...PS and LCP are able to withstand temperatures of over 200°C. For the system integration and in the whole field of power management, the ideal solution is to use materials such as PBT (e.g. Celanex) and long strand-reinforced thermoplastics (e.g. Celstran). The Future Has Already Begun Hydrogen-powered buses are already being tested on the roads. In passenger cars, too, fuel cells have already covered hundreds and thousands of test kilometres, for example in the A-Class from DaimlerChrysler...

There are also polyphenylene sulphide (PPS; grade: Fortron), ultra-high molecular weight polyethylene (PE-UHMW; grade: GUR), polybutylene terephthalate (PBT; grade: Celanex) and long fibre reinforced thermoplastics (LFT; grade: Celstran). Conclusion The proposed European drinking water regulations not only lead to changed market conditions, but also require raw material manufacturers to give their market partners every possible support. This goes beyond the pure supply of conforming raw ma...

Special Safeguarding the Future through Process Integration Multi-component Technique. Multi-component injection moulding has gained enormous importance over the last fifteen years. This is due both to the development of sophisticated products and to the efforts being made generally to economise. The combination of well-known processes, such as sandwich moulding with injection-compression moulding or the fluid injection technique, offers fresh possibilities for lowering costs and creating inn...

Comparable approaches were also presented by Ticona (Celstran LFT) and DuPont (Superstructural thermoplastics). DuPont favours polyamide-based matrix systems which, with their high stiffness and mechanical strength coupled with a very high creep and fatigue resistance, can be used for load-bearing automoti...
