Epoxidized Polybutadiene (EPB)

EPB ndi gulu la epoxy lomwe limalowetsedwa mu unyolo wa PB, womwe uli ndi ubwino wokana mafuta, kukana ukalamba, kuwonekera bwino, kugwira ntchito bwino kutentha pang'ono, ndi zina zotero. Gulu la epoxy mu unyolo wa mamolekyu ndi gulu lochitapo kanthu, lomwe lingachiritsidwe ndi mitundu yosiyanasiyana ya isocyanates ndi epoxy curing agents.

Polima wochiritsidwayo ali ndi makhalidwe abwino akuthupi ndi a mankhwala, mphamvu yabwino kwambiri yolumikizirana ndi chitsulo ndi galasi ndi zinthu zina zosakhala zachitsulo, mphamvu yabwino ya dielectric, kuchepa kochepa kwa shrinkage, kuuma kwambiri, kukhazikika ku alkali ndi voliyumu yambiri, zomwe zingathandize kwambiri mphamvu ya makina, mphamvu yolumikizirana ndi kukana kutentha kwa zinthu za polyurethane.

Magulu a polar amawongolera mphamvu zomangira za chinthucho ndi zitsulo ndi zinthu zosakhala zachitsulo; Zingagwiritsidwe ntchito mu zomatira, zomatira, zokutira, zomatira za epoxy resin, polyurethane elastomers, ndi zina zotero.
