Retroreflective articles for life saving devices at sea are described comprising a layer of a pressure-sensitive adhesive made using a solvent-free hot melt process which employs as starting material a tackified non-thermoplastic hydrocarbon elastomer. The process employs a continuous compounding device that has a sequence of alternating conveying and processing zones.

La présente invention concerne des objets réfléchissants pour équipement de survie en mer. Ils comportent une couche d'adhésif collant sous l'effet d'une pression fabriqué grâce à un procédé de thermofusion sans solvant selon lequel on utilise, comme produit de départ, un élastomère d'hydrocarbure non thermoplastique et rendu collant. Ce procédé est mis en oeuvre au moyen d'un appareil à mélanger en continu qui a une suite de zones alternées de transport et de traitement.
