METHOD OF PROCESSING HIGH-MODULUS POLYETHYLENE

摘要

This invention aims at facilitating machining such as cutting, boring or the like, of high-modulus polyethylene by utilizing thermal properties thereof. In accordance with the method of the present invention, high-modulus polyethylene is heated to a temperature higher than the melting point of crystalline fibrils thereof before machining so that the heated portion of the polyethylene returns to the state before super-drawing and is easy to machine. Accordingly, a fabrication such as cutting, boring or the like can be carried out easily.
