Polyester POLYOL AIRSON CPU
Tha na buannachdan aig na polyols polyester le cuideam moileciuil de 500-4000G / Mol bho chromaticity ìosal agus gnìomhachd seasmhach.Tha na buannachdan aig an TPU a tha air a dhèanamh le polyols polyester airson slaodachd seasmhach, gearradh furasta, neart meacanaigeach sàr-mhath, neart caitheamh àrd, strì an aghaidh deòir agus cumadh luath, agus faodaidh e cuideam moileciuil atharrachadh a rèir riatanasan teachdaiche.
Faodar an t-sreath seo de polyols polyester a chleachdadh gu farsaing ann an adhesive leaghadh teth elastomer TPU, stuth bhròg, pìob, film, còmhdach càball, crios giùlain agus toraidhean polyurethane eile.
