MOP multiaxially oriented polymer structure by homoepitaxy

总结: Process for the formation of bi- or multi-axially oriented polymer structures. This allows a thick-independent homogeneous biaxial orientation us thus a significant biaxial mechanical reinforcement of polymers, such as isotactic polypropylene (iPP). Possible applications are heavy-duty lightweight panels or profiles.

技术优势: simple manufacturing process
extremely stiff and solid plates and profiles

技术应用: 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.

详细技术说明: A new process for the formation of bi- or multi-axially oriented polymer structures has been developed. In this process, the polymer is firstly crosslinked low, then melted and at last crystallized in the stretched state. As a result, a part of the crystals formed parallel to the direction of elongation while another part crystallizes approximately perpendicular to it (homoepitaxy). The degree of biaxial orientation can be controlled over the extend of stretching during crystallization.
