In the VAE emulsion market, CW VAE is a key term closely associated with Chuanwei Chemical's product portfolio. Public project documents indicate that Chuanwei Chemical has developed various VAE emulsion grades, including CW40-705, CW40-707, CW40-600, CW40-716, CW40-718, and CW40-907, while continuing to expand its production capabilities for conventional VAE, specialized VAE, and new VAE products.
SINOPEC CHONGQING SVW CHEMICAL CO., LTD. refers to Sinopec Chongqing Chuanwei Chemical Co., Ltd., an important chemical producer under Sinopec located in Chongqing, China.
The company's development is closely associated with Sichuan Vinylon Works. According to publicly available information, Chuanwei Chemical is built on a natural gas-based chemical industry and has gradually developed an integrated chemical product portfolio covering methanol, vinyl acetate, polyvinyl alcohol, VAE emulsion, vinylon fiber, and other products. Public company information indicates that Chuanwei Chemical has established significant industrial chain coordination among vinyl acetate, PVA, and VAE-related products.
For VAE emulsion production, this industrial structure is important. Vinyl acetate is one of the key monomers used in VAE emulsion production, while PVA can also serve as an important material in relevant emulsion polymerization systems. The company's presence across these related product categories provides a foundation for upstream and downstream industrial coordination.
VAE stands for Vinyl Acetate-Ethylene Copolymer. VAE emulsion is commonly known as a vinyl acetate-ethylene copolymer emulsion.
VAE emulsion is a water-based polymer dispersion system generally produced through the copolymerization of vinyl acetate and ethylene, among other components. Because water is used as the dispersion medium, VAE emulsion is widely used in various water-based adhesive, construction material, coating, and other industrial formulation systems.
Depending on the specific product grade and formulation system, VAE emulsion may differ in terms of:
It is important to emphasize that VAE emulsion is a broad product category, and different grades may have significantly different performance characteristics. Therefore, during procurement and application, the suitability of a product should not be judged solely by the term “VAE emulsion.” Specific technical parameters, application scenarios, and formulation requirements should also be considered.
CW VAE is a commonly used keyword in the market for the procurement and identification of Chuanwei Chemical's VAE products.
According to the environmental impact assessment documents for Chuanwei Chemical's 60,000-ton-per-year VAE expansion project, the product plan includes a number of representative VAE emulsion grades, including:
The project documents indicate that the planned production of conventional VAE emulsion products is 30,000 tons per year. The project also includes new and specialized VAE products, including anti-sagging grades, cable nonwoven foaming grades, high-end wood adhesive products, VAE for redispersible polymer powder, and VAE for cigarette-related applications.
From a product portfolio perspective, CW VAE is not a single product but a product system consisting of multiple grades and application directions.
For B2B buyers, key factors to consider when selecting a specific CW VAE grade generally include:
Different CW VAE grades may have different performance characteristics and application areas. Formal procurement should therefore be based on the latest TDS, SDS, COA, and sample test results provided by the manufacturer.
Chuanwei Chemical has continued to develop its VAE emulsion production capabilities in recent years.
In January 2025, the company's 60,000-ton-per-year VAE expansion project completed initial commissioning and produced qualified products. According to public reports, following completion of the project, Chuanwei Chemical's VAE production capacity reached 180,000 tons per year.
According to the product planning disclosed in the project documents, the 60,000-ton-per-year expansion project includes:
The conventional VAE emulsion product portfolio includes grades such as CW40-705, CW40-707, CW40-600, CW40-716, CW40-718, and CW40-907.
This indicates that Chuanwei Chemical's VAE development strategy involves not only expanding production capacity but also increasing the range of specialized products.
The specific application of VAE emulsion depends on the product grade and formulation system. Public information from Chuanwei Chemical indicates that its VAE products are associated with construction materials, adhesives, coatings, furniture, and other related applications.
Construction materials are an important application area for VAE emulsion.
VAE emulsion can be used in certain construction adhesives, architectural coatings, waterproofing materials, and other water-based construction material formulations. Depending on the formulation, VAE emulsion may primarily contribute to adhesion and film formation.
Public reports indicate that Chuanwei Chemical has developed products for applications such as construction tile adhesives and carried out technical optimization for related performance requirements.
For construction material manufacturers, product selection generally requires a comprehensive evaluation of:
VAE emulsion can be used in a wide range of adhesive formulations due to its water-based system and adhesion properties.
Potential application areas include:
Different end-use applications have different requirements for initial tack, final bonding strength, water resistance, flexibility, and film-forming performance. Therefore, the appropriate VAE grade should be selected according to the specific application.
VAE emulsion can also be used in certain water-based coating systems.
In coating formulations, the emulsion needs to be matched with pigments, fillers, dispersants, thickeners, and other additives. The final coating performance depends not only on the emulsion itself but also on the overall formulation design and application conditions.
Therefore, buyers should avoid determining whether a VAE emulsion is suitable for a particular coating system based on a single technical parameter.
Wood adhesives are one of the specialized application areas for VAE emulsion.
The VAE project documents of Chuanwei Chemical include the development of new products for high-end wood adhesive applications. For wood processing and furniture manufacturers, key performance factors typically include:
Different types of wood and manufacturing processes may also create different requirements for adhesive performance.
Based on publicly available information, industrial chain coordination is one of the key characteristics of Chuanwei Chemical's VAE business.
Vinyl acetate is one of the key raw materials used in VAE emulsion production. Chuanwei Chemical has long maintained production capabilities related to vinyl acetate, providing an upstream industrial chain foundation for its VAE business.
PVA is another important product of Chuanwei Chemical. The company's production capabilities in both PVA and VAE provide a foundation for product and industrial chain coordination.
As VAE production capacity has expanded, Chuanwei Chemical's product portfolio has gradually developed from conventional VAE emulsions toward new and specialized VAE products.
This direction reflects the broader development trend of the VAE emulsion industry, which is moving from simple capacity competition toward greater product differentiation and application specialization.
For overseas importers, adhesive manufacturers, construction material companies, and coating producers, the following factors should be carefully confirmed when purchasing CW VAE.
Products such as CW40-705, CW40-707, CW40-600, CW40-716, CW40-718, and CW40-907 should not be treated as directly interchangeable.
Buyers should confirm the appropriate grade according to the specific application.
Before formal procurement, buyers should confirm:
Specific technical parameters should be based on the latest official documents provided by the supplier.
Buyers should clearly identify whether the product will be used for:
Different end uses may require different technical characteristics from the VAE emulsion.
For bulk procurement, especially for formulation-based products, sample testing is recommended before formal purchasing.
Actual application performance can be affected by formulation design, equipment, temperature, processing methods, and other raw materials. Laboratory testing and pilot-scale validation are therefore important steps in product selection.
Overall, SINOPEC CHONGQING SVW CHEMICAL CO., LTD. has developed a solid industrial chain foundation based on its production capabilities and product portfolio covering vinyl acetate, PVA, and VAE.
