Whakamahinga
Ko te Pentaerythritol te mea nui e whakamahia ana i roto i te umanga paninga. Ka taea te whakamahi hei hanga paninga kapia alkyd, ka taea te whakapai ake i te pakeke, te kanapa me te roa o te kiriata paninga. Ka whakamahia hoki hei rauemi mata mō ngā esters rosin e hiahiatia ana mō ngā peita, ngā wanihi me ngā waituhi tā, ā, ka taea te whakamahi hei hanga hinu whakamaroke, paninga mura me ngā hinu whakahinuhinu rererangi. Hei tāpiri, ka whakamahia hoki i roto i te hanga rongoā, patupatu me ētahi atu hua. Kei roto i te ngota pentaerythritol e whā ngā rōpū hydroxymethyl ōrite, ā, he teitei te taumata o te ōritetanga. Nō reira, he maha te whakamahinga hei rauemi mata mō te whakarite i ngā matū polyfunctional. Ka taea e te nitrification o taua mea te whakaputa pentaerythritol tetranitrate, he pahūtanga kaha; ka taea e te esterification te whiwhi pentaerythritol triacrylate, e whakamahia ana hei paninga. Ka taea hoki te whakamahi hei aukati mura mō ngā piri. Ina honoa ki te ammonium polyphosphate, ka taea te whiwhi aukati mura intumescent. Ka whakamahia hoki hei kaihoko hononga mō te polyurethane hei whakarato mekameka peka i roto i te polyurethane.
