SIZING COMPOSITION FOR GLASS FIBRE GRANULES WITH A HIGH GLASS CONTENT

摘要

The invention relates to a sizing composition for glass fibres comprising the following components as expressed in percentages by weight of solid matter, namely: 10 to 99 % of at least one copolymer that is selected from among copolymers of vinyl acetate and ethylene or acrylic or methacrylic acid, 1 to 40 % of at least one coupling agent, and 0 to 90 % of polypropylene grafted by at least one unit derived from at least one monomer containing one or more functions that can react with the coupling agent. The glass fibres obtained are intended to be used to form glass fibre granules having a high glass content for the production of composite parts comprising a thermoplastic matrix that is reinforced with cut glass fibres by means of injection moulding.
