Kev piav qhia txog tus cwj pwm:

DB 117 yog ib qho khoom siv uas pheej yig, ua kua kub thiab lub teeb stabilizer, muaj cov khoom siv stabilizer thiab cov khoom antioxidant, muab kev ruaj khov zoo rau ntau lub polyurethane systems thaum nws siv.

Cov Khoom Siv Lub Cev

Tsos: Daj, kua nplaum
Qhov Ceev (20 °C): 1.0438 g/cm3
Qhov khov (20 ° C): 35.35 mm2 / s

Cov ntawv thov

DB 117 yog siv rau hauv polyurethanes xws li Reaction Injection Molding, thermoplastic polyurethane synthetic tawv, cast polyurethanes, thiab lwm yam. Cov sib xyaw kuj tseem siv tau rau hauv sealant thiab nplaum daim ntawv thov, hauv polyurethane txheej ntawm tarpaulin thiab pem teb, hauv molded foams nrog rau hauv cov tawv nqaij sib xyaw.

Cov yam ntxwv/cov txiaj ntsig

DB 117 tiv thaiv kev ua tiav, lub teeb thiab huab cua ua rau muaj kev puas tsuaj ntawm cov khoom polyurethane xws li cov khau hauv qab, cov twj paj nruag thiab cov vaj huam sib luag qhov rooj, lub kauj tsheb, lub qhov rais encapsulations, lub taub hau thiab caj npab so hauv txoj hauv kev pheej yig.
DB 117 tuaj yeem ntxiv tau yooj yim rau cov tshuab aromatic lossis aliphatic polyurethane rau cov thermoplastic moldings, semi-rigid integral foams, in-mold skinning, dope applications. Nws tuaj yeem siv nrog cov ntaub ntawv ntuj thiab pigmented. Tshwj xeeb tshaj yog tsim rau kev npaj cov xim sib zog rau cov kab ke saum toj no.
DB 117 yog ib qho yooj yim rau twj, kua dej uas nchuav tau uas ua rau tsis muaj plua plav, tsis siv neeg noj tshuaj thiab luv lub sijhawm sib tov. Nws tso cai rau kom tau txais kev tsim khoom hauv kev txo qhov hnyav lossis ntsuas rau ib qho kev ua haujlwm. Ua ib pob kua tag nrho tsis muaj kev tso dej ntawm cov khoom ntxiv hauv theem polyol tshwm sim txawm tias thaum kub qis.
Tsis tas li ntawd xwb, DB 117 tau ua pov thawj tias nws tiv taus kev tawm tawm / crystallization hauv ntau lub tshuab PUR uas tau sim.

Kev Siv:

0.2% thiab 5%, nyob ntawm seb lub substrate thiab kev ua tau zoo ntawm daim ntawv thov zaum kawg.
