MAJORIS G407 is a special long glass fibre reinforced polypropylene grade, for injection moulding and extrusion. The long glass fibres, chemically coupled to the polypropylene matrix, are providing with outstanding mechanical properties. This product is UV stabilised. MAJORIS G407 is available both in natural (MAJORIS G407) and black (MAJORIS G407-8229). Other colours can be provided on request. APPLICATIONS MAJORIS G407 is intended for injection moulding of highly demanding technical applications. The excellent properties of MAJORIS G407 make it suitable for: Electrical components, automotive parts, interior, exterior and under the bonnet, structural furniture parts, load bearing, demanding components for various engineering sectors. MAJORIS G407 can, in many of these applications, substitute other engineering plastics or metal alloys.&& |
