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.

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.

 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.

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.

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.

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.

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

Domo Chemicals, a global leader in engineered materials, plans a long-term investment in China to continue expanding its production capacity of Technyl high-performance polyamides.

This plan aims to meet growing demand in the automotive, electrical & electronics, and industrial consumer goods industries, and help build a sustainable future.

Domo Chemicals acquired Solvay’s Performance Polyamides business in 2020 and has sold the Technyl products globally since February 1, 2022, including in China, one of the company’s key strategic markets.

Investing More in Expanding Production Capacity in China

According to the company, Asia is the fastest growing market for polyamides in the world, with the majority of that growth concentrated in China. As an integrated producer of PA 6/66, Domo Chemicals is committed to improving and expanding its production facilities in China in order to increase capacity and establish a strong presence.

To this end, Domo Chemicals will continue to expand the capacity of its production site in Jiaxing, Zhejiang Province, which has been planned to be gradually introduced in three stages:

<ul><li>Since March 2022, an additional 6000 t of capacity has been made available, with the plant achieving the total capacity of 14,000 t of PA6 from April onwards.</li><li>A 35,000-t new plant in Haiyan is planned to be completed in the third quarter of 2023, in which the company has invested more than EUR 14 million (97 million yuan).</li><li>Going forward, the company will further expand the plant, gradually increasing its capacity to 50,000 t.</li></ul>

In addition to the expansion, the plant will also use renewable energy wherever possible, adopt advanced water and air treatment technologies to reduce water consumption and CO2 emissions, and fully comply with Health, Safety and Environmental Management System (HSE) regulations. Domo Chemicals will improve HSE compliance continuously and work closely with the local government, while partnering with key local and global customers to accelerate innovation and development across a wide range of industries.

The Domamid, Econamid and Thermec engineered material solution brands are gradually being combined under the Technyl high-performance polyamide family. Technyl 4 Earth is an environmentally friendly product based on recyclable materials and certified for CO2 reduction. The new plant will be equipped with the capability of offering Technyl 4 Earth.

Fabrizio Cochi, Vice President Asian Operations: “Achieving the global rollout of Technyl is a key milestone in Domo Chemicals’ sustainability strategy to help our local customers in China to achieve their low carbon goals and increase their competitive advantage in the face of accelerating sustainability trends.”

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