Pb raj yog hom polymer inert polymer, uas tau yug hauv xyoo 1970s. Nws yog dav siv nyob rau hauv lub neej tam sim no thiab lub neej, thiab cov nram qab no cov kws lag luam piav qhia txog cov txuj ci tseem ceeb.
Pb resin yog synthesized los ntawm butene 1 polymer synthesis, nws muaj kub kub, durability, tshuaj stability thiab plasticity, tasteless, non-toxic, ntxhiab, kub qhov - 30 ℃ 100 ℃, nrog txias resistant, kub resistant, siab voltage , tsis xeb, corrosion, fouling, lub neej ua haujlwm ntev (txog 50-100 xyoo), thiab cov laus ua haujlwm tsis zoo, muaj peev xwm tau ntev ntev yog ib qho ntawm cov ntaub ntawv tshuaj lom neeg tshaj plaws hauv lub ntiaj teb. Nws yog dav siv nyob rau hauv ntau lub teb chaws nyob hauv lub ntiaj teb. Muaj ib lub koob npe nrov rau "kub hauv yas".
