Lean management – Methods and principles at Bäumer

Successful companies work hard every day to refine their own quality standards and improve quality, costs and delivery times for their customers. In order to meet this challenge every day, all the gears of the production process must always work together in harmony. These seamless processes are the key prerequisite for the creation of an outstanding product range, said the Freudenberg-based German company Albrecht Bäumer GmbH & Co. KG.

Corona: Crisis or chance for the PU industry? – Interview with the CPI leaders, Lee Salamone and Stephen Wieroniey.

Corona is putting a big spanner in the works for all of us this year. Many events had to be postponed due to the pandemic, including one of the industry's most important meet-ups - the annual Polyurethane Technical Conference that would have been in its 63rd edition this year. Organized by the Center for the Polyurethane Industry (CPI) of the American Chemical Council (ACC), the conference plus exhibition is the place where the industry meets, exchanges ideas, networks and, of course, learns about the latest innovations. This year, three days of online discussion panels were held on topics such as spray foam research, sustainability and the annual Global Regulatory Roundtable. Following the mini-conference, PU Magazine spoke with CPI’s leadership team, Lee Salamone, Senior Director, and Stephen Wieroniey, Director, about the current crisis situation and how nevertheless CPI continues to support its members and the industry as a whole.

Dry demoulding – practical demonstration of a mould coating with long service life

Sustainable thinking and acting is a constant driver of innovation in the polyurethane processing industry and is inherently applied in the development and implementation of future-oriented material and process technologies. Understandably, new technologies can succeed when they do not represent a step backwards in terms of robustness, flexibility and cost-effectiveness. In a German IGF cooperation (Industrial Collective Research) project at the Institute for Plastics Processing (IKV), Aachen, and the Fraunhofer Institute for Manufacturing Technology and Advanced Materials (IFAM), Bremen, the pilot plant readiness of a permanent release coating on a steel mould has now been demonstrated by consecutively demoulding more than 1,200 PU parts at constant low forces.

Catalyst solutions for stable polyol resin blends

Traditional and non-traditional amine-based urethane catalysts were evaluated for storage stability in polyol blends that use new low global warming potential (GWP) blowing agents, namely 1233zd(E) and 1336mzz(Z). Foam profiles were used to monitor each polyol blend throughout a defined storage time and temperature. As expected, molecular structure is a major factor in stability with halogenated olefin blowing agents, with traditional, unhindered amines degrading over time and blocked, hindered, or electronically deactivated amines providing stability.

Low emissions from polyurethane foaming materials

As automotive OEM requirements continue to focus on improving the indoor air quality of the vehicle and as the industry continues to face high environmental pressure to comply with low volatile organic compounds (VOC) and aldehyde emissions, raw material suppliers and polyurethane converters have had to come up with new product offerings to meet these requirements. Wanhua Chemical’s experience in sustainable development from theory to practice provides new alternatives to the value-chain. This paper primarily focuses on the sources of aldehydes in polyurethane raw materials and additives. Suggested improvements of aldehyde emissions are proposed from the perspective of improving the quality of the base polyether polyol, the selection of additives, and the aldehyde scavenger. Moreover, the impact of foam aging on aldehyde forming under the conditions of light, heat and oxygen is also discussed in this article.
