My Annual Review 2021 and Outlook for 2022

 

Hello and welcome to my end-of-the-year review 2021 and outlook for 2022.

“Expect the unexpected”

2021 was another year under the umbrella of “expect the unexpected”, not only for the plastics industry, but also for the world economy and societies.

We have seen major supply chain disruptions due to Covid-crisis, the North American winter storm (“Uri”) which also led to force majeure at chemical companies in the Texas region, combined with the Suez Canal blockage after the grounding of Ever Given.

Apart from price increase roller coasters and force majeure, big chemical companies start to streamline their portfolios and start divesting. DSM, DuPont, and Lanxess already announce their divestment of their plastics divisions. More are likely to come and at the end of this decade we see a new chemical company landscape.

Top 5 most popular blog posts published this year

On the blog, the journey continued with several posts per month on different polymer engineering and plastics topics to help show that plastics contribute to solving major problems and not cause them.

Below an overview of the top 5 posts of this year

1. Eco-profiles of Polymer Resins – Global Warming Potential

2. Bio-Based Polyamides – Part 1: PA 5.6 and 5T(Chemical Structure, Production, Properties, Applications, Value Proposition)

3. Guest Interview: Doug EOM – POKETONETechnical Support Engineer from Hyosung Chemical – “Polyketone can becharacterized as strong, tough, and ductile.”

4. Joining Techniques - Laser Welding of Plastics

5. HDPE Plastic Bag Degradation - The Experiment

Outlook on 2022

In 2022, I will continue to present posts which evolve around 4 main categories:

- Sustainability in plastics (Circular Economy, sustainable design, renewable plastics, recycling of plastics, ocean water plastics, eco-profiles)

- Polymer material selection

- Design properties for engineers (incl. eco-design for sustainability in plastics) and Rules of Thumbs in polymer engineering

- Leadership and strategy in plastics industry

Furthermore, I invite you all to leave topics you would like to read about in 2022 in the comment box below or leave me a short message here.

Last but not least, I would like to thank all readers of my posts!!!

I hope to welcome you again next year.

Polymer Material Selection Support for E-Mobility [Infographic]

 Hello and welcome to a new infographic on the polymer material selection for electromobility. 

In general, electric cars require new components such as power electronics (inverters, converters), traction motors, high-voltage charges and lithium-ion batteries. This in turn changes the requirement profile of plastics. I discussed the requieremnt changes in this three part series as well as in my EMI shielding posts. In my five part video series I discuss the electrical design properties in detail. 

Below I summarized the material requirements vs. polymeric materials and materials for different operating temperatures for high voltage components.

Eco-profiles of Polymer Resins – Global Warming Potential

 Hello and welcome to a new post. Today we discuss the topic of global warming potential of polymer resins as part of eco-profiles.

Life cycle analysis (LCA) and eco-profiles

In general, eco-profiles are used to determine the environmental impacts of plastics. They are made out of different data sources. For instance, PlasticsEurope.org uses Life Cycle Inventory datasets (LCI) and Environmental Product Declarations (EPD) to calculate the eco-profiles for plastics.

For having a 360° view on the environmental impact, several values are estimated:

• Global Warming Potential (GWP)
• Ozone Depletion Potential (ODP)
• Acidification Potential (AP)
• Photochemical Ozone Creation Potential (POCP)
• Eutrophication Potential (EP)
• Dust/particulate matter
• Total particulate matter (Non-hazardous / hazardous)

In this post we focus on the Global Warming Potential (GWP) value only. The estimation is based upon life cycle inventory (LCI) data from PlasticsEurope's member companies. It has been prepared according to the rules of PlasticsEurope’s Eco-profiles and Environmental Declarations – LCI Methodology and considers from cradle to gate (i.e. from raw material extraction to polymer resin at plant).

Environmental Performance

The figure below shows the Global Warming Potential (GWP) associated with the production of 1 kg of polymer resin.

Eco-profiles: Global Warming Potential (GWP) associated with the production of 1 kg of polymer resin

Updated with bio-based long chain Polyamides, High Performance Polymers and Polyesters. 

Eco-profiles: Global Warming Potential (GWP) - raw data (updated with Bio-based polymers and PVOH)

Conclusions

Eco-profiles are a vital part for businesses to select their materials in the context of a circular economy and low environmental impact. Results such as the Global Warming Potential may even enter the technical data sheets of material manufacturers which allows purchasers and engineers to pre-select the polymer resins.

Furthermore, the data of plastics indicates a lower GWP level compared to competing metals such as Magnesium (25.8 kg CO2 eq/kg Mg) and Aluminum (9.7 kg CO2 eq/kg Al).

Also, I have written about bio-based polymers and circular economy here and here.

Overcoming Automotive Challenges in 2021: Replacing Magnesium Die Casting with Engineering and High Performance Plastics

Hello and welcome to a new blog post based on the recent events of Magnesium shortage in the automotive industry.

The automotive sector already has it’s fair share of challenges in 2021. Chip, plastics, and container shortage were meeting a high demand triggered by pent-up consumption due to the Covid-19 crisis in 2020.

Now another challenge came up: export of Magnesium from Asia. Energy crisis in China caused a lowering of energy intensive Magnesium production. Many Tier-1 suppliers in Europe which use Magnesium die casting to make gear boxes and steering applications suffer under this low export rate (China provides more than 50% of the global Magnesium production).

This offers engineering and high performance polymers to jump in and replace the one or the other applications such as housings and bezels.

Figure 1 compares different polymers (mainly with Carbon fiber loading) to Magnesium AZ91D, a commonly used automotive alloy. It can be shown that engineering polymers such as PA 6 and 6.6 with carbon fiber loading as well as high performance polymers such as PPS, PARA, and PPA (with CF loading) can replace Magnesium. PPS and PPA offer the advantage of high temperature durability and low water uptake.

Figure 1: Specific tensile strength vs. specific tensile modulus overview for replacing Magnesium with engineering and high performance polymers

Apart from cost and weight saving - what are some more advantages of replacing metals with plastics?

There is the possibility of consolidating several metal parts into one plastic part and having a better resistance to corrosion or chemical attacks. Also acoustics (particularly relevant in electric vehicles) can be improved, together with an improved friction and wear of parts.

How to do a metal replacement?

This I discussed in the following blog post here and additionally made a training video on YouTube of it:
