ExxonMobil Chemical endorses the principles of sustainable development, including the need to balance economic growth, social development and environmental considerations. BASF Ludwigshafen, Germany will feature a number of material and manufacturing solutions for applications in the automotive, wind and marine markets.The first part featured is the BMW i3 seat pan, manufactured from carbon fibers and a polyurethane matrix. The self-supporting rear seat pan for the BMW i3 was produced using the Elastolit PU system from BASF by the automotive supplier F.S. Fehrer Automotive. Here, carbon fiber materials were used in”bination with a PU matrix for the first time in a production vehicle.
The”ponent integrates a variety of functions such as a cupholder mount and storage shelf, eliminating assembly operations and saving weight. Elastolit from BASF is characterized by its wide process window as well as high fatigue strength and damage tolerance. Thanks to the special properties of the material, the crash-relevant part fulfills the strict safety requirements of BMW despite its wall thickness of 1.4 mm/0.05 inch.Machinery manufacturer Mahr Metering Systems and BASF have been jointly developing material and system solutions for the T-RTM process thermoplastic resin transfer molding. At JEC, Mahr will exhibit an initial prototype of a self-cleaning mixing head that is part of a machine concept for processing reactive polyamide by means of inexpensive low-pressure RTM technology.
At the same time, BASF has been optimizing its first reactive polyamide systems for these economically relevant, fast production cycles. These are two”ponent systems based on caprolactam, an appropriate additive system and fibers with”patible sizings. These systems feature low viscosity and long flow paths”pared to other reactive resins, making them especially suitable for low-pressure RTM technology. Through this joint effort, the two”panies hope to facilitate the introduction of anionic polymerizing polyamide 6 to the market – for volume production of structural thermoplastic”posite”ponents.
