Polyester POLYOL YECPU
Iwo akateedzana polyester polyols anonyanya kushandiswa mu elastomers, uye zvinoenderana nezvinodiwa nevatengi kugadzirisa huremu hwemamorekuru.Zvigadzirwa zvepasi zvinogadzirwa neiyi nhevedzano ye polyols zvine hunhu hwekupfeka kuramba, kupeta kuramba, kubvarura kuramba uye yakakwirira mechanical simba.
Iwo akatevedzana epolyester polyols anoshandiswa zvakanyanya mumunda wekukanda polyurethane elastomers, anonyanya kushandiswa mukuomarara polyurethane sieve ndiro, macaster, machira, mahwendefa nemabhawa, akaumbwa zvigadzirwa zvehari.
