Coping with Temperature Variation on the Surface of Dies - Smart Polymer Chemistry

| November 30, 2017

Overcoming variations in die temperature to provide an evenly distributed protective coating has been a long standing and challenging problem in high pressure die casting. Traditionally the ability of a die casting lubricant to form a protective die coating when exposed to hot areas of the die and not build in cooler less demanding areas could only be achieved with a modified spray application system. The inert nature of die casting lubricant components requires the materials to respond the same regardless of their environment. A lubricant must be chemically reactive to adapt to thermal variations on the die surface.

Euric unveils Waste & chemicals brochure

Article | May 2, 2021

Recyclers have developed state-of-art separation techniques to safely treat a wide diversity of waste streams and recover valuable materials, hence directly contributing to the circular economy. The Brochure published by Euric on ‘Sound Management of Waste & Chemicals Requirements’ highlights the main issues derived from the lack of interface between chemicals, product and waste legislation, and identifies simple solutions to boost the transition towards a more circular economy. Christer Forsgren, Chair of the Euric’s Waste & Chemicals Task Force, Environmental & Technical Director at Stena Metall AB (Sweden), and Adjunct Professor in Industrial Material Recycling at Chalmers Technical University in Gothenburg, emphasized the key role that Europe’s recycling industry plays by reducing Europe’s dependency on primary materials and by saving massive amounts of CO2 and energy.

Chemical Recycling of Plastic – Waste No More?

Article | May 2, 2021

When it comes to the circular economy transition, plastics recycling is as much of a challenge as an opportunity. Today, around 25.8 million tons of plastic waste are generated in Europe every year, with less than 30 percent of it getting collected for recycling. This is a huge loss of valuable resources to the economy, and with a huge cost to the environment. Could chemical recycling be part of the ultimate solution, making the plastics value chain more circular whilst providing a profitable new industry branch.

Why chemical characterization is the best way to assess patient risk

Article | May 2, 2021

Everyone is very familiar with the phrase when buying a house: All that really matters are three things - location, location, and location. This same principle applies to extractables and leachables chemistry analysis – the three things that truly matter are identification, identification, and identification. The greatest growth in the past ten years in demonstrating the safety of medical devices and container closure systems for drugs has been using analytical chemistry to determine what chemicals can leach from the device and what the patient is exposed to during its intended use.
