Analysing the cell Structures and the mechanical short and long term properties of rubber Profiles

Influence of Vulcanization Parameters on the Structure and mechanical Properties of expanded EPDM

In the quality control of foamed rubber profiles, mechanical long-term tests are required to determine the degree of cross-linking. The long test duration results in a production risk for the manufacturer. more...

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...
