E tatau ona fa'aogaina le fa'apipi'i e lua-vaega i totonu o le vaitaimi talafeagai pe a uma ona tu'u i totonu RE.
O le umi o le vaitaimi talafeagai e le gata e fesoʻotaʻi ma le polymer anotusi o le faʻapipiʻi, ae faʻapea foi isi vaega talafeagai (pei o resin, antioxygen, plasticizer, solvent, etc.
A latalata i le vaitaimi talafeagai, e masani lava o ni nai itula poʻo se tasi aso faigaluega, faʻapipiʻi e sili atu ona faigata ona faʻaogaina, ma vave faʻatupu le viscosity.
Mulimuli ane, E avea ma jelly e le mafai ona suia. 100 fa'apipi'i lelei, Hydroxyl polyurethane (Polyurethane account mo le 20%), RE dose 4-7. Chloroprene pa'u (Rubber account mo le 20%), RE faia 4-7.
