For a specially good combination of toughness and stiffness, even in high-temperature applications, the TER Plastics Polymer Group, Herten, Germany, is exhibiting its Terez LFT range of grades with good fiber adhesion at the Fakuma trade show. A new product in the range, which usefully complements existing long fiber compounds, is Terez GT3 HLG40 with reduced water absorption. Tribological requirements, even at high temperatures, can be fulfilled with the newly developed grade Terez HT 100 H G30 TF15. According to the manufacturer, special chemical coupling of the lubricating component allows maintenance-free use over long periods. With standard polyamides, glass fiber contents of up to 65 % are now available, which enable high stiffness and strength as well as good surface quality to be achieved.

Whether it was the motto presented by the trade fair’s committee or threatened prohibition proceedings: material producers are getting more involved with sustainability. While some are participating in campaigns and initiatives, others are investigating more closely the basis of their raw materials and their products. In view of the challenge to create a circular economy for plastics, all other topics take second place this year.

How to Make Plastic Compounds out of Packaging Waste

With a glass fiber-filled PA6, Lanxess has presented the first product in a product family specially manufactured from sustainable raw materials. The materials for this come e.g. from the energy group bp.

Lanxess’ Business Unit to Become Legally Independent

Until now, polyamide 66 was the main material used for coolant applications in automobiles. Due to increasing requirements, however, alternative materials such as PPS and PPA are becoming increasingly interesting for components. This is illustrated by the example of a coolant distribution pipe for Audi and VW vehicles.

Fig. 1. Since the two-piece coolant distribution pipe was to be joined by rotation welding, PPS was out of the question as a material.

Alternatives to PA66

The Chinese automotive manufacturer Geely will in the future use a polyamide 6 (PA6) from Lanxess for front-end (FE) carriers in its vehicles.

 PA for a Front-End Carrier

Vehicle weight reduction requirements today pose great challenges not only to automotive manufacturers and suppliers but also to material producers. The materials used must cut weight while at the same time withstanding the mechanical and chemical stresses encountered in service. This can be achieved, for example, with blends of polyamide and polypropylene. These blends also offer other useful advantages.

Most of the energy in a crash is absorbed by metal parts. A new additional polyamide (PA) crash absorber has for the first time been integrated into the front end of the Mercedes-Benz S-Class. The advantage is that an additional loadpath could be added without significantly increasing the mass of the car.  Close cooperation between the project partners and the use of suitable simulation tools were key to successful realization of this project.

As part of the safety concept in the front end of the latest S-Class, Mercedes-Benz uses a crash absorber made from polyamide.

Accident Protection with Plastics

Electric-vehicle makers looking for fresh impetus are turning to thermoplastics, as these can be used to  improve the safety, performance and sustainability of the vehicles. Initial application areas for manufacturers can be found in a multitude of components ranging from battery cases to busbars, cooling lines and seals. Things become very interesting when material suppliers offer support in the form of CAE and injection molding analyses.

Thermoplastics play an important role in the batteries of electric vehicles. They help to keep battery temperatures in the optimal range for a long service life and high performance. 

Improving the Performance of Electric Vehicles with the Right Materials

The conditions in electric vehicles place high demands on the materials used. Therefore, automakers and suppliers must resort to expensive, high-performance plastics. For many applications, cost-effective alternatives are plastics whose properties have been greatly improved by means of treatment with high-energy electron beams.

Domo Chemicals invests to expand production capacity of Technyl polyamide in China to meet growing market demand.

Domo Chemicals will expand the capacity of its production site in Jiaxing, Zhejiang Province in three stages.

 Capacity Expansion in China

Electromobility in particular, but also many other electrical applications, are asking for ever higher demands regarding the electrical properties of thermoplastics. This raises the question of whether the polymers commonly used in this area can still meet these demands. The plastics manufacturer, Lanxess, has now investigated how suitable, for example, polyamide and polybutylene terephthalate are for use at higher voltages and temperatures.

How Suitable Are PA and PBT for High-Voltage Applications?

BASF is expanding its portfolio of flame-retardant engineering plastics for electric vehicles. The new PA66 type Ultramid A3U44G6 DC OR is reinforced with 30 % glass fibers.

The new PA66 type is flame-retardant and meets all the criteria of color stability and heat aging resistance. This enables long-lasting color coding, which is safety-relevant in the sensitive area of high voltages in electric cars.

Lanxess and Advent to Buy DSM‘s Engineering Plastics Business

DSM Engineering Materials increases its high-performance materials production capacity at its Jiangyin plant in Jiangsu Province, China. Work on an additional compounding line began in February 2022, with completion expected in 2023.

The new line will help DSM to meet growing demand for high-performance polymers used in a wide range of end-applications – particularly for electric vehicles and in electrics, and electronics – and will help drive the shift to a low-carbon, circular economy.

In recent years, rising living standards and increasingly ambitious environmental policies have driven demand for sustainable high-performance materials in China. Supplying the automotive, electrics, and electronics markets, China’s specialty engineering materials industry continues to show a healthy growth rate. The new state-of-the-art compounding line will help meet this demand for high-performance specialty materials such as PA6/PA66 (Akulon), PET/PBT (Arnite), TPC (Arnitel), PA410 (EcoPaXX), PA4T/PPA (ForTii) and PA46 (Stanyl).

In addition to increasing production capacity for materials enabling sustainable solutions, the expansion project will deliver no increase in greenhouse gas (GHG) emissions upon start-up and will be powered by 100% renewable electricity. This aligns with the sustainability commitments of DSM Engineering Materials, which include halving its global GHG emissions and launching bio- and/or recycled-based alternatives for its whole portfolio by 2030. As stated in a press release, the Jiangyin site is already a frontrunner in sustainable manufacturing, using self-generated solar power and sourced renewable electricity to produce high-performance materials.

Caroline Mitterlehner, Vice President Specialties DSM Engineering Materials, commented: “China is an important and fast-growing country for DSM Engineering Materials. As such, we aim to strengthen our business partnerships by continuing to invest in key areas of sustainable growth. The Jiangyin site’s new compounding line enables us to further expand our specialty materials offering for customers in China, supporting their growing demand for sustainable electrics, electronics, and automotive products.”

Jason Zhang, Vice President Performance Polymers and General Manager China for DSM Engineering Materials, commented: “Our new production line in Jiangyin is a key milestone for DSM, underlining our commitment to supporting our customers, enabling sustainable living, and seizing growth opportunities in China. Together with our customers, we are ready to take the next important steps in our sustainability journey, drive the shift to a low-carbon, circular economy, and create brighter lives for all!”
