Li-catalyst tsa polyurethane, tse kang MXS-6 (DC-193), li bohlokoa tlhahisong ea li-sole tsa polyurethane (PU), e leng lejoe la bohlokoa indastering ea lieta. Li-catalyst tsena, ho kenyeletsoa le li-surfactant tsa silicone tse tloaelehileng indastering, tse sebelisoang ka kakaretso, li bohlokoa bakeng sa ho theha lits'ebetso tse thata tsa foam ea polyurethane, haholo-holo tlhahisong ea lieta. Li bapala karolo ea bohlokoa ho ntlafatseng thepa ea li-sole tsa PU, li etsa hore li lokele mefuta e fapaneng ea lieta ho kenyeletsoa lieta tse tloaelehileng, lieta tsa polokeho le lieta tsa lipapali.
Mosebetsi o ka sehloohong oa li-catalyst tsa polyurethane ke ho potlakisa karabelo ea lik'hemik'hale lipakeng tsa isocyanate le polyols, tse etsang polyurethane. Karabelo ena e bohlokoa ho theheng sebopeho sa foam sa li-sole tsa PU, e li fa thepa e ikhethang joalo ka ho tšoarella, ho tenyetseha le ho monya ha shock. MXS-6 (DC-193), kaha ke silicone surfactant, e thusa ho tsitsisa sebopeho sa foam, e netefatsa boleng bo tsitsitseng le ts'ebetso ea li-sole tsa PU.
Lieta tse sa reroang, lieta tsa polyurethane li fana ka boiketlo le ho tenyetseha ho sa bapisoeng. Karolo ea catalyst ho netefatseng hore sebopeho sa foam se boreleli ebile se tsitsitse e fetolela lieta tse fanang ka ho tenyetseha ho kang ha letlalo le bokaholimo bo boreleli. Sena se fella ka lieta tse sa phutholohang feela bakeng sa ho aparoa nako e telele empa hape li khahlisa botle, li khotsofatsa setaele le litlhoko tsa boiketlo tsa baapehi ba lieta tse sa reroang.
Bakeng sa lieta tsa polokeho, ho tiea le boleng ba ho monya litšepe tsa polyurethane ke tsa bohlokoa. Li-catalyst li netefatsa hore lieta tsa PU li na le sebopeho sa foam se tiileng se khonang ho mamella maemo a thata le ho sireletsa maoto a moapari.

Tšireletso ena, hammoho le ho tšoarella ha lieta tsa PU, e etsa hore lieta tsa polokeho li tšepahale ebile li tšoarelle nako e telele.
Lieta tsa lipapali li hloka litšobotsi tse ntle tsa ts'ebetso, tse ntlafatsoang haholo ke li-catalyst tsa polyurethane. Ho tenyetseha le ho khomarela tse fanoang ke lieta tsa PU li bohlokoa bakeng sa lieta tsa lipapali, li fana ka tšehetso e betere le ho fokotsa tšusumetso maotong nakong ea mesebetsi e matla.MXS-6 (DC-193)etsa bonnete ba hore maoto a boloka sebopeho le ts'ebetso ea 'ona, esita le tlas'a maemo a thata a ts'ebeliso ea lipapali.
Ho feta moo, lieta tsa polyurethane tse hlahisoang ka li-catalyst tsena li bobebe, li eketsa boiketlo le ts'ebetso ea lieta.
