On March 21st, an investor asked Wanrun Group (002643), "Could you please provide an update on the progress of the first phase of Penglai New Materials? What is the planned production capacity for thermoplastic polyimide? If the product demand exceeds supply and expansion is needed, would you utilize a flexible production line directly, or would a new production line need to be built?"
