Thermoplastic elastomers (TPEs) are an established alternative to vulcanised rubbers in sealing applications for non-pressurised water systems, such as drainage and sewerage, according to Kiwa NV.

In a paper presented at the DKT 2018 conference in Nuremberg, the Dutch firm explained how it is setting up a new evaluation guideline for ‘thermoplastic’ seals in drinking-water applications.

As a starting point, the Rijswijk-based company is using an evaluation guideline based on EN 681-2 with additional tests in which the anisotropic behaviour of TPEs is taken into account.

Zeon Corp. is seeking to enhance the long-term properties of hydrogenated nitrile rubber (HNBR) to meet increasing demands from the automotive and oil & gas industries. A particular focus is on peroxide-cured compounds, in which the use of metal oxides – typically 3-5phr of zinc oxide – is standard, set out a paper presented by Dana Stripe at the recent DKT 2018 conference in Nuremberg

Technical paper from Korean petrochemicals group shows how system can deliver high levels of catalytic activity & C3 conversion, controllable molecular weight distribution and optimised diene distribut

The tandem process has already improved the mixing process considerably. In the future, the machines will have to be further optimised with regard to dispersion, distribution, temperature control and process consistancy with improved economy…

DuPont has published a new white paper to explain how replacing metals with high-performance polymers can help make vehicles lighter with the added benefits of easier processing, integration of functions and lower costs. Taking weight out of the vehicle is also a key route to achieving those goals, but the question is — how best to reduce weight?,  the company said in a release about the new guide.

For years, the use of laser technology has been growing in all industrial sectors. At the request of numerous actors in the rubber and polymer injection industry, REP has worked with laser-specialized partner Laselec and developed a laser technology machine dedicated to the cleaning of industrial parts and injection and compression moulds.

Selecting a high-quality elastomer for critical applications, particularly medical devices, can be a challenge. Designers, engineers and managers must carefully evaluate a wide array of material properties and processing possibilities. In this white paper, Lubrizol company Vesta offers some helpful factual information on silicone rubber elastomers, their properties, fabrication methods and advantages.

All buildings and structures are subjected to ground vibration, or forcing frequencies, which can not be stopped but can be controlled. Trelleborg designs bearings to meet the performance specifications to do so…

Continuous Improvement has been around for decades. Building blocks of the concept began in the 1930s with Dr. Walter Shewhart of Bell Telephone Laboratories; followed by Dr. Joseph Juran, known for his Quality Control Handbook;then Dr.W.Edward Deming,famous for his 14 points of Total Quality Management (TQM).
