When PA66 nylon 66 salt is prepared from diacid and two meta amine, it is necessary to strictly control the molar ratio as the molar ratio, so as to get a polymer with high molecular weight. Therefore, the mixture of adipic acid and adipamine must be mixed into nylon 66 salt in production. The preparation of nylon 66 salt is to mix adipic diamine solution and adipic acid solution at the temperature above 60 centigrade, neutralize it and precipitate after salt formation. After filtration, alcohol washing and drying, after ***, about 63% of the water solution is prepared for condensation.PBT 3501TPU/B60AESDMPC/ABSUltra4140PGPPˉJHC-371PPˉAX764PC DEP32XXCPP/17T1022EVA400A-CPCˉIN2200 PA66马来西亚巴斯夫A3HG7 BKEVA EB591PPˉHJ730PCˉ123HSRPC/ABS CY5220PC/K-20UV28EVA1807GPA6/B30S【
