Development of high-temperature resistant nylon engineering plastics in China --
[Abstract]:
High temperature resistant nylon is a kind of nylon engineering plastic which can be used at 150 ℃ for a long time. It is a new type of special engineering plastic developed over the past ten years. PA46 is the DSM company announced in 1984 to determine the industrial route, in 1985 to build 150 tons of mid-year pilot equipment, in 1990 to build a kilotons of industrial equipment. PPA46 is formed by condensation of butylamine and adipic acid. Because of its high symmetry, high crystal speed and perfect crystal. The HDT of PA46 can reach 150 ℃ and 285 ℃ after glass fiber enhancement. Dingere industrialization technology is the key technology of PA46, currently only the DSM master.
