Si-TPV dynamic vulcanizate thermoplastic silicone-based elastomer ua rau EVA ua npuas ncauj thev naus laus zis

piav qhia:

Ethylene vinyl acetate (EVA) yog ib qho copolymer uas ua tau ntau yam los ntawm kev sib xyaw ethylene thiab vinyl acetate monomers. Qhov feem pua ntawm cov vinyl acetate (VA) hauv EVA tuaj yeem sib txawv ntawm 2% txog 60%, uas tso cai rau kev hloov kho nws cov khoom. EVA nrog cov ntsiab lus VA qis dua, kwv yees li 3 wt%, feem ntau siv los hloov kho polyethylene, thaum cov khoom sib xyaw nrog cov ntsiab lus VA siab dua, xws li 5 txog 50 wt%, pom cov ntawv thov hauv kev tsim cov yeeb yaj kiab ntsws, ntim khoom noj, thiab khau, thiab lwm yam.
