BASF : thermoplastic specialties everywhere

News International-French

11 Oct 2012

Engineering plastics, polyurethanes and masterbatch preparations are once again the major topics of this year's BASF exhibit at the international exhibition for plastics processing. The company is displaying its new products for the plastics processing industry.

Garden tools with long glass fiber reinforcement
Ultramid® Structure is being used as a structural material not only in the first prototypes of an all thermoplastic wheel rim: The new plug-in garden tool system from the company Freund Victoria Gartengeräte is also benefiting from it. It employs a connecting piece made from this high strength long glass fiber-reinforced polyamide specialty from BASF. As with other components made from Ultramid Structure, the unusual inner structure created by the backbone of long glass fibers can be demonstrated by ashing the part.


Automotive: Thermoplastic specialties and composites
First high-volume application of heat-resistant Ultramid Endure
The highly heat-stabilized Ultramid® Endure, which is suitable for use on turbocharged engines, is of interest to the automotive industry. The first high-volume application of this engineering plastic will be on exhibit at the BASF booth: This polyamide specialty is now being used for mass production of an air intake application on a large family of engines. Here, the exceptional heat aging resistance of Ultramid Endure is a major benefit: The material has a continuous service temperature of 220°C and can withstand peak temperatures of 240°C.


Full steam ahead: Composites
Efficient, lightweight designs for structural body and chassis components in the future require the use of composite materials and composite parts. In this field, BASF will be exhibiting two automotive applications showing different utilization levels: The seat pan used in the Opel Astra OPC is already in production: it is the world's first seat pan used in a production vehicle and is manufactured from thermoplastic laminates with continuous fiber reinforcement. Two Ultramid (PA) grades from BASF come into play here, one as the impregnating material, the other as the overmolding material. With its stiff yet thin walls, the seat pan is about 45% lighter than its predecessor.


A convertible roof module illustrates a different approach that is available only in the form of a concept study at present: BASF and EDAG have developed it jointly to explore the possibilities offered by resin transfer molding (RTM) with BASF materials. The center layer of the demonstrator’s sandwich structure is a closed-cell PU structural foam based on Elastolit® D. It functions as a spacer between the carbon fiber laminate layers, provides high part rigidity and gives the roof module good insulating properties. The roof module is more than 35 percent lighter than its aluminum counterpart.


BASF has announced a cooperative effort with the carbon fiber manufacturer SGL Group with the objective of jointly developing carbon fiber-reinforced composites based on new reactive polyamides.
