POLYESTER POLYOL YECPU
Iyo polyester polyols ine molecular huremu hwe500-4000G/Mol ine zvakanakira yakaderera chromaticity uye yakagadzikana chiitiko.Iyo TPU yakagadzirwa kubva kupolyester polyols ine mabhenefiti eyakagadzika viscosity, kucheka nyore, yakanakisa mechaniki simba, yakakwirira kupfeka kuramba, kuramba kubvarura uye nekukurumidza kuumba, uye inogona kugadzirisa molecular huremu zvinoenderana nezvinodiwa nevatengi.
Iyi nhevedzano yepolyester polyols inogona kushandiswa zvakanyanya muTPU elastomer inopisa inonyungudika adhesive, shangu zvinhu, pombi, firimu, tambo sheath, conveyor bhandi uye zvimwe zvigadzirwa zve polyurethane.
