Toll manufacturing of speciality prepolymers at Third Coast – Interview with Steven English, Commercial and Marketing Vice President, Third Coast International

About one year ago, Third Coast successfully started its prepolymer toll manufacturing unit in Pearland, TX, USA. It allows the production of standard prepolymers as well as the production of specialized products, e.g., by addition of small quantities of additives. During the CPI Polyurethanes Technical Conference 2017 in New Orleans, LA, USA, we had a chance to talk with Steven English, Commercial and Marketing Vice President of Third Coast, about the company’s product portfolio and strategy.

CPI Polyurethanes Technical Conference 2017, New Orleans, LA, USA

The longest-running polyurethanes conference in North America, Polyurethanes Technical Conference presented by the American Chemistry Council (ACC) Center for the Polyurethanes Industry (CPI), this year celebrated its 60th anniversary. To mark this milestone of innovation and progress, more than 1,000 industry experts gathered in New Orleans this year to learn, share ideas and help make the industry even stronger. Over the course of three and a half days, the 2017 Polyurethanes Technical Conference featured 14 technical sessions, 18 posters and 73 table top exhibitors, as well as the Professional Development Program. At this year’s 14 technical sessions, there was something for everyone, with sessions ranging from environmental health and safety, to the latest topics in chemical management, to new applications of polyurethanes technology in the construction industry. The evolving regulatory landscape was also addressed at this year’s conference, with a robust regulatory roundtable discussion and an update from the Environmental Protection Agency (EPA).

Covestro celebrates 80 years of polyurethane

Polyurethanes have changed the world – thanks to them we hace energy-efficient refrigerators, comfortable upholstered furniture, safe car seats, protective coatings and lightweight composites. 80 years ago, Dr. Otto Bayer discovered polyurethane chemistry virtually by accident. His perseverance and creativity launched the sweeping success of one of the world’s most versatile materials.

The European GRP market in 2017 – The trend of steady growth continues

The AVK – Industrievereinigung Verstärkte Kunststoffe has published the 2017 market report for glass fibre reinforced plastics (GRP). In the European countries included in the 2017 study, the GRP market is expected to grow by around 2 % compared to the previous year with production forecast to total 1.118 million t. Growth has thus stabilised in this largest segment of the fibre reinforced plastics and composites industry. Germany remains the European country with the largest GRP production in absolute terms and the strongest growth.

Preview: 29th International Colloquium Plastics Technology – Recruiting – Networking – Innovating: IKV presents its latest research

The Institute of Plastics Processing (IKV) in Industry and the Skilled Crafts at RWTH Aachen University will stage its 29th International Colloquium Plastics Technology in Aachen, Germany on 28 February and 1 March 2018. The institute again expects around 800 experts from the global plastics industry to attend the event, which takes place every two years. In 2016, the delegates came from more than 300 companies and 15 nations. All the papers will be translated simultaneously into English.

Pairing surfactants with non-emissive catalysts for low density open cell spray foam systems

Open-cell low density spray applied foam has proven to be an effective way to seal and insulate with a good balance of economics and performance in residential construction. Traditional emissive catalysts such as BDMAEE have been shown to emit from the spray foam during and after application. It is important to reduce volatile emissions to address concerns for applicator safety and indoor air quality for future building occupants. The best way to reduce such hazards is to remove them from the formulation and to replace them with reactive catalysts that will remain chemically fixed in the foam matrix. However, replacing BDMAEE with a non-emissive catalyst package generates a number of formulation challenges. In addition to system reactivity, there are a number of other factors that will be affected such as cell structure, system stability, and final foam performance. In this paper, we will discuss the importance of surfactant choice when converting to a non-emissive catalyst package.

Open-cell (low density) spray polyurethane foam: Thermal aging study

The ACC-CPI Spray Foam Coalition recently completed a study to evaluate the thermal performance of open-cell spray polyurethane foam (ocSPF) when conditioned up to 180 days (6 months) after spraying. This study, performed on four commercially available ocSPF products, showed thermal performance, measured as thermal resistivity or R-value per inch per ASTM C518, will stabilize within 30 days after spraying. These results suggest that traditional 180 day conditioning used prior to thermal testing may not be needed for ocSPF products.

Characterization of the susceptibility of various types of spray foam insulation to the growth of mold in wall cavities

The use of polyurethane spray foams as the residential insulation product of choice is growing at a rapid pace due to its superior insulating and energy saving properties. The susceptibility of these foams to the growth of mold varies significantly. This variability ranges from one foam, being completely biologically inert to the growth of mold, while another seemingly similar foam being extremely likely to support the growth of mold. One only need review the recent history of the gypsum wall board industry and mold growth in wall cavities to recognize the importance of understanding whether your foams are likely to support mold growth or not. We will discuss reasons for this variability in biological susceptibility between different spray foams in this paper. Methods of determining if a spray foam product will support the growth of mold will be reviewed, as well as the significance and impact of the end-use-environment on mold growth. Simulation of the end-use-environment in the accelerated microbial tests used to determine the susceptibility of a spray foam product will be considered in this paper. We will also review the performance of common antimicrobials designed to control the growth of mold in polyurethane foams as formulation options for spray foams.

Physical foaming of polyurethane with CO2

The Institute of Plastics Processing (IKV) in Industry and the Skilled Crafts at RWTH Aachen University developed within two research projects different concepts for the processing of high proportions of CO2 as a physical blowing agent in polyurethane foams. The approach of the gas counter-pressure technology is currently being extended to include the aspect of a flexible dosing of the blowing agent into the polyol inlet, shortly before the mixing head. Due to the short dwell time of the CO2 in the polyol, previous disadvantages during processing are eliminated. The property profile of flexible foams can be extended so that in foams with a density of 47 kg/m3 the compression hardness could be reduced by approx. 50 % compared to water-blown polyurethane foams to 2.5 kPa.

Industrial hygiene monitoring – Residential attic’s and crawl space insulation upgrade with open cell and closed cell spray polyurethane foam

As part of BASF Corporation's commitment to product stewardship, industrial hygiene air monitoring was conducted during two residential home retrofit spray polyurethane foam (SPF) insulation applications of open and closed cell SPF. Monitoring specifically evaluated whether a confined space atmosphere existed, in residential attic and crawl spaces, during SPF application.
