Odours from virgin and recycled polyolefins
Braskem
​Angélique Blondy, Sampat Singh Bhati
​
Polyolefins are most common polymers used worldwide, especially in the food packaging and automotive sectors. Strict regulations and better consumer perception are the key drivers for low VOC and low odour products in these segments. Additionally there is an increased demand for a higher quality of recycled materials with low odour profile. We would like to present the importance of understanding the odour profile in virgin and recycled polyolefins, using state of the art analytical tools and show how these tools can support us to select options to improve the odor profile of plastics.

Leather Smell Impact on Chinese Automotive Market
TFL Ledertechnik Ag
​
For most western countries, that rich, sweet, musky smell of new-car leather is a big part of its appeal. Not so for the Chinese. They can’t stand it. For these reason auto interior odours and volatile organic compounds emissions are coming under more scrutiny in China. Odour testing is a super subjective test, because is done by the human nose. What is pleasant for me is different for others and this is more accentuated across regions globally. Getting rid of an odour can be difficult but understanding the chemistries of these volatile compounds is possible to minimise the risk of unpleasant smells in car interiors. Over this presentation we will discuss the root cause, on the what and why smell in China is a problem not solved yet. To answer these questions, we need to understand what our sense of smell means, how leather smell is tested, and which volatiles compounds comes from leather.

Emissions and odours from pilot scale recycled methyl methacrylate and derived polymers
Certech
​
An innovative approach for recycling end-of life poly(methyl methacrylate) (PMMA) by thermal depolymerization is being upscaled using an extrusion-based process. Characterisation of the volatile organic compounds (VOCs) and odors of the regenerated methyl methacrylate monomer (rMMA) and the rPMMA produced therefrom are critical in order to validate these products compared to their virgin counterparts. The presentation will focus on the methodologies used and the identification of the molecules of interest, especially those recombination products originating from the depolymerization mechanism as well as residual comonomers from mixed streams.

Development of an efficient procedure for the analysis of the emissions of very volatile organic compounds (VVOCs) in emission measurements from construction products and in the indoor air
Bundesanstalt für Materialforschung und -prüfung (BAM)
​
The ISO 16000-6 standard describes a method for the determination of volatile organic compounds (VOCs) in indoor and test chamber air by sorbent-based active sampling, thermal desorption and gas chromatography coupled with mass spectrometry (GC/MS). It also gives directions to adapt this methodology to very volatile organic compounds (VVOCs). Indeed, toxicologically based guideline values are being implemented for these compounds and it becomes necessary to measure them. But a comprehensive and robust measurement method is lacking. Investigations on the use of gaseous standards, the suitability of chromatography columns, the suitable sorbent combinations and the water removal are required. The talk will highlight the points that need to be explored towards the standardisation of a suitable procedure and provide appropriate preliminary results.
High Resolution Mass Calibrated HPLC Analysis of 2-Ethylacrolein on TiO2 Pigments
Kronos
With this contribution we present a simple procedure for a sensitive mass calibrated determination of volatile organic compounds (VOC’s) using the example of 2-Ethylacrolein (AEA). Worldwide currently about 7.000.000 t of TiO2 are traded every year. Among the wide variety of applications, there are some that currently carry molecules which are able to produce AEA by accidental application of temperature. KRONOS as TiO2-pigment producer started development of a ppm calibrated method for detection of volatile organics. This high performance liquid chromatography (HPLC) method was designed on the base of derivatization with 2,4-dinitrophenylhydrazine (DNPH). On the one hand this HPLC method could be used to detect the outgassing of molecules (here AEA) from pigments at elevated temperatures and on the other hand it could also be used to prove the existence of molecules (here AEA) on the surface of particulate products as well. Both procedures will be reported.

Emissive properties from 3DP filaments and printed objects from post-industrial and post-consumer recyclates
Certech
​
High added value applications like 3DP filaments are an attractive outlet to upcycle polymer recyclates. The presentation will show how different post-industrial as well as post-consumer recyclates can be processed into calibrated 3DP filaments compliant with the printing process and delivering printed parts with satisfactory aspect, mechanical and emissive properties.

Black masterbatches for VOC reduction in automotive interiors
Cabot Corporation
Cabot specialty compounds business has recently introduced its low odor product line of black masterbatches. These black masterbatches were introduced specifically with the objective of developing a technology and new solutions that enable customers to reduce the voc in automotive interiors. Our new black masterbatches incorporate a proprietary formulation technology to enable the delivery of this performance.
