Bis (2,2,6,6-tetramethyl-4-piperidyl) sebacate CAS 52829-07-9
Lub teeb stabilizer 770 yog cov hmoov dawb los yog daj me ntsis crystalline hmoov, uas yog ib yam khoom uas tsis tshua muaj molecular hnyav ntawm ntau yam hindered amine teeb stabilizers. Nws yog soluble hauv cov kuab tshuaj organic xws li ethanol, ethyl acetate, benzene, thiab insoluble hauv dej. Nws yog tus sawv cev ntau yam ntawm qhov hnyav molecular HALS. Nws muaj cov photostability siab thiab haum rau cov khoom xws li polyethylene, polypropylene, polystyrene, ABS, thiab lwm yam. Nws cov nyhuv photostability yog 3-4 npaug ntawm ultraviolet absorbers thiab npib tsib xee quenchers, tshwj xeeb tshaj yog nyob rau hauv cov khoom polyolefin. Vim nws qhov me me ntawm cov txheeb ze molecular hnyav, siab volatility, tsis muaj zog tiv thaiv kev txav thiab rho tawm, nws yog tsim rau siv hauv cov khoom tuab.

Bis (2,2,6,6-tetramethyl-4-piperidyl) sebacate yog tsim rau polypropylene, high-density polyethylene, polyurethane, polystyrene, ABS resin, thiab lwm yam. Nws 770 lub teeb stabilization nyhuv yog superior rau feem ntau siv lub teeb stabilizers. Thaum siv ua ke nrog cov tshuaj antioxidants, nws tuaj yeem txhim kho cov cua sov, thiab thaum siv ua ke nrog UV absorbers, nws kuj muaj cov nyhuv synergistic, ntxiv dag zog rau cov nyhuv photostability. Bis (2,2,6,6-tetramethyl-4-piperidyl) sebacate yog siv rau polypropylene, high-density polyethylene unsaturated resin, polyurethane, polystyrene, thiab ABS resin, thiab nws cov nyhuv photostability yog superior rau feem ntau siv lub teeb stabilizers.
Feem ntau ntim rau hauv 25kg / nruas, thiab kuj tuaj yeem ua pob customized.
