Epoxy chlorohydrin copolymer rubber is a type of synthetic rubber material obtained through the copolymerization of epichlorohydrin (epoxy chloride) with other monomers such as ethylene oxide, allyl glycidyl ether, and so forth. Characterized by its unique molecular structure, this rubber exhibits excellent physical and chemical properties, including oil resistance, cold resistance, ozone resistance, weatherability, and flame retardancy. The ratio of different monomers used in the copolymerization process can be adjusted to tailor the properties of the final rubber product for various applications.
Specifically, homopolymers of epoxy chlorohydrin form saturated aliphatic polyether elastomers with chloromethyl side chains. When copolymerized with ethylene oxide, an ECH/EO binary copolymer is generated. Further incorporation of additional comonomers like allyl glycidyl ether leads to ECH/EO/AG ternary copolymers, which not only retain excellent chemical resistance but may also exhibit enhanced processing characteristics and specific reactive functionalities.
These rubber products find widespread application across various industries, including aerospace-grade film products, dry films and solder masks for printed circuit boards, high-performance adhesive tapes, seals for fuel tanks and transformers, cable sheathing, and other applications requiring high levels of weatherability and sealing performance.
