...pening. The roof module consists of a coextruded, in this case, grained black film that is inserted into the lower part of the foaming mould. The film is manufactured by Hagedorn in Lingen/Germany. The glass-fibre-reinforced PUR foam (grade: Elastoflex; manufacturer: Elastogran) is applied to the film by means of long fibre injection. The textile, located on the upper part of the foaming mould, is directly foamed as well. Typical cycle times, including curing of the foam after the mould has been...

...am material. Together with its development partners Sommer Allibert and Heidel, Lotte/Germany, they succeeded in series production of in-mould foamed whole door sides (Fig. 1) with PUR semi-hard foam for the DaimlerChrysler C-class. The foam system Elastoflex E 3301/4 M is particularly suitable for use in the new procedure because of its outstanding flow qualities. High durability and minimal emissions were further requirements for application in the automobile interior. Elastoflex E is a two co...

A wide range of products are available for leather and textile finishing, e.g. Lurapret, Lugafast and Steron, as well as Luquafleece with superabsorber for moisture regulation (Fig.1). Future inn...

...pace with a life-sized doll. "Everything in a seat": this was the motto adopted by Recaro for the design of a car seat (Fig. 6) with materials from BASF and Elastogran. Alongside the familiar Elastollan (TPU) and Elastoflex grades (PU flexible molded foam), use was also made of a new PU creation with the designation Steron – a microporous PU artificial leather – developed by inventor Philipp Schaefer. For the production of Steron, an aqueous formulation of pigmented polyurethanes is firs...

Design Freedom for Seat Elements With its both flexible and elastic properties, Elastoflex I delivers remarkable sitting comfort. These properties can also be varied to suit the requirements of the application. The PU system has a pleasant feel and displays good skin formation while also being highly abrasion-resistant and long-lasting. Incidentally...

In this bicycle, not only engineering plastics such as Ultradur, Ultramid and Ultraform but also polyurethanes such as Elastollan and Elastoflex and foams such as Infinergy, Neopolen and Kerdyn have been used in a hitherto unaccustomed application. Designers will find numerous stimuli for new ideas here – one example is the maintenance-free, low-wear all-plastic pedal, which operates without bal...

It is primarily aimed at automotive interior applications and has already proven itself in the Elastoflex semi-rigid system for series-production instrument panels. After the CAD model of the component and a new material description of the semi-rigid system have been generated, a filling simulation is performed. It flags problems in the design and manufacture of th...

To facilitate simulation of other foams, particularly the BASF semi-rigid and integral skin foams Elastoflex E and Elastofoam I for automotive interiors, these kinetic models have been expanded and adapted to the relevant products. By using them, it is possible to successfully predict the progress of the reaction and density development according to th...
