Bei Elastomeren wird über die Beschichtung vor allem der Reibungskoeffizient verringert, was auch zu einer stärkeren Vereinzelung der Dichtungen führt.  Bild: Trelleborg

Beschichtungsverfahren für medizintechnische Dichtungen

Just a thin coat

Big results can be obtained with the thinnest of coatings. At the nano-scale, an innovative surface treatment from Trelleborg Sealing Solutions significantly improves friction and stick-slip properties of elastomer seals while having little or no effect on the performance of the compounds the seals are made from. more...

Laser Flash Analysis

Determination of the Thermal Diffusivity and Thermal Conductivity on Rubbers by means of Light/Laser Flash Analysis (LFA)

In order to get information about the heat transfer in materials, researchers and engineers have to select from a variety of test methods the most suitable one to characterize the thermophysical properties of substances and configurations of interest. For many material classes including polymers, the flash technique is an ideal choice to master these tasks. […] more...

Rubber

Aging and Resistance Studies of Elastomeric Materials

During their application, elastomeric materials are exposed to different environmental influences, which can be the reason for material changes known as „ageing“. Therefore, beside the general facts of ageing, this publication gives a short overview of a literature study regarding artificial ageing investigations. more...
