O le ā le Poly(propylene glycol) CAS 25322-69-4?

O le Poly(propylene glycol) o se polymer e foliga mai e leai se lanu i se vai samasama vaivai. E mafai ona solo i le vai (mamafa molecular maualalo) ma solvents organic e pei o aliphatic ketones ma alcohols, ae e le solo i le ether ma le tele o aliphatic hydrocarbons. E maua mai i le condensation o le propylene oxide ma le propylene glycol i lalo o le mamafa maualuga pe i le i ai o se acidic catalyst.

Talosaga

1. O fa'asologa o PPG e mafai ona solo i vaila'au fa'aola e pei o le toluene, ethanol, trichloroethylene, ma isi. O PPG200, 400, ma le 600 e mafai ona solo i le vai ma e iai ona uiga fa'asusu, fa'aleaga, fa'aleagaina, ma tete'e i siama. E mafai ona fa'aogaina le PPG-200 o se mea e fa'asalalau ai vali.

2. I mea teuteu, e fa'aaogaina le PPG400 o se mea e fa'amalie ai le tino, fa'amalūlūina, ma se mea e fa'a'asu ai le tino.

3. E fa'aaogaina le Poly(propylene glycol) o se vaila'au e tete'e ai i le foaming i vali ma suāu'u hydraulic, o se vaila'au e tete'e ai i le foaming i le fa'agasologa o le pa'u fa'apitoa ma le latex, o se refrigerant ma se coolant mo vai e fesiita'i ai le vevela, ma se mea e fa'aleleia ai le viscosity.

4. E fa'aaogaina le Poly(propylene glycol) o se vaila'au fa'afefiloi mo le esterification, etherification, ma le polycondensation reactions.

5. E fa'aaogaina le Poly(propylene glycol) o se mea e fa'asa'oloto ai, o se mea e fa'avaivai ai, o se mea fa'aopoopo mo suāu'u fa'apitoa, o se mea fa'aopoopo mo suāu'u tipi e mafai ona fa'avaivaia i le vai, suāu'u fa'ase'e, suāu'u hydraulic, mea fa'asusu vevela maualuga, ma mea fa'asusu i totonu ma fafo mo le pa'u.

6. E sili ona lelei le fa'asusuina o le PPG-2000~8000, e tete'e atu i le fa'apupuna, tete'e atu i le vevela ma le aisa ma isi meatotino;

7. E faʻaaogaina tele le PPG-3000~8000 o se vaega o le polyether tuʻufaʻatasi e gaosia ai palasitika foam polyurethane;

8. E mafai ona fa'aoga sa'o le PPG-3000~8000 pe a uma ona fa'aogaina le esterification e gaosia ai ni plasticizers ma ni lubricants;
