Cia
Rau PTMEG TDI Polyurethane Prepolymer Rau Log, cuam tshuam ntawm prepolymer cua sov Lub isocyanate (NCO) cov ntsiab lus ntawm prepolymer yuav txo qis lub sijhawm, tshwj xeeb tshaj yog nyob rau hauv cov cua sov. Cov hauv qab no yog lub sijhawm ntawm cov kev hloov me me hauv prepolymer nyob rau hauv qee qhov kub thiab txias.
