The disclosure relates to a calibrator (100) including a first plate opposing a second plate, the first plate having a first foam-expansion surface adjacent to a first anti-static surface (102), the second plate having a second foam-expansion surface adjacent to a second anti-static surface, wherein the first foam- expansion surface and the second foam-expansion surface are aligned to form a foam-expansion region (101), and wherein the first anti-static surface and the second anti-static surface are aligned to form an anti-static region. The disclosure also relates to a method of producing a polyetherimide foam (103), the method including passing a liquid polymer mixture comprising a polyetherimide through the calibrator (100). |
