Sep 4th, 2008 Print this article Orientation give PVC pipes an extra helping of ‘tough’By Modern Plastics Editorial Staff This manufacturer says its equipment to produce oriented vinyl (O-PVC) pipes produces an end product that provides high impact resistance, stiffness, assurance against fatigue, and good mechanical behavior under loads. Following extrusion, the pipe is oriented to modify the melt’s molecular structure so that the molecules align in the direction of the deformation. During this process, there is a transformation of the polymer’s amorphous arrangement into an organized and layered structure. O-PVC equipment can be retrofitted onto existing PVC pipe extrusion lines or the system can be performed off-line. The company’s executives will present the technology in September at the open house of extruder manufacturer Cincinnati Extrusion (www.cet-austria.com) in Vienna, Austria on Sept. 19 or Sept. 25, and also immediately thereafter at an open house of its own on Sept. 26.
