Patent

CA 2252618

This invention concerns a mixture of a first component selected from talcs and a second component selected from feldspars, nephelines and nepheline syenites, wherein the ratio of the first component to the second component provides an enhanced abrasiveness property. The invention further relates to an antiblock agent made from such mixture. This mixture provides favorable optical properties when used in a polyolefin film. This invention also relates to a polyolefin resin composition having the mixture therein, as well as to films made with such.

Mélange d'un premier composant sélectionné dans les stéatites, et d'un second composant sélectionné dans les feldspaths, néphélines et syénites néphélitiques, dans lequel le rapport entre le premier et le second composant permet d'obtenir une propriété abrasive accrue. L'invention porte également sur un agent antiadhérent produit avec un tel mélange. L'orsqu'il est utilisé dans un film de polyoléfinique, ce mélange confère de bonnes propriétés optiques. L'invention concerne en outre une composition de résine polyoléfinique contenant ce mélange ainsi que des films fabriqués avec ce dernier.
