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 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.

Electromobility and Sustainability Are Driving Growth

Plastic waste in the sea has been shaping the negative image of the industry for several years. Various initiatives and mergers of companies have therefore launched projects to tackle this Ocean-bound Plastics (OBP). Components made of OBP could become a symbol for a sustainable use of plastics.

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.

Enhancing mixed bottle flakes by turning them into extrudable recycled crystalline polyethylene terephthalate (rCPET) was the goal of a joint development project looking to close the gap in the PET recycling system. By successfully producing a sheet made from recycled material suitable for high-quality applications such as thermoformed food trays, Gneuss, Sukano and Illig have demonstrated that this approach is indeed possible.

The injection molding system supplier Husky is launching its HyPET HPP5e. This is a refinement of the proven HPP platform, which, as a fully integrated system for the manufacture of PET preforms, is intended to obtain greater energy savings, system reliability, preform quality and user friendliness than its predecessor.

The HyPET HPP5e is claimed to achieve up to 7 % energy saving compared to the predecessor model

The concept of bioplastics as sustainable and environmentally friendly materials has become increasingly interesting in both academia and industry. Consequently, many researchers have made great effort in developing bioplastic materials. As new challenging materials, there is still a lack of in-depth understanding of the process−structure−property relationships, especially in multi-phase component nanocomposites.

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.

Extending the Limits of PVC

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.

Polyplastics introduces new Duranex 201EB PBT resin for millimeter wave radar for automotive applications.

The Polyplastics Group presents a new electrically conductive grade of polybutylene terephthalate (PBT) for millimeter wave radar applications for the automotive industry.

Duranex PBT 201EB provides the benefit of electromagnetic wave shielding as an added effect of electrical conductivity. As a result, the material contributes to reduced assembly work and cuts cost, as stated in a press release. 

In today’s advanced driver assistance systems, millimeter wave radar is a type of sensor that measures the distance, speed, and angle of objects such as approaching cars by sending and receiving radio waves (electromagnetic waves) in millimeter wave bands. The market for millimeter wave radar is rapidly expanding due to increased use for periphery monitoring of vehicles, including on the rear side, thanks to its ability to accurately recognize distances and other parameters in inclement weather and at night. 

Polyplastics has worked to produce materials for millimeter wave radar applications through varied approaches. The use of electrically conductive grades like Duranex PBT 201EB in radio wave absorbing materials can contribute to reduced processing costs for customers and enables greater design freedom.

Previously, electromagnetic wave absorbing materials have been partially incorporated on the back side of radomes that transmit electromagnetic waves. Incorporating electromagnetic wave absorbing materials has the effect of reducing millimeter wave reflection noise and inhibiting the occurrence of detection errors (increasing accuracy of detection). However, a process to attach conventional rubber electromagnetic wave absorbers to the back of radomes has been problematic. According to the company, Duranex PBT 201EB has the same PBT resin base composition as radomes, and it also bonds extremely well due to its double-shot molding capability.

The new Duranex 201EB PBT resin is suitable for millimeter wave radar for automotive applications.
