ROLLER-DIE EXTRUSION OF POLYMERS

摘要

61968-725 PROCESS FOR OBTAINING ULTRA-HIGH MODULUS PRODUCTS A polymer is solid-state deformed under pressure through the rollers of an extrusion rolling die, at a temperature near but below its crystalline melting point, while controlling the extrusion rate and the rate of rotation of the rollers so that the rake of extrusion of the polymer is substantially the same as the rate of rotation of the rolling die surface.
