Epoxy-functionalized polymer chain extenders pass identification
China Shanxi Institute of Chemical drying Reuters done KL-E series epoxy functional polymer chain extender development projects, scientific and technological achievements through the identification of a few days ago Science and Technology Department of Shanxi Province. KL-E series epoxy functionalized polymer chain extenders include KL-E4300, 4370 and 4370B, which are made of vinyl monomers such as glycidyl methacrylate and styrene and lower alcohol esters of acrylic acid. Polymerization and suspension polymerization process copolymerization synthesis, widely used in polylactic acid and other polyester biodegradable plastics and polybutylene terephthalate and other condensed engineering plastic chain expansion modification, can improve the resin melt strength, processing Stability and mechanical properties. Pup joint is an element cementing and fracturing equipment delivery high-pressure fluid. Widely used in the acidic operating ermvironment. in the high-pressure discharge line, input line, a temporary flow lines,well testing, and other high-voltage transmission line on the line, Overall pipeline specifications are 2in-3 in, length 05 m,1 m,1.5 m,2m,2.5m,3m,3.5m and so on, rated working pressure of 42MPa 105MPa, working temperature-29 ℃ 121 ℃.We can Produce reduction according to customer requirement.Pup joint is an element cementing and fracturinq equipment delivery high-pressure fluid.
