99.9% PG Propylene glycol CAS 57-55-6
Propylene glycol (PG C3H8O2) yog ib yam kua tsis muaj xim nrog viscosity ruaj khov thiab nqus dej zoo. Nws yuav luag tsis muaj ntxhiab, tsis yooj yim hlawv thiab yuav luag tsis muaj tshuaj lom. Nws yog sib xyaw nrog dej, ethanol thiab ntau yam organic solvents.
(1) Propylene glycol yog siv ua cov khoom siv raw rau cov resins, plasticizers, surfactants, emulsifiers thiab demulsifiers, nrog rau cov tshuaj antifreeze thiab cov cua sov.
(2) Propylene glycol yog siv los ua roj chromatography ruaj khov kua, solvent, antifreeze, plasticizer thiab dehydrating agent.
(3) Propylene glycol yog qhov nruab nrab ntawm cov tshuaj tua kab mob phenylether methyl cycloazole.
(4) Propylene glycol yog ib qho khoom siv tseem ceeb ntawm cov polyester tsis muaj roj, epoxy resin thiab polyurethane resin.
(5) Propylene glycol feem ntau yog siv rau cov kuab tshuaj rho tawm ntawm ntau yam txuj lom, xim, tshuaj tiv thaiv, vanilla taum, kas fes granule roasted, tsw qab ntuj thiab lwm yam. Ib tug neeg sawv cev moisturizing thiab softening rau khoom qab zib, mov ci, ntim nqaij, cheeses, thiab lwm yam.
(6) Nws kuj tseem siv tau ua tus neeg sawv cev tiv thaiv pwm rau cov noodle thiab cov khoom sau. Ntxiv 0.006% rau cov mis taum pauv, uas tuaj yeem ua rau cov saj tsis hloov pauv thaum cua sov, thiab ua cov pob khoom dawb thiab ci ntsa iab.
(7) Ua ib qho tshuaj nqa, tus neeg sawv cev tshuaj me me. Nws tuaj yeem siv ua tus neeg sawv cev moisturizing, softener thiab solvent hauv cov tshuaj pleev ib ce.
