99.9% PG Propylene glycol CAS 57-55-6
Propylene glycol (PG C3H8O2) yog cov kua tsis muaj xim nrog cov viscosity ruaj khov thiab nqus dej zoo. Nws yuav luag tsis muaj ntxhiab, tsis yog-flammable thiab yuav luag tsis muaj tshuaj lom. Nws yog tov nrog dej, ethanol thiab ntau yam organic solvents.
(1) Propylene glycol yog siv los ua raw cov ntaub ntawv rau resins, plasticizers, surfactants, emulsifiers thiab demulsifiers, nrog rau cov tshuaj tua kab mob thiab cov khoom siv cua sov.
(2) Propylene glycol yog siv los ua cov roj chromatography nyob ruaj ruaj, kuab tshuaj, tshuaj tiv thaiv kab mob, plasticizer thiab dehydrating agent.
(3) Propylene glycol yog qhov nruab nrab ntawm cov fungicide phenylether methyl cycloazole.
(4) Propylene glycol yog ib qho tseem ceeb raw khoom ntawm unsaturated polyester, epoxy resin thiab polyurethane resin.
(5) Propylene glycol feem ntau yog siv rau kev tshem tawm cov kuab tshuaj ntawm ntau yam txuj lom, pigments, preservatives, vanilla taum, roasted kas fes granule, ntuj tsw thiab lwm yam. Moisturizing thiab softening tus neeg sawv cev rau khoom qab zib, qhob cij, ntim cov nqaij, cheeses, thiab lwm yam.
(6) Nws kuj tseem siv tau los ua tus neeg sawv cev tiv thaiv kab mob rau noodle thiab sau cov tub ntxhais. Ntxiv 0.006% rau cov kua mis, uas tuaj yeem ua rau qhov tsw tsis hloov pauv thaum cua sov, thiab ua kom dawb thiab glossy ntim taum curd.
(7) Raws li tus neeg nqa tshuaj, tus neeg saib xyuas cov tshuaj particle. Nws tuaj yeem siv los ua tus neeg saib xyuas moisturizing, softener thiab hnyav hauv tshuaj pleev ib ce.
