O le a le UV-144 CAS 63843-89-0?

UV-144 paʻepaʻe i sina paʻu samasama, maualuga-faatinoga NOR ituaiga faʻalavelave amine malamalama stabilizer, talafeagai mo le alamanuia ufiufi paʻu. O mea fa'amausali amine fa'alavelave fa'atasi ma amio fa'aantioxidant phenolic fa'alavelave e mafai ona fa'aitiitia ai le ta'e ma le leiloa o le iila, fa'ateleina le ola tautua o ata vali.

Fa'atatauga

UV-144 maualuga-faatinoga NOR ituaiga taofia amine malamalama stabilizer, talafeagai mo le alamanuia ufiufi paʻu. O mea fa'amausali amine fa'alavelave fa'atasi ma amio fa'aantioxidant phenolic fa'alavelave e mafai ona fa'aitiitia ai le ta'e ma le leiloa o le iila, fa'ateleina le ola tautua o ata vali. I le taimi lava e tasi, o loʻo i ai le meatotino o le faia o paʻu paʻu felaʻuaʻi ma molia, faʻaleleia le fua o le paʻu paʻu. E masani ona faʻaaogaina i paʻu paʻu, uʻamea uʻamea, paʻu taʻavale, ma isi.
