POLYESTER POLYOL AIRSON CPU
Tha buannachdan aig na poilealan polyester le cuideam moileciuil de 500-4000G/Mol leithid cromatachd ìosal agus gnìomhachd sheasmhach. Tha buannachdan aig an TPU air a dhèanamh à poilealan polyester leithid slaodachd sheasmhach, gearradh furasta, neart meacanaigeach sàr-mhath, strì an aghaidh caitheamh àrd, strì an aghaidh reubadh agus molltair luath, agus faodar an cuideam moileciuil atharrachadh a rèir riatanasan luchd-ceannach.
Faodar an t-sreath seo de phoilealan polyester a chleachdadh gu farsaing ann an glaodh leaghte teth elastomer TPU, stuth bhròg, pìob, film, còmhdach càball, crios giùlain agus toraidhean polyurethane eile.
