RE3 – What’s that?

I admit that in retrospect, 2019 will certainly not be one of my favorite years in many respects, but uncertain and challenging times always bring something good with them, if you continue to move forward with confidence and courage, act counter-cyclically!

And so, in a time of economic uncertainty and the associated cutbacks in advertising budgets, trade conflicts, “plastic bashing”, and the demise of publishing houses, we have dared to launch a new magazine at K 2019:

The focus of RE3 is on Circular Economy. The three keywords “REduce”, “REuse”, “REcycle” appear again and again. In RE3 you can read what they stand for, and which interesting approaches and solutions are available. The magazine is published four times a year in German and English in PRINT and online. Visit www.re3.today and follow us also on Twitter and LinkedIn. Issue 01 will be published at the end of March.

The content of the magazine’s coverage focuses on solutions the industry is developing – new products, technical developments and information about companies that provide systemic solutions. In addition, it includes definitions of terms, scientific research results, pro-con comparisons, business news and articles about people in the industry and associations.

A critical view of the ongoing discussion is also necessary within the industry. Our focus is on a future-oriented and responsible handling of the valuable material plastics. “Green Washing” is out of place in RE3.

Although RE3 is not a technical magazine, it is managed in terms of content and sales by the expert staff of Dr. Gupta Verlags GmbH, who are also your contacts for all questions. RE3 is published by INDIGU Publishing.

With a new publisher, we have the opportunity to contribute with expertise and knowledge to the social discussion about the pros and cons of the various plastics in our everyday lives – extending the scope beyond the plastics industry.

Confident that our courage has paid off, and hopefully with your support, we look forward to communicating the know-how of the industry and the future possibilities and solutions to an ever broader audience.

Warmest regards
Indira Gupta

Global automotive markets 2020 – Industry under economic and transformation pressure

The automotive industry is under economic and transformation pressure worldwide. On the one hand, the transition to electric mobility must be shouldered. On the other hand, the poor state of the industry as a result of the US customs wars under President Donald Trump is causing concern. Switching to electro mobility will result in the loss of jobs in the industry, which cannot be compensated for by the growth processes in the coming years. Important value creation in the internal combustion engine sector will be lost bit by bit and replaced by highly automated battery and electric motor production.

Isocyanate-free polyhydroxy urethanes for water-borne coating applications

Polyhydroxy urethanes possess the potential to complement the portfolio of PU coatings and related applications. We describe a promising procedure to obtain waterborne isocyanate-free urethane comprising polymers and their use for coating applications. The synthesis of the polyhydroxy urethanes in solvents bases on a charge stabilization procedure leading to stable water based polyhydroxy urethane dispersions with up to around 40 wt% solid content. Raw material properties, film formation, and coating properties of around 0.1 mm thickness were also explored. First results focus on coatings for wood applications. Interestingly, the hydroxyl offers several possibilities to modify this raw material expanding the availability of this interesting material in coating sciences.

Thermal, mechanical and adhesion properties of polyurethane reactive hot melt adhesives prepared using bio-based 1,3-propanediol and 100 % renewably-sourced poly(trimethylene ether) glycol

A series of polyurethane (PU) reactive hot melt adhesives (RHMAs) were prepared from 4,4’-diphenylmethane diisocyanate (4,4’-MDI) reacted with poly(1,3-propylene alkanedicarboxylate) diols of different chain lengths, and combined with 100 % renewably-sourced polytrimethylene ether glycol (PO3G) or poly(oxypropylene) glycol (PPG). The morphology and adhesion properties of these PURHMAs were investigated using differential scanning calorimetry (DSC), dynamic mechanical thermal analyzer (DMA) and tensile testing. PURHMAs prepared with the two different polyether diols, PO3G and PPG, generate significantly different values for glass transition temperature, crystallinity properties, open time, and bulk tensile strength. The resultant PURHMAs prepared from poly(1,3-propylene alkanedicarboxylate) and sustainably-derived PO3G exhibit excellent adhesion properties to multiple substrates including plastics (PC, ABS) and metals (aluminum, steel), which is comparable to or better than those prepared from poly(1,6-hexamethylene adipate) diol (PHA) or PPG.

Flame retardancy of polyurethanes

Polyurethanes (PU) represent one of the most versatile classes of plastics. They are processed and used as thermoplastic, elastomer, and thermoset. The requirements regarding flammability are correspondingly versatile. Depending on the material and the field of application, specific fire tests have to be fulfilled. This paper describes the different concepts used to fulfil these requirements by choosing the right raw materials and flame retardants.

Effective additives for improving abrasion resistance in polyurethane elastomers

Polyurethanes have been long known for excellent abrasion resistance, especially when compared with other materials such as rubber, plastic, and metal. However, the abrasion resistance can be further improved by the addition of additives. In this paper, the effect of various additives on the abrasion resistance (ASTM D5963-Rotary Drum Abrasion) of various polyurethane systems will be presented. Multiple isocyanates, polyol backbones, curatives, stoichiometric ratios, and multiple additives will be evaluated in an effort to identify the most effective routes to improving abrasion resistance without compromising the physical/mechanical properties. The methods of incorporating various additives will be discussed as well.
