Kev siv cov khoom siv PCTG hauv kev ntim khoom kom zoo nkauj

PCTG yog cov yas pob tshab thiab amorphous copolyester. Cov comonomer nquag siv hauv PCTG yog 1, 4-cyclohexanedimethanol (CHDM), uas yog hu ua polyethylene terephthalate-1 , 4-cyclohexanedimethanol ester. Nws yog polycondensation khoom ntawm peb monomers ntawm terephthalic acid (PTA), ethylene glycol (EG) thiab 1, 4-cyclohexanedimethanol (CHDM) los ntawm transesterification. Piv nrog PET, nws muaj ntau dua 1, 4 -Cyclohexanedimethanol comonomer muaj ntau ethylene glycol comonomer dua li PCT, yog li qhov kev ua tau zoo ntawm PCTG yog qhov txawv ntawm PET thiab PCT. PCTG yog amorphous copolyester. Nrog rau qhov nce ntawm CHDM nyob rau hauv lub copolymer, lub melting point txo, lub iav hloov kub nce, thiab crystallinity txo, thiab thaum kawg ib amorphous polymer yog tsim. Feem ntau, cov ntsiab lus ntawm CHDM hauv PCTG yog qhov tsim nyog ntawm 30 feem pua ​​-40 feem pua.

Nws muaj qhov zoo viscosity, clarity, xim, tshuaj lom neeg tsis kam, thiab kev ntxhov siab ua kom dawb huv. Yuav ua tau sai sai thermoformed los yog extrusion tshuab molded. Viscosity zoo dua li acrylic (acrylic). PCTG yog amorphous copolyester. Nws cov khoom yog pob tshab heev thiab muaj kev cuam tshuam zoo heev. Nws yog tshwj xeeb tshaj yog tsim rau kev tsim cov khoom tuab-walled pob tshab. Nws cov txheej txheem thiab kev tsim cov khoom tuaj yeem tsim los ntawm txhua tus qauv raws li tus tsim qauv lub hom phiaj. Cov txheej txheem Moulding ib txwm muaj xws li extrusion, txhaj tshuaj molding, tshuab moulding, thiab blister molding tuaj yeem siv dav hauv kev lag luam ntawm cov ntaub ntawv, kev ua haujlwm siab shrink films, fwj thiab cov ntaub ntawv profiled, thiabntim tshuaj pleev ib ce.Thiab tib lub sijhawm, nws cov kev ua haujlwm theem nrab yog qhov zoo heev, thiab cov pa Machining tiav.

PCTG muaj cov iav zoo li pob tshab thiab qhov ntom ntom ze rau iav, zoo gloss, tshuaj tiv thaiv corrosion, cuam tshuam tsis kam, thiab ua tau yooj yim, thiab tuaj yeem txhaj tshuaj molded, txhaj tshuaj stretch tshuab molded thiab extrusion tshuab molded. Nws tseem muaj peev xwm tsim cov duab tshwj xeeb, zoo li thiab tshwj xeeb cov teebmeem xws li cov xim vibrant, frosted, marbled, metallic thiab lwm yam. Nws tseem tuaj yeem siv lwm cov polyesters, elastomeric plastics lossis ABS rau kev txhaj tshuaj ntau dhau.

Cov khoom lag luam suav nrog cov fwj tshuaj tsw qab thiab lub kaus mom, lub raj mis kom zoo nkauj thiab lub kaus mom, lipstick raj, cov khoom siv tshuaj pleev ib ce, deodorant ntim, talcum hmoov fwj thiab eyeliner teeb, thiab lwm yam. PETG txhaj tshuaj molding cov khoom muaj xws li cov khoom siv kho mob xws li lim, Eustachian raj, raj txuas, twj, clips. , thiab cov cuab yeej lim ntshav. Cov khoom siv hauv tsev xws li khob, tais diav, ntsev shakers, kua txob shakers, thiab lwm yam, muaj cov pob tshab zoo, gloss, zoo toughness, processability thiab zoo heev xim.

PCTG yog cov khoom siv pob tshab copolyester. Nws muaj lub siab transparency, zoo toughness thiab cuam tshuam lub zog, zoo heev tsis tshua muaj kub toughness, siab kua muag kuj thiab zoo ua hauj lwm, zoo heev tshuaj lom neeg kuj. Nws tuaj yeem ua tiav los ntawm ib txwm extrusion, txhaj tshuaj molding, tshuab moulding thiab blister molding txoj kev. Siv dav hauv daim ntawv, kev ua haujlwm siab shrink zaj duab xis, lub raj mis thiab profile lag luam; tuaj yeem siv los tsim cov khoom ua si, khoom siv hauv tsev thiab khoom siv kho mob, thiab lwm yam.; dhau US FDA cov qauv kev sib cuag zaub mov, tuaj yeem siv rau hauv cov zaub mov, tshuaj, ntim tshuaj pleev ib ce thiab lwm yam.
