Polyester POLYOL BAKENG SA CPU
Letoto la li-polyester polyols li sebelisoa haholo ho li-elastomers, 'me ho latela litlhoko tsa bareki ho lokisa boima ba limolek'hule.Lihlahisoa tse tlase tse hlahisoang ke letoto lena la li-polyols li na le litšobotsi tsa ho hanyetsa ho roala, ho hanyetsa ho phutha, ho hanyetsa ho qhaqha le matla a phahameng a mochine.
Letoto la li-polyester polyols li sebelisoa haholo lefapheng la ho lahlela li-elastomers tsa polyurethane, tse sebelisoang haholo ka poleiti ea sieve e thata ea polyurethane, li-caster, libethe, lipoleiti le mekoallo, lihlahisoa tsa potting tse bōpiloeng.
