Tribometrical results for the functional performance capability of chemicals

Durability, robustness, adhesive strength and wear resistance - these are only some of the many properties required for chemicals

No matter if we are talking about the wear of plastic plain bearings, the friction-reducing effect of lubricant additives, the adhesive strength of surface coatings or the squeaking noise of plastic components in relative movement: Many chemicals (such as additives, coatings, lacquers and plastics) are exposed to tribological stresses when used. However, the effects mentioned above are only a minor part of what needs to be taken into account when it comes to ideal product functionality. Our precise, straightforward and quick methods for testing the functional performance capability of chemicals create the prerequisites that our customers need for optimising, specifying and verifying their products.
