I-Antioxidant 168 cas 31570-04-4 Tris (2,4-di-tert-butylphenyl) phosphite

I-Antioxidant 168 yi-phosphite antioxidant egqwesileyo. Ingumgubo omhlophe ngembonakalo. Inyibilika ngokulula kwizinyibilikisi ze-organic ezifana ne-benzene, i-chloroform kunye ne-cyclohexane. Inyibilika kancinane kwi-ethanol, iacetone, kwaye ayinyibiliki emanzini nakwi-alcohol Solvent, inyibilika kancinane kwii-esters. Ubuthi obuphantsi, ukuguquguquka okuphantsi, ukuzinza okuphezulu kwe-thermal, ukuxhathisa okugqwesileyo kwe-hydrolysis, kwaye kunokubola ngokufanelekileyo i-hydroperoxides eveliswa ngexesha lokwenziwa kwe-thermal ye-polymeric materials.Kukho ngaphezu kweshumi elinesibini imiqulu edityaniswe ne-phenolic antioxidants, esetyenziswa ngokubanzi kwi-polyolefins (efana ne-aspolyethylene kunye i-polypropylene) kunye ne-olefin copolymers, i-polyamides, i-polycarbonates, i-PS resins, i-PVC, iiplastiki zobunjineli, kunye nerabha kunye neemveliso zepetroleum, izinto zepolymer ezifana ne-ABS resin.
