Polyester Polyol airson CPU
Tha polyols Polyester Polyeos sa mhòr-chuid air an cleachdadh sa mhòr-chuid ann an elastomers, agus a rèir riatanasan luchd-cleachdaidh gus an cuideam moilecular atharrachadh. Tha feartan an aghaidh, an aghaidh pasgaichte, pasgadh agus neart meacanaigeach àrd.
Tha an t-sreath de pholyocan Polyester air a chleachdadh gu farsaing anns an raon a thathar a 'tilgeadh elastomers polythetthae plàta Sieve Polyrothene, casters, truinnsearan agus bàraichean, toraidhean poting le molld.
