The c-axis longitudinal phonon velocity in polyethylene is approximately 17 km/s.
“The c-axis velocity of the longitudinal polarization is vc ~ 17 km s−1 (refs. 38–40).”
From Origin of high thermal conductivity in disentangled ultra-high molecular weight polyethylene films: ballistic phonons within enlarged crystals (2022) · cites this paper as [38]
Phonons with such long mean free paths are likely from the longitudinal acoustic branch owing to its high group velocity of about 16-17 km s−1.
“Phonons with such long MFPs are likely from the LA branch owing to its high group velocity vc ~ 16−17 km s−1 (refs. 38–40,42,67).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
