Polyester Polyol Bakeng sa CPU
Li-polyester li sebelisoa haholo ho li-elastomers tse sebelisoang haholo ho esele, le ho latela litlhoko tsa bareki ho fetola boima ba limok'hule. Lihlahisoa tse theotsoeng ke letoto lena la mabenkele li na le litšobotsi tsa ho hanyetsa, ho ripiha khanyetsong le matla a phahameng le matla a phahameng.
Letoto la polyester makoli a polyester a sebelisoa hohle tšimong ea polyurong Olalathane, haholo-holo ka thata ea Polyureune.
