On April 16, it was reported that the vessel carrying NdBR from Yanshan Petrochemical left Tianjin port for Thailand. This is Yanshan Petrochemical's another breakthrough in SR product export after their first export of BIIR to Venezuela in early March.

Both BIIR and NdBR units of Yanshan Petrochemical are the first industrial production units in China, which were completed and put into operation in 2010 and 2012 respectively. As the most comprehensive SR manufacturer and the earliest green rubber raw material developer in China, Yanshan Petrochemical, based on the existing devices, has continuously carried out quality control, process optimization and technical improvement on BIIR and NdBR. Its products have passed the ISO / TS16949 certification audit of Lloyd's, and it is the first SR product certification enterprise in China. In 2019, the sales volume of NdBR and BIIR of Yanshan Petrochemical reached the highest record since the start of two production units.

Next, Yanshan Petrochemical will focus on the high-end field, promote technical research in the SR field, continuously improve product quality, strengthen the development of new products, enhance differentiated competitive advantage, and effectively enhance the core competitiveness of the enterprise.
