PVA 2699 thiab PVA 2488: Kev txawv thiab cov txiaj ntsig.

PVA 2699 yog qhov paub zoo tias yog ib qho khoom soluble hauv dej uas muaj peev xwm instant miscibility hauv lwm cov khoom dej. Cov yam ntxwv zoo li no nce qhov kev ua haujlwm thiab yog li ntawd nws pab kom cov khoom uas tau npaj tau raws li cov requirments ntawm ntau qhov applications.

Vim PVA 2699 muaj qhov hnyav molecular siab, nws qhia tau qhov muaj zog thiab kev ruaj khov uas tseem ceeb rau cov ntawv thov uas xav tau zog. Qhov no ua kom paub tseeb tias cov khoom lag luam kawg yog resistant rau kev nyuaj siab uas tom qab ntawd ua kom muaj durability rau cov neeg siv kawg.

PVA 2699 yog siv tau rau ntau txoj haujlwm thiab rau ntau hom khoom, suav nrog textiles thiab adhesives. Nws qhov flexibility pab cov tuam txhab kom muaj peev xwm sib sau lawv cov khoom kab thiab kev lag luam ntawm qhov loj los ntawm kev siv ib qho polymer rau ntau qhov chaw uas txhim kho kev ua haujlwm.
