POLYESTER POLYOL KWA CPU
Polyols za polyester na uzito wa Masi ya 500-4000G/Mol zina faida za chromaticity ya chini na shughuli imara.TPU iliyotengenezwa na polyols ya polyester ina faida za mnato thabiti, kukata kwa urahisi, nguvu bora za mitambo, upinzani wa juu wa kuvaa, upinzani wa machozi na ukingo wa haraka, na inaweza kurekebisha uzito wa Masi kulingana na mahitaji ya wateja.
Mfululizo huu wa polyols polyester inaweza kutumika sana katika TPU elastomer moto melt adhesive, nyenzo kiatu, bomba, filamu, cable ala, conveyor ukanda na bidhaa nyingine polyurethane.
