ABSTRACT 1,2‐Epoxidized polybutadiene (1,2‐epoxidized PB) has been used as an additive in poly(vinylidene fluoride‐co‐hexafluoropropylene) (fluoroelastomer [FKM]) formulations. As global awareness surrounding Sustainable Development Goals (SDGs) continues to rise, the demand for safer, eco‐friendly materials is increasing, our rubber material aligns with the SDGs, specifically Goal 3 (Department of Economic and Social Affairs) and Goal 12 (Responsible Consumption and Production). Lead monoxide (PbO) has traditionally been used as an acid acceptor in halogenated rubbers. However, PbO is prohibited by various regulations due to its toxicity, and currently no candidate offering a good balance between acid acceptance and rubber properties. We have researched liquid 1,2‐epoxidized PB, and our study shows it acts as a sustainable alternative as an acid acceptor in halogenated rubber formulations, replacing PbO. This innovative solution is a nonhazardous material formulation that complies with regulations set by REACH and RoHS.
