Description
Procédé pour la production de corps creux transparents comme le verre, à parois minces, et, le cas échéant, de feuilles, par extrusion-soufflage de matières thermoplastiques cristallisables, autres que le polyéthylène, en parti- culier de polyamides, caractérisé en ce qu'on insuffle dans ces matières thermo- plastiques, au cours de leur transformation en corps creux, un mélange d'air - ou d'un autre gaz - avec une vapeur se condensant rapidement.
**ATTENTION** fin du champ DESC peut contenir debut de CLMS **.
Process for the production of transparent hollow bodies like glass, with thin walls, and, where appropriate, of sheets, by extrusion blow molding of crystallizable thermoplastics, other than polyethylene, in particular of polyamides, characterized in that During their transformation into hollow bodies, these thermoplastics are blown with a mixture of air - or of another gas - with a rapidly condensing vapor.
** ATTENTION ** end of DESC field can contain start of CLMS **.
