Polyester Polyl ya CPU
Zoterezi polyester ma polylols zimagwiritsidwa ntchito makamaka m'ma elastomers, komanso malinga ndi zomwe makasitomala amafuna kuti musinthe thupi. Zinthu zotsika zopangidwa ndi mibadwo ya polylols ili ndi mawonekedwe a kuvala kukana, kupukutira kukana, kung'amba ndi mphamvu yayikulu.
Mitundu ya polyester polyls imagwiritsidwa ntchito kwambiri poponyera ma polyirestomer, makamaka ogwiritsira ntchito mbale zapamwamba za polyurethethane, zojambula, mbale ndi miyala, zopangira mafuta.
