I-Phthalic Anhydride Polyester polyol
Lolu chungechunge lwama-polyols ikakhulukazi ama-polyester polyols anephunga elimnandi alungiselelwe i-polycondensation noma ukuguqulwa kwe-phthalic anhydride, i-diethylene glycol nezinye izinto zokusetshenziswa.Zisetshenziswa ikakhulukazi emkhakheni we-foam eqinile kanye nama-adhesives.Zinezinzuzo zephunga eliphansi, umbala ophansi, umsebenzi wokusabela okuphezulu, ukuzinza okuhle kakhulu kwe-hydrolysis, okuqukethwe okunephunga elimnandi, ukuzinza okuhle kanye noketshezi lwezinto ezihlanganisiwe, Futhi isakhiwo somkhiqizo singashintshwa ngokuvumelana nezidingo zamakhasimende.
Lolu chungechunge lwama-polyester polyols lungasetshenziswa kabanzi esiqandisini, isitoreji esibandayo, ukufafaza, amandla elanga, amapayipi ashisayo, ukufakwa kwesakhiwo kanye nezinye izindawo zokubunjwa kwegwebu eliqinile, eminye imikhiqizo yokunamathela.
