For sealing materials in contact with gases such as hydrogen, a consideration of gas permeability is of elementary importance for the assessment of safety, functionality and reliability. The aim of the presented study is to give an overview of the permeation behavior of thermoplastic vulcanizates (TPV) and ethylene-propylenediene rubber (EPDM) towards hydrogen under consideration of processing influences. A comparison of TPV and EPDM shows a differentiated permeation behavior.

At Medical Design & Manufacturing (MD&M) East, 11 – 13 June 2019, in New York City, Covestro presented its raw materials for the healthcare industry. The company showcased its Baymedix portfolio for skin-friendly adhesives, absorbent foams and waterborne coatings; and Dureflex and Platilon product portfolios for medical films.

Icynene-Lapolla has launched the Icynene X-Wall System, an all-in-one continuous insulation solution for the exterior envelope, that is said to provide long term energy efficiency and savings, protecting the structure from nature’s elements.

According to an article by M. Rigby, S. Park, et al., published in the international journal of science Nature 569, p. 546 – 550 (2019), the recovery of the stratospheric ozone layer relies on the continued decline in the atmospheric concentrations of ozone-depleting gases such as chlorofluorocarbons. The atmospheric concentration of trichlorofluoromethane (CFC-11), the second-most abundant chlorofluorocarbon, has declined substantially since the mid-1990s.

The German company Hennecke GmbH is well-known for providing polyurethane systems and technologies that are geared to meeting customer requirements in all conceivable applications. According to the company, this would not be possible without intensive and continuous research and development at the in-house Techcenter. This example from Nanostone Water GmbH demonstrates how a ceramic industrial filter with a polyurea coating was developed for serial production at the Techcenter in close cooperation with the customer.

Dow announced the recent completion of a project with customer Kraiburg Relastec GmbH & Co. KG to power a new running track exhibit at the Olympic Museum in Lausanne, Switzerland.

A BASF plastic additives package is helping to protect the roof at Incheon Airport’s Terminal 2, with thermoplastic polyolefin (TPO) sheets produced by Wonpoong Corporation in South Korea under the brand name SuperGuard.

LyondellBasell announced that Phu My Plastics Production JSC has chosen its Spheripol polypropylene (PP) process technology for a new 300,000 t/y PP plant in Vietnam.

Marine oil spill barriers, also known as oil containment booms, can last longer and keep oil spills under control even under intense sunlight, thanks to light stabilisers from BASF. The South Korean company Wonpoong Corporation is now using BASF’s Tinuvin range of plastic additives to increase the lifespan of oil containment booms, thereby reducing the maintenance costs and environmental impact.

Serinol and serinol derivatives are used in place of diphenyl guanidine as secondary accelerators for the vulcanization of compounds based on diene elastomers and silica as the filler. Kinetics of crosslinking are investigated and confirmed by performing vulcanization of an NR based compound in the absence of any filler. Serinol can be obtained glycerol transformed, by means of sustainable technologies into molecules suitable for the rubber world.
