A novel process for the preparation of flexible molded articles, such as head-end insulators for rocket casings, which are exposed to extremely high temperatures. The articles are cold-molded from shreds, discs or strips consisting of asbestos fibers and floats impregnated with a substantially uncured elastomeric binder comprising a carboxyl-terminated polybutadiene polymer.
