Silicone High Temp Flexible Roof rau Yeeb Nkab Hlau Roofing Yeeb Nkab Flashing

EPDM yog M-Class roj hmab raws li ASTM tus qauv D-1418; M chav kawm suav nrog elastomers uas muaj cov saw hlau saturated ntawm hom polyethylene (tus M muab los ntawm cov lus tseeb dua polymethylene). EPDM yog tsim los ntawm ethylene, propylene, thiab diene comonomer uas ua rau crosslinking ntawm sulfur vulcanization. Tus txheeb ze yav dhau los ntawm EPDM yog EPR, ethylene propylene roj hmab (tseem siv tau rau cov hluav taws xob hluav taws xob hluav taws xob), uas tsis yog los ntawm cov khoom siv hluav taws xob diene thiab tuaj yeem tsuas yog crosslinked siv radical txoj kev xws li peroxides.
