Bayer Exhibit Innovative Applications at Composites 2005

20 October 2005

Bayer Material Science showcased a number of innovative applications along with displaying the benefits of polyurethane RIM technologies at Composites 2005.

“Composites 2005 is a tremendous opportunity for attendees to see for themselves the inherent benefits of working with polyurethane RIM technologies,” said Harry George, business manager, Specialty RIM Group, Bayer MaterialScience. “The wide variety of products on display in our booth (#1101) will reflect the design flexibility, excellent appearance and durability of products moulded using RIM technologies in general, and Bayer polyurethanes, in particular.”

Examples of products and applications on display were:

Premium Fiberglass Doors with PÜR-Fiber Technology from JELD-WEN
The skins of these doors are molded from a customized formulation of polyurethane materials from Bayer MaterialScience. The skins of the doors are formed using long fibre technology, in which long glass fibres are injected along with polyurethane resin in a one-step process. To complete the door manufacturing process, JELD-WEN laminates the composite door skins to a polystyrene core and wood edge frame.

Elson Neo Lumber FFU (Fibre Reinforced Foamed Urethane) from Sumika Bayer Urethane Co. Ltd.
It looks like wood and has all of the positive attributes of wood, but a new material that incorporates a Baydur composite system from Bayer offers clear advantages to wood for many applications, including railway ties. Unlike natural wood, the composite does not lose its favorable mechanical properties. Good resistance to hydrolysis, greases and oils makes the material reliable, even when exposed to long-term weathering.

Roush Focus Fascia
Moulded from Bayer’s Bayflex XGT 50 polyurethane RIM system, the front fascia of the dynamic, bold Roush Focus offers reduced weight without sacrificing part strength and durability. RIM technology enables moulder EPW to mould large parts with complex geometries while also achieving economies of scale by utilizing lower-cost tooling.

Sun Shade from the 2005 Toyota Avalon
Toyota Avalon passengers will benefit from an innovative sun shade formed from Bayer’s Baypreg F composite, a two-component polyurethane system that produces high strength, extremely lightweight and rigid moulded composite parts.

Reaction Injection Moulded Windmill Blade
Under a grant from the U.S. Department of Energy’s (DOE) Energy Efficiency and Renewable Energy Program, a team of researchers and industry partners are designing a 7.5-meter reaction injection moulded windmill blade comprised of a rigid carbon-fibre spar covered by skins moulded from Bayer’s Bayflex XGT-100 polyurethane RIM system. According to the principal investigator on the project, the proposed mould may well be the longest RIM mould ever attempted.

Railway Ties Made From “Polyurethane Wood”
It looks like wood and has all the positive attributes of wood, but a new material that incorporates a Baydur composite system from Bayer MaterialScience offers clear advantages to wood for many applications, including railway ties. The composite material, Elson Neo Lumber FFU (Fibre Reinforced Foamed Urethane), is reinforced with long glass fibres and produced by Sumika Bayer Urethane Co. Ltd., a subsidiary of Bayer MaterialScience AG.
