Abstract: Equipment for blending a low viscosity liquid (I) (0.01-10 poise) in to a high viscosity liquid (IIe (100-10,000 poise) divides the flow of (IIe into several treams of relatively small cross-section flowing past porous walls for admitting (I) from a region of higher pressure. For general use, but esp. for adding blowing agent, lubricant, stabilisers etc. directly to polymer melts. Attains a high degree of distribution of (I) in (II) in the initial mixing zone, reducing the work subsequently required for homogenisation of the mixt.
