Polyurethanes Glass-reinforced

Different core materials are used. They include foam, honeycomb core (plastic, paper, aluminum, etc.), ribs, balsa wood, filler spacers, corrugated sheet spacers, etc. Materials such as polyurethane foam, cellulosic foams, and polystyrene foams are widely used as core materials. Plastics, such as glass-reinforced polyester, are frequently used as the skins for panels. Different skin materials are used such as metallic skins alone or in conjunction with plastic skins.

The growth of these materials is reflected in the number of polymers which are being glass reinforced. These include polypropylene, polystyrene, styrene acrylonitrile, nylon, polyethylene, acrylonitrile-butadiene-styrene, modified polyphenylene oxide, polycarbonate, acetal, polysulfone, polyurethane, poly (vinyl chloride), and polyester. In addition, the reinforced thermoplastics available now include long-fiber compounds, short-fiber compounds, super concentrates for economy, a combination of long and short fibers, and blends of polymer and fibrous glass.

For this case study, a vertical body panel such as that being molded of glass reinforced polyurethane-RIM (PU-RRIM) for the Pontiac F1ero fenders and door panels was chosen. The average projected surface area for a typical fender and door panel 1s about 750 sq. 1n. and 1,000 sq. 1n. respectively. The fender was selected for this stu[Pg.16]

Castor oil-based polyurethane resin is used to obtain graphite composite as an electrode material. The 60% graphite (w/w) composite exhibits good mechanical and appropriate electric resistance and offers ease of preparation and surface renovation. The polyurethanes of soybean oil-based polyol with glass reinforced composites exhibit mechanical properties comparable with those based on petrochemical polyol. The oxidative, thermal and hydrolytic stability of soybean oil-based composites are superior to those of petrochemical polyol. All the results indicated that a polyurethane matrix based on soybean oil is a preferable alternative to petrochemical polyurethanes in glass reinforced composites. [Pg.261]

Bayer Bayflex elastomeric polyurethane reaction injection molding (RIM) is a two-component diphenylmethane diisocyanate- (MDI)-based liquid system produced in unreinforced, glass-reinforced, and mineral-Zmicrosphere-reinforced grades. They possess a wide stiff-... [Pg.201]

Moulds are made from steel, aluminium and sometimes from solid polyurethane or silicone rubber or occasionally glass-reinforced plastic (polyester or epoxy resins). For long life, case-hardened steel is very satisfactory. Air vents are recommended as OT mm (0 004 in) between horizontal mould plates. [Pg.405]

Polyurethanes in general are noted for their abrasion resistance, toughness, low-temperature impact strength, cut resistance, weather resistance, and fungus resistance. Specialty polyurethanes include glass-reinforced products, fire-retardant grades, and UV-stabilized grades. [Pg.449]

RRIM polyurethanes are an extension to Reaction Injection Moulding (RIM) which is a relatively recent, but now established, plastics processing technique. Simplified, RRIM is the inclusion of a reinforcement - short glass fibres - into one of the components used in the RIM process. However, the inclusion of glass reinforcement into one of the reactive components, usually the polyol, has meant that certain processing equipment modifications were necessary in order to handle the...

Traditionally, solid seat pans were regarded as inferior to frames with lattice springing. Improvements in polyurethane technology such as dual hardness foams have transformed the situation. Once the solid seat pan became acceptable, it was inevitable that steel should be replaced by one or other plastic material. The asymmetrical rear seat of the 1989 Peugeot 405 estate car features two pans in injection moulded glass-reinforced PP, with a variety of textile covering options (see Fig. 4.10). Other versions have followed on this theme, notably in PP-GMT. [Pg.82]
