METHOD FOR THE PRODUCTION OF HIGH TENACITY POLYOLEFIN SHEET
摘要
A process for the production of virtually full density polyolefin suitable for further processing by drawing to form a high tenacity, highly oriented polyolefin sheet comprising: a) feeding a metered amount of polyolefin powder into the nip between two heated calender rolls; b) rolling the powder through the nip until a coherent sheet of polyolefin sheet is produced: and c) once a coherent polyolefin sheet exits the nip adjusting the temperature in the nip to obtain specific tensile and elongation properties. Apparatus for the performance of such a process is also described Such a process not only eliminates the need for a separate and costly compaction step, but yields a coherent polyolefin sheet that is ready for drawing in accordance with prior art processes for the production of a high tenacity, highly oriented polyolefin sheet having a high heat of fusion.
