Happy May Day 2024! Safety first. Let’s give praise and support to the achievements made in China’s chemical technology and equipment sector. **********************【Ten Years of Progress in Chemical Equipment】A continuously updated summary post is available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Forum Website) ***************** In May 2024, Sinopec Chongqing Chuanwei Chemical Co., Ltd. (hereinafter referred to as Chuanwei Chemical) successfully produced the first batch of high-performance VAE (vinyl acetate-ethylene copolymer emulsion) products tailored to meet customer needs, filling a gap in China’s market for such products used in high-end waterproof coatings. Two years ago, a key customer in the domestic waterproof coating industry expressed a need for high-performance waterproof VAEs, and at that time only one foreign company was capable of meeting this requirement. In response to the high-end demands of the industry market, Chuanwei Chemical has made full use of its integrated capabilities in production, sales, research, and application. Its R&D team spent over a month on-site at customers’ factories to gain a thorough understanding of their specific requirements. During the research, development, and production phases, technicians traveled back and forth between the customer’s factories, the company’s laboratories, and the production sites. Through more than 200 pilot tests and 16 industrial-scale trials, they continuously optimized the manufacturing processes and addressed specific challenges, thereby improving product quality. At the beginning of this year, a significant breakthrough was achieved: a new product was developed through independent research and production, one that meets all three stringent requirements of stability, high strength, and water resistance. This product is used as a waterproof coating for building roofs, kitchens, bathrooms, and other areas. To date, this new product has passed multiple trial tests in the customer’s factory, with all its specifications meeting the performance requirements of high-end waterproof VAE products. A first batch of orders has been placed with the customer, and other factories in China will also start using this product in the future.

As the application areas for these products continue to expand, along with **increased efforts in environmental monitoring, there is growing attention toward environmentally friendly products. As unique eco-friendly products, the market for VAEs is expanding steadily, with demand from end-users on the rise. In 2022, Sichuan Wei Chemical’s project to increase its annual production capacity of 60,000 tons of VAE (vinyl acetate-ethylene copolymer emulsion) was approved by Sinopec. This marks another expansion of VAE production capacity by Chuanwei Chemical, following the launch in 2021 of a new facility with an annual production capacity of 60,000 tons of VAE. This expansion project is set to come online in 2023, bringing Chuanwei Chemical’s total VAE production capacity to 180,000 tons, thereby making it one of the domestic manufacturers with the largest VAE production capacity in the country. In 2022, Sichuan Wei Chemical’s project to increase its annual production capacity of 60,000 tons of VAE (vinyl acetate-ethylene copolymer emulsion) was approved by Sinopec. This project is one of the key initiatives for Chuanwei Chemical to further expand its VAE production capacity, following the launch in 2021 of a facility with an annual production capacity of 60,000 tons of VAE. In 2023, the capacity expansion project for Sichuan Weihe Chemical’s annual VA production of 60,000 tons began with site preparation and entered the construction phase, with completion and operation expected by the end of 2024. It is understood that once the project is completed, Chuanwei VAE’s total production capacity will reach 180,000 tons per year. The construction of this project will further accelerate the upgrade of Chuanwei VAE’s production capacity, enhancing the competitiveness of its VAE products in the central and western regions of China. It will also enable the company to become one of the domestic manufacturers with the largest VAE production capacity.
