Core Viewpoint - Changhua Chemical has successfully applied carbon dioxide polyether in the trial production of continuous soft foam, marking a significant technological breakthrough in the chemical industry [2][3]. Group 1: Technological Advancements - The company utilizes industrial waste CO2 as a raw material, employing low-temperature and low-pressure catalytic technology to produce carbon dioxide polyether (Carnol®) [2]. - The production process is considered internationally advanced, offering higher safety compared to existing domestic high-temperature and high-pressure methods [2]. - The resulting carbon dioxide-based foam exhibits excellent hydrolysis resistance, yellowing resistance, and mechanical properties, making it suitable for various applications in the automotive and home furnishing sectors [3]. Group 2: Project Investment and Capacity - The total investment for the carbon dioxide polyether and high-performance polyol project is approximately 586.25 million yuan, located in Lianyungang City [3]. - The project is divided into two phases, with the first phase aiming to establish production capacities of 80,000 tons/year for carbon dioxide polyether and 300,000 tons/year for polyether polyols, among others [3]. - Upon full completion, the project is expected to achieve an annual production capacity of 1.06 million tons of carbon dioxide polyether, 300,000 tons of polyether polyols, and 720,000 tons of polymer polyols [3]. Group 3: Strategic Partnerships - Changhua Chemical's carbon dioxide polyether technology is derived from Econic Technologies, a UK-based company founded by Dr. Charlotte Williams [4]. - A strategic cooperation agreement was signed between Econic Technologies and Changhua Chemical in June 2022 to promote the localized production of carbon dioxide polyether using the low-temperature and low-pressure preparation process [4].
