The transition period for the Elastomer Guideline published by the Umweltbundesamt (UBA), Germany’s federal environmental agency, for assessment of elastomers in contact with drinking water, ends on 31 December 2021. Sulphur cross-linked compounds currently in use in drinking water applications can no longer be used after that time. The German rubber compounder Kraiburg based in Waldkraiburg in Bavaria has succeeded in developing compounds that can be used in elastomer solutions for drinking water applications after that date.

Rubber/metal composites tend to fail prematurely due to loss of adhesion of the rubber to the metal substrate, when they are exposed to aggressive conditions such as marine environments. The aim of this work is to elucidate the adhesion failure mechanism by cathodic disbonding and anodic undermining tests using a commercial bonding system for bonded rubber/metal.

With the help of a virtual DoE different injection points (red crosses) are compared regarding injection pressure and air entrapments for an LSR pot cloth. While Design 15 and 43 have a high risk of undesired air bubbles, Design 33 combines a good filling behaviour with a low pressure demand. (Source: Sigma)

The German company Sigma Engineering GmbH from Aachen is presenting its Sigmasoft Virtual Molding software and the enclosed Autonomous Optimization technology at various exhibitions in spring 2019. The software helps to find the ideal configuration of part, mould and process in one calculation. The Autonomous Optimization and the included possibility to conduct virtual Design of Experiments (DoE) help the users to improve existing injection moulding tools and processes as well as to virtually test different configurations and innovative approaches.

Due to environmental and sustainability concerns, it is desirable to replace mineral oil with vegetable oils as processing aids and plasticizers in rubbers. In this paper the effect of four polymerized soybean oils of high viscosity on processing and physical properties of EPDM rubber in a standard sulfur-cured formulation is evaluated.

Due to the need for new fuels with a lower environmental impact – may it be either lowering the carbon dioxide, general greenhouse gas, NOx or particle emissions – the worldwide landscape of fuel compositions is currently drastically changing. While in Central Europe a specified fuel is predominant, the constitution of fuels might tend to vary more in most other countries. Researchers at Freudenberg Sealing Technologies have reviewed the impact of those compositions on the seal materials and the seals themselves.
