Low viscosity addition
Vol. 19, #2, June 1992
When incorporating low viscosity additives into a polymer that does not readily absorb the liquid in the unfluxed mix, some options are:
1.) Feed the liquid downstream after the polymer has been fluxed.
2.) This can be done in several stages if the liquid amount is too high for one stage incorporation, i.e. slippage results.
3.) When extruding colored products, for more efficient changeover, use the whim to black color wheel.
