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.

Fig. 1. Crosslinked engineering plastics can be used for many different applications in electric vehicles.

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

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.

For many components, the use of metal-replacing plastics is an attractive possibility e. g. to save weight and benefit from enhanced design freedom. In various applications, however, the thermal conductivity of the polymers is of equal importance. There are different additives that can be used to enhance this property. In the development of two polyamide families, Domo Engineered Materials investigated which of those additives are especially useful to this end, and applied Light Flash Analysis to examine the materials.

Heat Transfer with Plastics versus Metals

Electrical architecture in an E-car is significantly more challenging than for conventionally powered vehicles. Particularly for insulation of high-voltage (HV) components, the demands on the materials used are increasing. With specially-tailored materials for electric vehicles, challenges in automotive high-voltage technology can be overcome.

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.

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.
