He papanga paninga tuarua mo te taura whatu (PBT)
Whakaahuatanga Poto:
Ko nga rauemi PBT mo te ngongo ngongo muka whatu ko te ahua o nga rauemi PBT mahi nui i whiwhi mai i nga matūriki PBT noa i muri i te roha o nga mekameka me te tackification. He pai rawa atu nga ahuatanga o te aukati tensile, te whakapiko i te aukati, te aukati paanga, te whakaheke iti, te aukati hydrolysis, me etahi atu, he pai te mahi tukatuka me te pai o te hototahi ki te masterbatch tae noa o te PBT. Ka whakamahia ki te taura moroiti, te taura whitiki me etahi atu taura whakawhitiwhiti.
Paerewa: ROSH
Tauira: JD-3019
Taupānga: Ka whakamahia ki te whakaputa ngongo ngongo muka whatu
