Innovative high-performance polyamides for E-mobility

EMS-GRIVORY, the leading company and pioneer in the development of polyamides, is presenting a wide range of varied high-performance polymers, especially developed to meet the requirements of electromobility, at the Fakuma in Friedrichshafen (Stand B2-2113) from October 17 – 21, 2023.

Focus on flame protection

EMS-GRIVORY offers a wide range of flame-retardant polyamides with no halogen or red phosphorus content, which are ideal for the development and manufacture of components in the high-voltage range of electric drive systems. Our product assortment includes both reinforced and unreinforced PA6, PA66 and PA66+6 products, as well as lead-free solderable polyphtalamides (PPA). One example from our portfolio is Grilon XE 16079, a polyamide with a glass fibre content of 30 percent, which was specially developed for components with long flow paths such as battery carriers. EMS also offers flame-retardant and long-fibre-reinforced products (LFT) for the production of safe and durable charging connectors (Fig. 1).

Key function hydrolysis stability

EMS-GRIVORY offers Grivory HT1VA grades, specifically developed for use in the cooling systems of electric vehicles. These products are characterised by their excellent resistance to hydrolysis and heat. In direct comparison to conventional PA 66 materials, Grivory HT1VA shows more than three times higher breaking stress after storage for around 8,000 hours in a 1:1 water-glycol mixture at 110°C (Fig. 2). In addition, electro-compatible stabilisation makes seamless integration of electrical components possible.

Core component electrical insulation

With reliable dielectric strength at high temperatures and in humid environments as well as an impressive tracking resistance of 825V, Grilamid TR XE 10991 opens up new perspectives for the insulation of electrical conduits. In contrast to PA 12, the dielectric strength of Grilamid TR XE 10991 remains constant even at elevated temperatures, which further increases its application versatility (Fig. 4).
