Because of its good temperature resistance, impact resistance and aesthetics appearance, acrylonitrile-butadiene-styrene is often used in household goods and in the automotive industry. The development of a circular economy also shows successes.

More than half of the world’s ABS consumption is accounted for by household and E&E equipment

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.

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

Profiles made of rigid PVC have many advantages: they are easily extrudable, inexpensive, and with suitable additives, they exhibit good UV resistance. However, regarding its mechanical and thermal properties, PVC occasionally reaches its limits. This shortcoming can be evaded by co-extrusion with a PBT blend.

If the properties of pure PVC profiles are inadequate, PBT co-extruded versions are an option. For example, their thermal expansion and post-shrinkage when heated are lower.

DSM sells its Engineering Polymers business to Lanxess and the financial investor Advent. In return, the two companies are setting up a joint venture to which Lanxess is also contributing its PA and PBT business.

Lanxess is outsourcing its engineering plastics business to the joint venture.

The global market for PBT has recovered well from the aftermath of the corona pandemic. However, there is a lot going on among manufacturers at the moment.

PBT compounds are very much in demand for electromobility, including for parts of the battery, electric transmission and the charging infrastructure.

Polybutylene Terephthalate (PBT): Demand for Products with Added Benefits

Electromobility and Sustainability Are Driving Growth

Styrenics can be polymerized using different technologies and it can be modified with a range of copolymers. The resulting plastics offer a wide range of properties allowing to customize them for different applications. Because of this range of properties they are suitable for many industries. Strong demand is for example driven by the automotive industry, healthcare and the packaging industry.

Styrene copolymers are frequently used in the exterior of vehicles. The Chinese manufacturer Lixiang, for example, uses an ASA for the radiator grill of its electric vehicles

Diverse Shapes and Applications

Lightweight construction, functionality and design are characteristic of material development in all areas of application for PC compounds, composites and films. The range of materials has enormous opportunities when it comes to the mobility of the future, lightweight structural construction with continuous fiber-reinforced composites, 5G technology and medical technology.

In electric vehicles, the original function of the radiator grille, namely to supply air to the engine, is no longer needed. It can therefore be used entirely as a design element, for example by integrating luminous logos and fade-out effects

The transformation from the combustion to the electric engine entails several imponderabilities for the plastics industry. In part, electric drives have completely different material requirements which are becoming specifically evident with the increasing use of appropriate vehicles.

In electric vehicles, the change in engine technology also entails new requirements for the plastic materials used

Harmoniously integrating displays into the lines of a vehicle cockpit has always been a real challenge. Continental now uses a combination of film insert molding, in-mold decoration and injection-compression molding to produce large, three-dimensionally formed plastic panels.

Replacing metal with polyamides (PA) in components can not only reduce weight and costs, but also offers developers greater design freedom. However, this requires materials with improved mechanical properties.

There is still a need to catch up in terms of ion leaching and hydrolysis resistance of the materials used to date for fuel cells. Specially developed PPS represent one possibility for this.

Getting Fuel Cell Vehicles Fit for Use

Alternative powertrains, autonomous driving and the urge for more sustainability impact the vehicle design and driving experience.

Particularly, the car interior is experiencing a unique transformation. It is changing into a mobile office and living room. Applications such as the instrument panel are transformed into entertainment units with screens for video conferencing. Electronic devices with additional functions require ever higher data rates. This represents immense requirements for the high-performance equipment and, thus, for the electronic components and materials used. In addition, it is necessary to reduce weight and to use smaller components due to less space.

MD Elektronik has taken on these challenges and presented the new connector system C-Klic based on USB Type-C standard. It is suitable for use in vehicles and enables space saving of up to 60 % compared to standard USB ports. Moreover, the device shows a data transfer rate of >10 GB/s. For the system, the electronics manufacturer uses BASF’s glass fiber-reinforced polybutylene terephthalate (PBT) Ultradur B 4300 G4.

“Our goal was to produce as many individual parts of the connector system as possible with one identical material. This simplifies processing, is much more efficient and contributes to sustainability by reducing material changes on the production machines“, said Johannes Trä, Director Development at MD Elektronik.

The PBT is used in the Connector Position Assurance (CPA) element, coding housing and internal overmolding. Especially in the internal component the PBT displays its full strength, according to BASF. Thanks to excellent electrical properties and superb dimensional stability, the engineering plastic protects the sensitive electronics from external influences like humidity and dirt.

Moreover, the PBT fulfills another important aspect. “Due to the very good dimensional stability and low humidity absorption, the tight tolerances can be maintained regardless of the ambient conditions in the vehicle”, explains Volker Zeiher, Senior Specialist Technical Development at BASF. Compared to a standard USB charging module with integrated electronics, the new connector system can be produced in much smaller dimensions which saves installation space and weight.
