produit chimique stable

OBS: Les chlorofluorométhanes ont la réputation d'être des produits chimiques extrêmement stables.

CONT: Freons are exceptionally stable chemicals toward almost anything normally encountered in the environment or put into aerosol cans; they are popular among aerosol manufactures because they have essentially no odor and impart no flavor. For the same reasons, their potential for harm went unsuspected for years.
