Title (EN) THERMOPLASTIC VULCANIZATE COMPOSITIONS
(FR) COMPOSITIONS DE VULCANISAT THERMOPLASTIQUE
Abstract:
(EN) In methods for forming thermoplastic vulcanizates, and thermoplastic vulcanizates formed by such methods, a masterbatch comprising one or more additives in a carrier resin comprising propylene- or ethylene-based copolymer is added to the thermoplastic vulcanizate formulation. The resulting thermoplastic vulcanizate may additionally be passed through a 200 mesh or finer screen and thereafter extruded. The thermoplastic vulcanizates may exhibit increased extrusion throughput rates and enhanced surface smoothness.
(FR) Cette invention concerne des procédés de formation de vulcanisats thermoplastiques, et des vulcanisats thermoplastiques formés par lesdits procédés, qui consistent à ajouter un mélange maître comprenant un ou plusieurs additifs dans une résine de base comprenant un copolymère à base de propylène ou d'éthylène à la formulation de vulcanisat thermoplastique. Le vulcanisat thermoplastique obtenu peut en plus être criblé par passage dans un crible à mailles de 200 mesh ou plus fines et ensuite extrudé. Les vulcanisats thermoplastiques selon l'invention présentent des vitesses d'extrusion en hausse et une lisseur de surface améliorée.
