Donspray 504 HFC-245fa basi conpositum polyolorum
INTRODUCTIO
DonSpray504 mixtio polyolorum imbre est, agentis spirans 245fa loco HCFC-141B est, cum isocyanate reflectitur ad spumam producendam quae spectacula praeclara habet, quae sunt haec;
I) denique et uniformitas cellulis
II) humilis scelerisque conductivity
III) perfecta flamma resistentia
4) Bonum humilis temperaturae stabilitas dimensiva.
Ad omnes species machinarum scelerisque velit, quae imbre technicae utitur, ut cubicula frigida, ollas, tibias magnas et metopes constructiones etc.
