4,4-diaminodicyclohylmethane (PACM)
1. Kev Kawm Txuj Ci & Kev Ntsuas Cov Lus
Purity: ntau dua los yog sib npaug rau 99.0%
Siab siab ua kom tiav tsawg kawg ntawm cov immurities nyob rau hauv txoj kev tiv thaiv hauv qab, txo cov khoom sab hauv polyureaa txheej kho.
2. Cov ntsiab lus tseem ceeb
Rau polyurea high - kub txheej kub:
Tshwj xeeb qhov kev ua kom ntev (TGA qhia txog 5% poob ntawm 320 degree) - Outperforms aromatic uas koom nrog 80 degree. Qhov txuas ntxiv txheej txheej liftespan hauv kev lag luam ncu lossis cov cav cav.
Tus lej xim qis (APHA tsawg dua los yog sib npaug rau 30) -ments.
Tus lej xim qis (APHA tsawg dua los yog sib npaug ntawm 30) - tswj cov txheej pob tshab, zoo tagnrho rau kev kho kom zoo nkauj siab- qhov chaw sov.
Rau pob tshab nylon:
Amine Cov Nqi Ruaj Ntseg ua kom nruj polymerization kinetics, txo batch}- batch viscosity viscosity hauv nylon melts.
Cycloaliphatic structure minimizes light absorption, resulting in nylon with >85% lub teeb kev hloov pauv
Rau epoxy catch cov neeg sawv cev:
Long Lauj Lauj (6 {{- 8℃nrog cov qauv epoxy) - txhim kho kev ua haujlwm rau cov txheej txheem loj-cov txheej txheem loj.
Kev sib cav siab siab tshaj tawm {{0} kev kho (iav transiting (iav transition (sib npaug nrog 120 degree) - txhim kho tshuaj lom neeg tawm tsam cov kuab tshuaj thiab cov kua qaub.
