The role of chemistry
External effects can damage the transport system, especially the wheels. Basically we distinguish between two types of adverse chemical influences:
- Contact with chemical substances in accordance with the regulations.
- Environmental influences of fluid or gas that prevail at the place of use.
Both these influences can adversely effect not only the overall performance of the castor or wheel, but also the individual components of the assembly, in the form of corrosion, surface changes, loss of strength, embrittlement and degradation of the lubricant properties. Castors that will be used in such problematic environments must have the suitability of their components such as housing, wheel hub, and tyres checked. Not only time in contact, the concentration of the aggressive chemical substances, but also the humidity and the temperature are factors that influence chemical resistance. The information in the following tables can be used as a guide. The values given are not valid for chemical mixtures.
+ conditional resistance
