Benefiting from factors such as advances in polymerization technology, stable supply of raw material caprolactam, and strong demand in downstream applications, domestic production of nylon 6 chips has grown steadily. The data shows that the output of nylon 6 chips in my country increased from 1.117 million tons in 2010 to 3.21 million tons in 2018. It is expected that with the continuous expansion of application fields, the output of nylon 6 chips in my country will continue to grow steadily.
