Unsaturated resin refers to a polymer compound containing unsaturated double bonds produced by the polycondensation reaction of dibasic acid and diol, epoxy resin refers to a type of polymer containing more than two epoxy groups in the molecule Collectively. It is a polycondensation product of epichlorohydrin and bisphenol A or polyol. What are the differences between them?
1. The characteristics are different: epoxy resin is characterized by high compression and tensile strength, long-term exposure to high temperature conditions can still maintain good mechanical properties, arc resistance, UV aging resistance and weather resistance it is good. Unsaturated resins are characterized by light weight, high strength, good corrosion resistance, excellent electrical properties, unique thermal properties, excellent processing technology performance, and good material designability.
2. Different uses: epoxy resin is mainly used in coating industry and electronics industry. Epoxy for composite molding (mainly used in printed circuit boards in the electronics industry) accounts for a quarter. Unsaturated resins are mainly used in the field of construction, FRP pipes, tanks, tanks and other anti-corrosion products and projects, FRP vehicles, FRP boats, FRP amusement equipment, FRP transportation equipment, labor insurance and security supplies.
3. Different composition modes: Epoxy resin refers to the general term for a class of polymers containing more than two epoxy groups in the molecule. It is a polycondensation product of epichlorohydrin and bisphenol A or polyol. Unsaturated resin refers to a polymer compound containing an unsaturated double bond produced by a polycondensation reaction of a dibasic acid and a diol.
