Kev cia khoom
Qhov no PTMEG TDI Polyurethane Prepolymer yuav tsum muab cia rau hauv qhov chaw txias, qhuav, tsis txhob ya raws thiab kub. Lub txee lub neej ntawm unopened prepolymer yog kaum ob lub hlis.
Daim ntawv thov
PTMG TDI Polyurethane Prepolymer muaj ntau yam kev siv:
1. Elastomers: PTMEG-raws li prepolymers yog dav siv los tsim cov ntaub ntawv elastomeric, uas paub txog lawv qhov yooj, durability, thiab tsis kam mus rau puas. Cov elastomers no tuaj yeem siv rau hauv cov khoom siv tsheb, cov ntsaws ruaj ruaj, gaskets, thiab cov khoom ua si.
2. Txheej: PTMEG polyurethane prepolymers yog ua hauj lwm hauv cov txheej txheem tiv thaiv thiab kho kom zoo nkauj. Lawv muab cov adhesion zoo heev, tshuaj tiv thaiv, thiab huab cua, ua rau lawv tsim nyog siv rau hauv kev lag luam, tsheb, thiab vaj tse txheej txheej.
3. Adhesives: Vim lawv cov khoom muaj zog sib txuas thiab yoog raws, PTMEG prepolymers yog siv rau hauv cov nplaum rau ntau yam substrates, suav nrog hlau, yas, thiab textiles. Lawv muaj txiaj ntsig tshwj xeeb hauv cov ntawv thov uas xav tau kev sib txuas ua haujlwm siab.
4. Ua Npuas Ncauj: PTMEG Prepolymer Polyurethaneare siv los tsim cov foams hloov tau yooj yim thiab nruj. Cov foams no feem ntau pom muaj nyob hauv cov rooj tog zaum, txaj txaj, rooj zaum hauv tsheb, thiab cov ntaub ntawv rwb thaiv tsev.
5. Textiles : Hauv kev lag luam textile, PTMEG prepolymers yog siv los txhim kho cov khoom ntawm cov ntaub, muab cov dej tsis kam, elasticity, thiab txhim kho durability.
6. Cov Khoom Siv Kho Mob: PTMEG polyurethanes tau siv ntau dua hauv kev kho mob rau cov ntawv thov xws li catheters, implants, thiab cov ntaub qhwv lub qhov txhab vim lawv cov biocompatibility thiab yooj.
7. Sealants: PTMEG lub casting Polyurethane prepolymer kuj yog siv nyob rau hauv sealant formulations, muab zoo heev adhesion thiab yooj rau kev tsim kho thiab kev siv tsheb.
