Wopanga mtengo wabwino pentamethldiproproproproplenetine (PMDTTA) Cas: 3855-32-12-12-12-12-12-12-12-12-12-12-12-12-12-12-1.

Kufotokozera kwaifupi:

PMDPTPA ndi chithovu chotsika kwambiri / gel osakaniza, omwe angagwiritsidwe ntchito ku Polytether -type polyurethane chithovu chofewa, polyirethane cholimba cholimba komanso zomatira. PMDPA imagwiritsidwa ntchito makamaka mu chikho chozizira cha HR HR. PMDPTPA imatchedwa Isanu --BASE DI -propleneramine, yomwe ili ndi ntchito zingapo m'makomo ofewa komanso olimba. PMDPA ikhoza kuyankha moyenera ndikuyankha kwa gel gel, ndikuwonjezera chithovu cha chithovu ndi nthawi yoyankhidwa. Chothandizira ichi sichingagwiritsidwe ntchito chokha, komanso kugawana ndi othandizira ena ndi othandizira. PMDPA imatha kusungunuka mu Polyther Polyl.

Imasungunuka mosavuta m'malo ambiri osungunulira. Chithovu ndi ziweto zimachita bwino. Ubwino umagwiritsidwa ntchito ngati chithovu chofewa, chomwe chingapewe kuwonongeka ndi chindapusa cha chithovu, chomwe chili ndi ntchito yabwino kwambiri. Sinthani nthawi yovuta, kulolerana ndikuchiritsa magwiridwe antchito a chithovu cholimba. Sinthani bowo lalikulu la pulasitiki yofewa.

Katundu katundu: Mtunda wowira: 102 ° C / 1mmhg, 1,83 g / cm3, flack ch: 92 Amagwiritsidwa ntchito makamaka kwa ma phenols osasunthika, komanso amagwiritsidwanso ntchito kwa inter -phewarphenols, etc., ndipo nthawi zambiri amagwiritsidwa ntchito ngati othandizirana pakukongoletsa ndi madzi amphongo; utoto wapakatikati
