1. Antioxidant 626 feem ntau yog siv rau hauv kev tsim thiab ua cov yas ntau yam xws li polypropylene, polyethylene, ABS, polycarbonate fiber thiab polyester resin.
2. Antioxidant 626 yog ib qho phosphite auxiliary antioxidant nrog tsawg volatility, uas tuaj yeem tiv thaiv tau polymer discoloration, txo cov polymer degradation rate, thiab txhim kho cov resin lub zog rau cov roj fading. Nws yog tshwj xeeb tshaj yog rau polyolefins thiab olefin copolymers, polycarbonate, polyamide thiab lwm yam engineering plastics, nrog rau roj hmab, coatings thiab adhesives. Ntxiv ntawm antioxidant 626 tuaj yeem txhim kho qhov kev ruaj khov ntawm cov khoom siv, thiab yog dav siv hauv kev ua polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polystyrene, polyvinyl chloride thiab lwm yam thermoplastics thiab elastomers. Tsis tas li ntawd, antioxidant 626 kuj muaj kev tiv thaiv zoo heev ntawm discoloration los ntawm lub teeb thiab cua sov, nrog rau qee qhov teeb pom kev zoo, uas tuaj yeem txhim kho lub teeb, thermal stability, mechanical zog thiab xim stability ntawm cov khoom, yog li ntawd ntev lub neej ntawm cov khoom.
3. Tshuaj antioxidant 626 muaj cov tshuaj lom neeg ruaj khov thiab sib haum zoo nrog feem ntau cov polymers. Nws yog ib qho tshuaj antioxidant phosphite zoo. Nws siv tsis yog tsuas yog txhim kho kev ruaj khov ntawm cov khoom siv xwb, tab sis kuj txhim kho lub teeb, thermal stability, mechanical strength thiab xim stability ntawm cov khoom. Nws yog ib qho tseem ceeb additive siv dav hauv kev lag luam yas.
