Hydrogenated nitrile pa'u (HNBR po'o le HSN) o le oloa o le hydrogenation ma le saturation o le carbon-carbon fusi lua i le mole mole filifili o nitrile pa'u, o lea e taʻua foi maualuga saturated nitrile paʻu.

Fluoroelastomer o se polymer elastomer synthetic o lo'o i ai atoms fluorine i luga o kaponi atoms o le filifili autu poʻo le filifili itu. O le faʻaofiina o atoms fluorine e maua ai le paʻu e sili ona lelei le vevela, faʻamaʻi faʻamaʻi, faʻamaʻi suauʻu, faʻamaʻi faʻamaʻi ma le malosi o le ea, ma e faʻaaogaina lautele i le vateatea, vaalele, taʻavale, suauu ma meafale.

Ethylene propylene pa'u o se pa'u gaosia ma ethylene ma propylene o le monomer autu, e tusa ai ma le tuufaatasiga eseese o le monomer i le filifili mole, o loʻo i ai binary ethylene propylene rubber (EPM) ma le tertiary ethylene propylene rubber (EPDM), E masani ona faʻaaogaina i vaega taʻavale, mea e le susu mo le fausiaina, vevela ma uaea faʻapipiʻi faʻapipiʻi. mea faaopoopo ma isi oloa.

Zinc oxide ose vaila'au fa'aletino ma le fua fa'atatau kemikolo ZnO, ose oxide o le zinc. E le mafai ona solu i le vai ma solu i acids ma faavae malolosi. Zinc oxide o se vailaʻau faʻapipiʻi masani ma e faʻaaogaina lautele i le paʻu faʻapipiʻi.
