Abstract

Chimie du pétrole. Les compositions consistent en un bitume, un caoutchouc thermoplastique, des particules finement divisées d'un caoutchouc non thermoplastique, un agent gonflant chimique sensible à la chaleur et un agent vulcanisant du caoutchouc thermoplastique. Le chauffage d'une telle composition dans un moule provoque à la fois la vulcanisation du caoutchouc thermoplastique et le gonflement en une mousse possédant des propriétés améliorées de résistance à la compression. Plaques et feuilles pour tapis isolants de véhicules et de bâtiments.Petroleum chemistry. The compositions consist of a bitumen, a thermoplastic rubber, finely divided particles of a non-thermoplastic rubber, a heat sensitive chemical blowing agent and a thermoplastic rubber vulcanizing agent. Heating such a composition in a mold causes both the vulcanization of the thermoplastic rubber and the swelling into a foam having improved compressive strength properties. Plates and sheets for insulating mats for vehicles and buildings.
