FOLASAGA

O le DonSpray504 o le pulupulu faʻafefiloi polyols, faʻafefe o le 245fa nai lo le HCFC-141B, e tali atu i le isocyanate e maua ai le foam e sili ona lelei, e pei ona taua i lalo,

1) sela lelei ma tutusa

2) conductivity vevela maualalo

3) atoatoa mumu tetee

4) lelei maualalo-vevela tulaga mautu.

E faʻatatau i ituaiga uma o faʻainisinia faʻamalama vevela e faʻaogaina ai le tekinolosi faʻafefe, e pei o potu malulu, ulo, paipa tetele ma le fausiaina o metope ma isi.
