polyéthylène linéaire

OBS: PEL; PE-L : abréviations non officielles; ne pas les utiliser seules, pour éviter tout risque de confusion.
PHR: Polyéthylène linéaire à basse densité, à faible densité, de faible densité, ductile, faible densité, multicouche, ramifié, réticulé.

CONT: The density of polyethylene and other thermoplastic polymers is affected by the shape and spacing of the molecular chains; low-density materials have highly branched and widely spaced chains, whereas high-density materials have comparatively straight and closely aligned chains. Polymers of the latter type are called linear.
OBS: LPE: This might be an in-house or a non-recognized abbreviation; not to be used alone, to avoid any risk of confusion.
