Abrasion is the volumetric loss of material caused by friction. Abrasion of an elastomer is measured in mmÂ³ and determined by moving rubber a specified distance across a rough surface with a defined contact pressure. Abrasion causes the cylinder covers of rubber cylinders to wear away. It can be resolved to a certain degree by repolishing the rubber cylinders.
The aging resistance of a material is its capacity to barely change over the course of time. The value does not take effects such as chemicals or forces on the material into account. Since there are a great number of factors which influence aging, the wear and tear of rubber cylinders and plastic cylinders, it is necessary to know their ambient conditions precisely in order to select the best material for the cylinder covers.
