The invention enables a thickness-independent homogeneous biaxial orientation and thus a considerable biaxial mechanical reinforcement of polymers such as, for example, isotactic poly(propylene) (iPP). Possible technical applications are highly loadable lightweight boards or profiles.
- simple manufacturing process
- extremely stiff and solid plates and profiles
An European patent application for this invention has been filed. As an exemplary embodiment, iPP was oriented multiaxially by crystallization upon uniaxial stretching. Detailed experimental data are available. On behalf of the TU Dortmund, PROvendis is seeking a licensee for the new technology.
