PROCESS FOR MOLDING FIBER-REINFORCED THERMOPLASTIC POLYMER ARTICLES

Inorganic fiber-reinforced thermoplastic articles are produced from precisely proportioned feed mixtures of particles of thermoplastic polymer, a polymer modifier and inorganic fiber bundles supplied, under specified conditions, directly to an injection molding apparatus. The articles exhibit except...

Beschreibung
Zusammenfassung:	Inorganic fiber-reinforced thermoplastic articles are produced from precisely proportioned feed mixtures of particles of thermoplastic polymer, a polymer modifier and inorganic fiber bundles supplied, under specified conditions, directly to an injection molding apparatus. The articles exhibit exceptionally superior heat deflection temperature compared to articles produced from feeds which are precompounded prior to injection molding. On produit des articles thermoplastiques renforcés par des fibres inorganiques à partir de mélanges contenant des doses précises de particules d'un polymère thermoplastique, d'un modificateur polymère et de faisceaux de fibres inorganiques, que l'on introduit, dans des conditions déterminées, directement dans une installation de moulage par injection. Les articles obtenus présentent une température de déformation à chaud très supérieure à celle des articles dont les composants sont mélangés avant le moulage par injection.
