The most common options for automakers seeking stable and reliable materials for structural components were magnesium, conventional steel or aluminum. The key advantage of the Trinseo’s ABS LGF is that it is a lightweight alternative for semi-structural components, as it enables high stiffness and dimensional stability. The other advantages of the ABS LGF composite are that it offers faster production cycle times, and low VOC and low odor properties.
Trinseo proved the ABS LGF’s performance by using it as an alternative to magnesium in the BMW 3-series’ instrument carrier. By collaborating with Tier One supplier, Dräxlmaier, Trinseo optimized the materials’ warpage, head impact, crash stiffness and the stability of the final component. Norwin van Riel, Trinseo’s Technology leader, said, “With this new ABS LGF alloy product, we have developed a thermoplastic composite that combines high stiffness over a broad temperature range with high dimensional stability, which facilitates lighter weight designs in comparison to aluminum and magnesium. Automotive manufacturers are increasingly looking to reduce vehicle weight without affecting stability. Our new lightweight plastic solution offers an easy processing and lightweight solution.”
