6630 (DMD) polyester ata polyester alava e le lalagaina malu tu'ufa'atasi mea vevela vevela vasega B o se tolu- apaapa vaivai mea insulation tu'ufa'atasi, faia i polyester ie lē lalagaina, polyester ata, polyester ie lē lalagaina ( DMD) tuufaatasiga, le fa'apipi'i fa'aaogaina e leai se acid, vevela, e iai mea fa'ainisinia ma eletise lelei, o le ie e le o lalagaina o le polyester o lo'o i ai le malosi o le adsorption, e mafai ona fa'afefe resin pe a fa'asusu. Faʻaaogaina mo le vaeluagalemu ma vaʻavaʻa-vaega insulation i le maualalo-voltage motors, poʻo le faʻaaogaina e pei o le interlayer insulation i transformers, o le stiffness mea e tele, ma e talafeagai mo masini ese-laina faagasologa.
6630 (DMD) Vasega B pepa fa'amama e tatau ona teuina i totonu o se potu malulu, mamago ma mama (i lalo ole 40°C) si'osi'omaga. I le taimi o felauaiga ma le teuina, e tatau ona gauai atu i le afi, susu, mamafa ma le puipuiga o le la. O le taimi e teu ai i le vevela o le potu e 12 masina, ma e mafai lava ona faʻataʻitaʻiina pe a uma ona pasia manaʻoga faʻapitoa o le taimi e teu ai.
