According to a report from CSC, the signing ceremony for the procurement of equipment for the wet diaphragm production line of Hengli Petrochemical (600346) was held in Hengli (Suzhou) Industrial Park on December 26th.

According to the agreement, Kanghui New Materials, a subsidiary of Hengli Petrochemical, will introduce 12 wet lithium battery diaphragm production lines from Japan's Zipu Machinery Co., Ltd. and Qingdao China Science and Technology Hualian New Materials Co., Ltd., with an annual production capacity of 1.6 billion square meters. The move marks Hengli Petrochemical's entry into the field of lithium diaphragm and the increase in the market of chemical new energy materials.

Market data show that Hengli Petrochemical's main business includes the production, R & D and sales of PX, acetic acid, PTA, ethylene glycol, polyester chips, civil polyester filaments, industrial polyester filaments, polyester films, engineering plastics and PBS/PBAT biodegradable new materials involved in the whole industrial chain of refining, petrochemical and polyester materials.

Hengli petrochemical civil filament production capacity ranks among the top five in the country, and industrial filament production capacity ranks third in the country. It is one of the largest and most technologically advanced manufacturers of polyester civil filament and industrial filament in China.

Hengli Sinopec's entry into the lithium battery diaphragm market has taken a fancy to the great potential of the market: lithium diaphragm is one of the most technical high value-added materials in lithium battery materials, with a gross profit margin of more than 70%.

According to statistics, shipments of lithium diaphragms in China increased by 202% in the first half of 2021 compared with the same period last year. It is estimated that the global demand for lithium diaphragm is expected to increase from 6.34 billion square meters to 19.58 billion square meters from 2020 to 2023, with an average annual growth rate of 45.6 percent.
