PTFE's taua tele vailaʻau, vevela, susu, ma le eletise teteʻe e avea ma mea sili ona lelei i soo se taimi o oloa, meafaigaluega, ma vaega e manaʻomia ona tumau ma faʻatuatuaina e oʻo lava i faʻaoga sili ona mamafa.I le pito i luga o lenei mea, ua fa'ae'eina le uaea fa'apipi'iina o le PTFE e tulaga ese le tumau o le vevela ma le fa'asaoina o le afi lea e avea ai ma filifiliga lelei mo se lisi fa'atuputeleina o oloa, vaega, ma talosaga.
O le Polyurethane (PUR ma le PU) o se polymer e fa'apipi'i i vaega fa'alela'au fa'atasi i so'oga o le carbamate (urethane).E ui o le tele o polyurethanes o polymers thermosetting e le liusuavai pe a vevela, e maua foi polyurethanes thermoplastic.
Polyurethane polymers e masani ma masani ona fausia e ala i le taliina o se di- poʻo le polyisocyanate ma se polyol.O isocyanates ma polyols na fa'aaogaina e fai ai polyurethanes o lo'o i ai, i le averesi, lua pe sili atu vaega galue i le mole.
