Cim xeeb

DB 886 yog ib qho kev ua haujlwm siab UV stabilization pob tsim

rau polyurethane systems (xws li TPU, CASE, RIM hloov tau yooj yim ua npuas ncauj daim ntawv thov).

DB 866 yog tshwj xeeb tshaj yog muaj txiaj ntsig hauv thermoplastic polyurethane (TPU). DB 866 kuj tseem siv tau rau hauv polyurethane coatings ntawm tarpaulin thiab flooring nrog rau hauv cov tawv hluavtaws.

Daim ntawv thov

DB 886 muab kev ruaj ntseg UV zoo rau cov tshuab polyurethane.

Qhov kev ua tau zoo dua li cov qauv siv UV stabilizer tshwj xeeb tshaj yog hais hauv pob tshab lossis lub teeb xim TPU daim ntaub ntawv.

DB 886 tseem tuaj yeem siv rau hauv lwm cov polymers xws li polyamides thiab lwm yam yas engineering xws li aliphatic polyketone, styrene homo- thiab copolymers, elastomers, TPE, TPV thiab epoxies nrog rau polyolefins thiab lwm yam organic substrates.

Nta / txiaj ntsig

DB 886 muaj kev ua tau zoo dua thiab ua kom muaj txiaj ntsig ntau ntxiv

tshaj cov pa hluav taws xob stabilization systems:

Thawj xim zoo heev

Superior xim tuav thaum raug UV

Txhim kho lub sij hawm ntev-thermal-stability

Ib leeg-additive tov

Yooj yim dosable

Cov khoom siv dawb rau me ntsis daj, dawb-ntws hmoov

Cov lus qhia rau kev siv

Siv qib rau DB 886 feem ntau yog nyob nruab nrab ntawm 0.1% thiab 2.0%

nyob ntawm substrate thiab ua tej yam kev mob. DB 866 tuaj yeem siv ib leeg lossis ua ke nrog lwm cov khoom siv ntxiv xws li antioxidants (hindered phenols, phosphites) thiab HALS lub teeb stabilizers, uas feem ntau pom muaj kev sib koom ua ke. Cov ntaub ntawv kev ua tau zoo ntawm DB 886 muaj rau ntau yam kev siv
