On November 7th, at the 2020 China Advanced Polymer Composites Forum held in Changsha today, ZZSD New Materials Group and CRRC jointly demonstrated their research work in recent years to solve key technical problems in basic materials.
"Key basic materials are controlled by others, they are expensive and costly, and risk uncertainty increases." ZZSD Chairman Yang Jun introduced that with the rapid development of China's rail transit field, there is a demand for aramid materials for traction transformers and traction motors. It is also getting bigger and bigger. China's rail transit high-end aramid materials previously relied entirely on imports, and there was a supply outage, which caused the stagnation of the manufacturing of traction motors and transformers, which seriously restricted the development of China's rail transit train industry.
This time, ZZSD, together with CRRC, will make use of its expertise in high-performance material technology and application fields, and jointly build a "high-performance material development platform" to promote the domestic production of high-performance aramid materials used in major areas such as rail transit and aerospace in China.化. At present, the main performance of the aramid insulation paper products developed by ZZSD has been comparable to that of imported high-end products, and has been evaluated and verified by downstream users such as CRRC Zhuzhou Electric and Yongji Electric.
At present, ZZSD has a full range of aramid board production capacity.
