METHOD OF PRODUCING HIGH-STRENGTH POLYETHYLENE FILM

摘要

FIELD: chemistry.SUBSTANCE: method involves applying pressure of at least 20 bar (2000 kPa) to an amount of disentangled polyethylene and temperature between the b-relaxation temperature and the melting temperature of the disentangled polyethylene T(T) to obtain a block of disentangled polyethylene, slicing a film or tape off the block of disentangled polyethylene and drawing said film or tape in a single or multi-stage drawing step at a total draw ratio of at least 1:20.EFFECT: obtaining articles of high strength using a simple technique with high cost effectiveness.6 cl
