The nucleation of gas bubbles in extrusion foaming of high-pressure polyethylene is considered. Experiments show that undissolved gas microbubbles in the plastic recycling machines perfect solution is being foamed might have a significant effect on the quantity density of skin pores in the foam. A straightforward model for estimating the true number density of supercritical nuclei is proposed. The effect of the right time of mixing of gas and polymer in the extruder, the talc concentration, and the geometric attributes of the nozzle on the number density of skin pores in the foam is usually analyzed.
