A method of manufacturing a finished product from exfoliated vermiculite particles includes the steps of impregnating the exfoliated vermiculite particles with an impregnating composition consisting of a mineral oil and a liquid thermosetting resin, optionally with a catalyst therefor. Thereafter, the exfoliated vermiculite particles are compressed with heating to allow the mineral oil to infuse the exfoliated vermiculite particles and to polymerise the thermosetting resin to form the finished product.
L'invention se rapporte à un procédé de fabrication d'un produit fini à partir de particules de vermiculite expansée. Ce procédé comporte les étapes suivantes qui consistent à imprégner lesdites particules de vermiculite expansée d'une composition d'imprégnation contenant une huile minérale et une résine thermodurcissable liquide, éventuellement accompagnée d'un catalyseur. Les particules de vermiculite expansée sont ensuite comprimées grâce à de la chaleur en vue que l'huile minérale pénètre dans lesdites particules et que la résine thermodurcissable se polymérise et ce, aux fins de former le produit fini.
