EMS-GRIVORY The leading manufacturer of high-performance polyamides

Cutting-edge metal replacement

Through focussed improvement and further development of EMS polyamide specialities, replacement of metal is possible in increasingly demanding applications. The properties of partially aromatic polyamides in particular, such as polyphthalamides, have been significantly enhanced. This is illustrated by one of our latest products: Grivory G5V, which shows a significantly improved performance at higher temperatures.

The latest products to have been developed by EMS for metal replacement applications, are Grivory G5V and Grivory HT6. Both products expand the application opportunities for polyamides into higher temperature ranges and enable the cost-efficient production of lightweight components, which until recently could only be achieved with metallic materials. The improved creep resistance of both products allows lower wall thicknesses to be used, allowing cost and weight savings to be achieved - even compared to other metal replacement solutions.

Grivory G5V: The polyamide for metal replacement up to 100 °C

Grivory G5V has been developed for applications at temperatures of up to 100 °C. The stiffness of the material (measured as modulus of elasticity) in a conditioned state at 80 °C is 45 % higher than that of the tried-and-tested classic, Grivory GV. This is due, among other things, to reduced moisture absorption, which also ensures improved dimensional stability. The improved stiffness at higher temperatures makes component designs with lower wall strengths possible, which is further facilitated by a 35 % improvement in creep resistance compared to Grivory GV. This allows cost and weight savings to be achieved. As is usual for Grivory GV components, the mechanical properties of the product remain practically unchanged, even after conditioning (moisture absorption) and Grivory G5V is also easy to process using injection moulding methods. Grivory G5V has been designed for use in structural components in automobile interiors, such as instrument panel supports, air vents and seat shells, as well as functional components in mechanical engineering, furniture fittings and fastening elements, where the material’s stiffness at temperatures of up to 100°C and low tracking index are important.
