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.

The K 2022 offered an immense range of innovations and application examples for – and with more – sustainable materials. Interestingly hereby was that bio-based versions were extremely popular.

Shoes made from waste gas: genetically modified bacteria produce ethanol from waste gas, which is then used to create plastic, e.g. for the Cloudprime shoes from On.

Is Bio the New Standard?

One of the last major German chemical giants, BASF is fighting back against the weak economy with an extensive efficiency program. Its acquisition of Solvay’s polyamide business has strengthened the engineering thermoplastics value chain. The circular economy is providing most of the new impetus.

PA66 and PBT considerably expand the field of applications for laser sintering by showing better properties than classic PA11 and PA12 materials in most cases.

As a temperature-resistant and flame-retardant material with high mechanical properties, PA66 opens up new application possibilities for laser sintering, such as its use as a sensor holder

From Injection Molding to  Additive Manufacturing

Up to now, the relevant interactions between thermoplastics and metal surfaces at the interface have not been fully investigated. In this article, possible intermolecular interactions between plastics and metal surfaces are described and investigated on injection-moulded composite specimens made of polyamide 6 and polybutylene terephthalate with aluminum as a composite partner. The results of the investigation show that the composite adhesion is mainly based on intermolecular interactions between the composite partners and not on mechanical form-fit. If the polar surface of the aluminum is chemically inactivated without changing its surface topography, then no composite adhesion occurs.

Intermolecular interactions and their influence on the adhesion between plastics and metal surfaces

Optics play an increasingly important role in plastic components. Glossy and even surfaces are decisive for an attractive appearance. With glass fiber-reinforced polyamides (PA), these requirements can usually only be achieved with an additional coating. A PA specially developed for surface design offers an alternative approach.

For visible components, an even, glossy surface is often desired, which is often difficult to achieve with glass fiber-reinforced PA. PA Grivory G7V from EMS now solves this problem

Replacing Metals with PPA Compounds

A rotating mould core can induce shear in the tangential direction during injection, which superimposes the injection-induced shear. In the case of fibre-reinforced thermoplastics, this results in a reorientation of the fibres in tangential direction. This paper shows how a rotating mould core influences the fibre orientation and bursting strength of short-fibre-reinforced polypropylene and polyamide respectively. Furthermore, different wall thicknesses and fibre contents are investigated at varying rotational speeds. Regardless of the used material and the wall thickness, strength increases of more than 75 %are possible at the appropriate speed.

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.

With the change from internal combustion engines to hybrid and electric vehicles, peak operating temperatures have dropped from 135 °C to 110 °C. At the same time, the number of operating hours compared to combustion engines has increased nine-fold. This has an influence on material selection.

Lanxess’ Business Unit to Become Legally Independent

Lanxess will transfer its High Performance Materials unit to an independent legal corporate structure.

The business unit employs around 1900 people at 14 sites worldwide. Sales are in the low single-digit billion euro range.

According to the specialty chemicals company, the High Performance Materials unit (HPM) is one of the leading suppliers of high-performance plastics. The materials are used primarily in the automotive, electrical and electronics industries. Electromobility in particular is a promising field of application for the Lanxess plastics, which are used predominantly for car bodies, battery housings and charging infrastructure.

 “The global market for new forms of mobility is developing very dynamically and is strategically rearranging itself – creating many innovative alliances and partnerships. In order to get the most out of the growth opportunities in this market and to be able to act flexibly, we will create a separate legal structure for the business unit,” said Hubert Fink, member of the Board of Management of Lanxess AG. The company will begin implementation in the first half of 2022.

The portfolio of the HPM business unit includes the engineering plastics polyamide and polybutylene terephthalate, as well as thermoplastic fiber composites. As stated in a press release, the business unit is characterized by the high backward integration of its production processes.
