万华化学，三大产品扩能

Core Viewpoint - Wanhua Chemical is expanding its production capacity in three key projects, focusing on specialty isocyanates, which enhances its position in the industry and completes its product chain [2][4]. Group 1: IPDA Expansion - The IPDA expansion project aims to increase the capacity from 50,000 tons/year to 100,000 tons/year, alongside the IPN facility from 55,000 tons/year to 100,000 tons/year [3]. - This expansion is a significant move in the specialty isocyanate sector, complementing the recent acquisition of Vencorex's specialty isocyanate business, which adds 20,000 tons/year of IPDI capacity [4]. - IPDA is a crucial organic synthesis intermediate used to produce IPDI, which is widely applied in high-end polyurethane materials [5]. Group 2: PDMS Expansion - The PDMS expansion project will increase the capacity from 9,000 tons/year to 29,000 tons/year by adding two new production lines and adjusting existing ones [9]. - PDMS is a key raw material for high-end polycarbonate production, particularly in silicone copolymer PC, which has applications in high-tech fields such as 5G communications and medical devices [10]. Group 3: P Alcohol Expansion - The P alcohol project involves upgrading the existing facility to increase production from 6,000 tons/year to 8,000 tons/year [15]. - P alcohol is a significant compound in the fragrance industry, used in various applications including personal care products and food flavoring [16].
