Patent CA-2267417-A1 (CA)
Inventor: BONNER MARK JAMES
IPC: D04H1/54
Filed: 1997-10-06
Abstract: A polyolefin plaque is made by hot compaction of an assembly of fibres of the oriented polymer. It has been found to be beneficial to subject the fibres to a prior cross-linking process. Hot compaction is then less temperature-sensitive and produces plaques with excellent hot strength properties. Preferably the fibres have been subjected to prior stages of irradiation and annealing, both in a non-oxidising environment, for example acetylene.
