The 62nd annual Polyurethanes Technical Conference, organized by the Center for the Polyurethanes Industry (CPI) of the American Chemistry Council (ACC), was held in Orlando, FL, USA, from 7 – 9 October 2019. More than 800 experts attended the three-day event, which once again highlighted the impact of polyurethanes on the world today. One of the conference’s key topics this year was sustainability and how the industry promotes it for the future.
K 2019 has closed its doors on 23 October 2019 after eight exciting days in Düsseldorf, Germany. 3,330 exhibitors (2016: 3,285) from 63 nations proved impressively: plastics continue to be an innovative, indispensable material. But they also underscored the necessity of having operational circular economies along the complete material chain and to this end already presented numerous concrete solutions.
The specialist exhibitions and conferences organiser Smarter Shows announced that Foam Expo Europe 2019, Europe’s largest trade fair dedicated to the technical foam industry, expanded its scope this year to welcome more participants from related sectors and recorded a significant increase in attendee numbers. Running in parallel with the event, Composites Europe, organised by Reed Exhibitions, offered synergies for the joint application industries such as automotive, aviation, the construction sector and the sports and leisure industry.
The AVK – Industrievereinigung Verstärkte Kunststoffe has published the 2019 market report for glass fibre reinforced plastics (GRP). Total GRP production is unchanged compared to 2018 at a total volume of 1.141 million t in 2019. The GRP market is expected to stagnate in 2019 after six consecutive years of growth. Germany remains the largest manufacturer of GRP with 225,000 t. Some growth is observed in thermoplastic processes, SMC/BMC and pultrusion. The present article is a summary of the full market report, which can be downloaded free at AVK’s website.
The year 2020 will be an anniversary year in three respects for the IKV – Institute for Plastics Processing in Industry and Craft at RWTH Aachen University: The RWTH Aachen University celebrates its 150th anniversary, IKV will celebrate its 70th birthday and it will be the 30th time it stages the International Colloquium Plastics Technology – on 11 – 12 March 2020 in the Eurogress Aachen. The day before the colloquium, on 10 March 2020, IKV will mark its anniversary by holding the International Symposium on Plastics Technology in the VIP area of the Tivoli soccer stadium. While the colloquium will present the broad range of IKV research and will target primarily the plastics industry with its practice-oriented research, the symposium will feature papers from scientists from 14 countries, and aims to arouse lively discussion between scientists and industry.
During the course of the CPI 2019 conference in Orlando, FL, PU Magazine had the chance to talk to Lee Salamone, Senior Director of the Center for the Polyurethanes Industry (CPI), Ernest Wysong, 2019 Conference Committee Chair, and Stephen Wieroniey, Director of the Sustainability Committee (CPI), about the event, current activities of the Center and future developments.
Recently, PU Magazine had the chance to talk with Alex Ehsani, Global Sales Director and Didier Grillot, General Manager EMEA of Isochem Group about the company, the main drivers and development of the industry, and how the discussions about sustainability and circular economy influence the business.
PU Magazine had the chance to talk with Navin Pydugadu, Senior Vice President at Universal Polymers Corporation about the company, the reasons behind recent mergers and acquisitions, as well as the development and outlook in the spray polyurethane foam industry.
Using spray foam insulation is a widely accepted method of insulating residential and commercial properties. Spray foam provides superior insulation, meets the demand for homes and buildings to be more energy efficient, and complies with new building codes requiring tighter, more energy efficient standards. Spray foam is made by combining two liquid chemicals; an isocyanate (A) and a polyol resin (B). Once these chemicals are mixed they are sprayed onto a substrate. Mixing these two chemicals creates an instantaneous chemical reaction. The two liquids, when mixed quickly, typically expand between 10 – 50 times in size and fully cure to the touch within a few seconds, resulting in the final spray foam product. Spray foam is manufactured on-site at the time of application, whereas most other building products – such as drywall, fiberglass insulation, oriented strand board (OSB), roof tiles, lumber and duct work – are manufactured in a factory and delivered to the job site. This allows for the materials to be spray applied as a liquid, allowing it to better insulate by completely expanding to fill gaps, cavities, around pipes, wires, in tight spaces, etc. Since it is manufactured on-site, having the proper controls in place to ensure it is manufactured correctly is important.
Representing more than 50 % of all blowing agents used in the PU and PIR industry, pentanes are the most common ones today. Haltermann Carless has the unique position in offering all three isomers. The pure pentanes and binary blends are more commonly used. Blends of all three isomers are rare and not described in literature. However, ternary blends may have advantages for insulation board manufacturing that have been missed so far. A basic experimental set-up was created to further investigate this idea. For the experiments, a standard PIR formulation was used to compare the performance of the pentane blends. The experiments were planned and the results were evaluated with the help of a design of experiment software.
In response to the global need for low global warming potential (GWP) and sustainable blowing agents, The Chemours Company has developed and commercialized Opteon 1100 and Opteon 1150. These hydrofluoroolefins (HFOs) demonstrate a wide range of attributes to spray polyurethane foam and construction insulation products. Spray foams are often installed throughout the year, and, in many regions, low winter temperatures present a challenge to installing spray foams. Many manufacturers specify a minimum substrate temperature to avoid installation issues that may include: reduced reactivity and dripping, reduced foam expansion and loss of yield, friability, adhesion failure and stud line cracking. In this publication, we will demonstrate how Opteon 1100 and Opteon 1150 can be leveraged to provide superior low temperature processing latitude in next-generation polyurethane foam products.
