Abstract

Des compositions de résine phénolique novolaque sont transformées en granules à mouler en homogénéisant la composition au-dessus du point de fusion de la résine, en calandrant en 10, 12 la composition homogénéisée pour la transformer en une feuille cohérente 14, en laminant la feuille entre deux rouleaux 16, 18, dont l'un au moins porte des dents, pour produire une feuille cohérente gaufrée 14a, en brisant la feuille gaufrée, en séparant les granules ayant sensiblement la forme et la dimension du gaufrage, en enrobant la granules avec un composé phénolique, et en traitant thermiquement les granules enrobés par circulation d'un courant de gaz inerte à une température ne dépassant pas 130 degrés C. Les granules ainsi obtenus s'écoulent librement, n'ont pas tendance à libérer de la poussière, et conviennent particulièrement pour le moulage par injection.
