a high load-bearing capacity and good resistance to water and moisture. Since PP is a rigid plastic, the wheel rolls easily but may encounter issues on uneven and dirty surfaces where gravel and other objects can get trapped between the tread and the surface, potentially causing scratches. PP is "non-marking" and does not leave marks or oil stains on floors. However, PP lacks resistance to UV light, and for applications exposing the wheel to UV, other materials are recommended. PP also doesn't handle cold temperatures well and becomes brittle, resulting in decreased weight tolerance.

From an environmental perspective, PP is excellent as it is completely recyclable, and all natural waste in production is recycled, which has been the case for several years now. Swede-Wheel currently offers a wide range of recycled PP wheels up to 125mm.


Slideability is a term that has gained significance in the industrial and logistics sectors. The attribute refers to the ability of a cart or trolley to smoothly slide into a tight space with its wheels. The concept emerged as a result of feedback from end-users who desired greater maneuverability.

Test center

The testing center is a significant part of our operations. It plays a key role in ensuring the quality of our products and provides valuable opportunities to acquire in-depth technical knowledge.

Testing is particularly useful when it comes to understanding materials. It provides a forum for objectively discussing the properties that materials possess or lack. The knowledge generated in the testing center is utilized by the development department, which then translates it into production processes.
