...natively, airbags can be installed above and below the bumper. Engineering thermoplastics, such as the PC+ABS blend (grade: Bayblend) or the polyester Pocan for the trim, and polyurethanes — in the form of Bayflex for the trim and Bayfill for the absorber foam — are ideal construction materials for such passive bumper systems. The trims — both thermoplastic and PU-RIM — can be produced with optimised weight and in short cycle times by thin-wall technology. Advantages of the PU absorber include i...

...nted for the thermal insulation of pipes and other hollow articles in which the mixing head is pulled through a cavity (Fig.1). The foamed polyurethane then fills out this cavity without any seams. The systems presented by Bayer MaterialScience – Bayfill NV (NV stands for "Noise and Vibration") and Bayfill ST (ST stands for "Structural") – are used to avoid noise and suppress vibration and also to increase the structural stability of lightweight and functional parts in steel cons...

...s (Fig.1). One of the company’s main focal points of development involves safety components for the automotive industry. Unlike molded components, that usually feature on the outside of a device, the safety components made from the PU material Bayfill EA (manufacturer: Bayer MaterialScience) perform their function hidden away in the background: They are used as impact absorbers in motor vehicles (for example in bumpers for pedestrian protection, as head impact protection in car headlining or as ...

...phase, fills the space between molded skin and carrier (while compensating for tolerances), and by the end of reaction time forms a stable sandwich – the instrument panel blank that can be removed from the open mold. The latest generation of Bayfill semi-hard foams is capable of reducing the foam molded skin’s density of 150 kg/m³, which already seems quite low, to only 120 kg/m³ without entailing any disadvantages somewhere else. The significance of this approx. 20 % lighter version is amplifie...
