Moulding material, especially for extrusion compression moulding, comprises particles containing fibres with inner and outer sheath of different viscosity polymers

摘要

The granular particles contain fibres with an inner sheath of low viscosity polymer and an outer sheath of a relatively high viscosity polymer. Granular particles comprise a thermoplastic polymer and fibres which extend in the particle length direction and have a length (approximately) equal to that of the particle. The fibres are provided with an inner sheath comprising a low viscosity first polymer (composition) and an outer sheath comprising a second polymer (composition) with a viscosity higher than that of the first polymer. Independent claims are also included for the following:LISTN>Method for preparing the particles by crushing the fibres and mixing them with the thermoplastic polymer; and Moulded articles made from the granular particle material.LISTN>.
