O loʻo i ai uiga o le punou malosi lelei, lelei faʻataʻitaʻiga faʻataʻitaʻiga, sili ona lelei le faʻatinoga o le ozone, faʻasolosolo matua, vevela vevela, suauʻu teteʻe, ofuina teteʻe ma isi. Chloroprene synchronous fusipa'u e fa'aaogaina lautele i ie, ta'avale, alava vaila'au, sikaleti, fai pepa, lomitusi, masini vaila'au ma meafaigaluega; I tausaga talu ai nei, o loʻo faʻateleina le faʻaogaina o metallurgy, uʻamea ma uʻamea, masini faʻafomaʻi manaʻomia.

E tusa ai ma meafaitino, e mafai ona vaevaeina le fusipaʻu faʻatasi i le paʻu neoprene ma le maea fiber fusipaʻu faʻatasi, polyurethane ma le uaea uaea fusi faʻatasi. E tusa ai ma foliga o nifo, e masani ona vaevaeina i nifo trapezoidal ma nifo arc. E tusa ai ma le faatulagaga o nifo, e mafai ona vaevaeina i le tasi itu nifo synchronous fusipaʻu ma lua-itu nifo synchronous fusipaʻu.

O le fusipaʻu e sili ona lelei le faʻafefeteina, faʻalautele laʻititi, malosi maualuga, ae o loʻo i ai foʻi le suauʻu, faʻafefe vevela, faʻamaʻi matua, tetee atu i le osone, teteʻe ma isi mea lelei. O le fusi faʻatasi o loʻo i ai nei e sili atu i le 30 faʻataʻitaʻiga, sili atu i le 1000 faʻamatalaga, ma le lagolagoina o le uili fusi faʻatasi, faʻaopoopo i faʻataʻitaʻiga masani, ae faʻapea foʻi mo tagata faʻaoga e mamanuina ma gaosia faʻamatalaga faʻapitoa o le fusi faʻatasi, e fetaui ma manaoga faʻapitoa o tagata faʻaoga.

Na faia e Annai ituaiga uma o faʻasologa o fusi faʻatasi, faʻataʻitaʻiga faʻapitoa: 2M, 3M, 5M, 8M, 14M, 20M, H, L, MXL, P2M, P3M, P3M, P5M, P8M, P14M, S2M, S3M, S4.5M, T5M, S4.5M, S5M, S5M, S5M T10, T20, XH, XL, XXH ma isi.
