Tommie Ibert, Development Engineer, tests the new advanced video extensometer that has been installed at the Nynas Rubber Compounding Lab in Nynäshamn.
The extensometer is a significant complement to the tensile testing machine, to monitor the true extension of the test sample, hence giving more detailed information on the tensile properties of the rubber material. This means you have optical mapping of the tensile behaviour from start until fracture, without any physical contact with the test specimen.
With the new equipment it is possible to show how different process oils affect the tensile properties which are important for the design of rubber materials used in the tyre and industrial rubber industries.
The environmental impact of tyres comes mainly from their usage, but also to quite some extent from the raw materials. Making more environmentally friendly tyres thus requires using more renewable and recyclable material.Read more about How to lower the ECO footprint of a tyre
2020 was a year like no other. Beyond the face masks, social distancing and working from home, the economy took a dive. These unprecedented events coincided with an ongoing restructuring of the refining industry, which will have a lasting effect on the production of tyres and rubber.Read more about Plasticizing rubber after Covid-19
