  • Method for extrusion of highly viscous thermosetting material
    Patent number: 4205030
    Abstract: A method for extrusion of a highly viscous thermosetting or a thermoplastic material comprising extrusion of said material in the presence of substances diminishing external friction of the melt, at a ratio between internal and external friction values of the material melt within the range of from 1.5 to 4.0; the thermosetting material melt viscosity being ranged from 50.times.10.sup.6 to 300.times.10.sup.6 poises, while the thermoplastic material melt index being varied from 0.01 to 0.1 g/10 min.The ratio between internal and external friction values of the material melt is maintained within the above-specified range by way of incorporation, into the starting thermosetting or thermoplastic material, of certain compounds. For thermosetting materials, use is made of, e.g. zinc dialkyldithiophosphate, and for thermoplastic materials barium sulphonate is used as such a compound.
