VAE Emulsion CW40-600

VAE emulsion, short for Vinyl Acetate Ethylene copolymer emulsion, is a versatile material widely used in various industries. Its unique properties make it an essential ingredient in the manufacturing of adhesives, paints, coatings, and construction materials.   VAE Emulsion (CW 40-600 & DA-117) is a water-based dispersion composed of vinyl acetate and ethylene monomers. This copolymerization results in a high-quality emulsion that offers outstanding adhesive properties, excellent flexibility, and exceptional bonding strength. VAE Emulsion acts as a binder, providing exceptional stability and enhancing the performance of various end products.   One of the notable applications of VAE Emulsion is in the production of adhesives. Due to its excellent adhesion properties, VAE Emulsion is widely used in industries such as woodworking, paperboard lamination, and packaging. The high bonding strength and flexibility of VAE Emulsion enable it to deliver durable and long-lasting adhesion, ensuring the integrity of bonded surfaces.   In the world of architectural coatings, VAE Emulsion plays a crucial role as a binder. It is known for its exceptional film-forming abilities, providing coatings with excellent weather resistance, water repellency, and durability. Moreover, VAE Emulsion enhances the color stability and gloss of coatings, resulting in a visually appealing finish. Its versatility allows it to be used in various coating systems, including exterior paints, interior wall paints, and textured coatings.   Construction materials also benefit from the extraordinary properties of VAE Emulsion. It can be combined with cement, gypsum, or other powders to produce VAE Redispersible Powder. When used in tile adhesives, grouts, and self-leveling compounds, VAE Redispersible Powder enhances workability, water retention, and adhesion strength. This combination ensures reliable performance in demanding applications, such as tile installation and repair.   While the quality of the product itself is essential, exceptional service adds significant value to the overall customer experience.

Vinyl acetate is a colorless flammable liquid with a strong odor. Its vapor is irritating to the eyes. It is insoluble in water but soluble in most organic solvents. Vinyl acetate monomer(VAM) is flammable and reacts rapidly with chlorine, bromine, and ozone. There are two production process routes for vinyl acetate monomer: the ethylene method and the acetylene method. The acetylene method can be divided into a liquid phase method and a gas phase method, and the ethylene method can also be divided into a liquid phase method and a gas phase method.   Acetylene gas phase method: desulfurized and dephosphinated calcium carbide acetylene and acetic acid are used as raw materials, the catalyst is zinc acetate-activated carbon (15:100), and a promoter is added. The reaction temperature is 170~200℃, the pressure is atmospheric pressure, and the space velocity is 200~400/h. Reaction results: acetic acid single-pass conversion rate is 25~40%, acetylene single-pass conversion rate is 12~16%. The selectivity of VAM is 92~96% for acetylene and 95~98% for acetic acid. The total yield of VAM is 97~98% for acetic acid and 92~96% for acetylene.   The catalysts for the ethylene gas phase process are mainly Pd-Au, Pd-Pt and Pd-Cd supported catalysts, and the carriers are mainly silica gel and alumina. The two main factors affecting the catalyst are the coordination ability of Pd and the ability of acetic acid or acetate to oxidize Pd(0) to Pd(II). The single-pass conversion rate of ethylene in this process is 8~10%, the single-pass conversion rate of acetic acid is 8~20%, and the VAM ( CW 40-600 & ECO VAE 1608) selectivity based on ethylene is 90~94%.   In the past few years, the acetylene process has been gradually replaced by the ethylene process due to the high cost of raw materials. However, with the continuous rise in oil prices, the acetylene process has regained economic vitality, especially the acetylene process using natural gas as raw material. At present, the acetylene process still occupies an important position in China. The ethylene gas phase process occupies a dominant position in the market due to its good processability and economic performance. At present, the ethylene production technology in China accounts for more than 55% of the total national production capacity.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.

VAE stands for Vinyl Acetate Ethylene emulsion. It is a type of emulsion polymer made by the copolymerization of vinyl acetate (VA) and ethylene monomers. The resulting copolymer is dispersed in water to form an emulsion.   The composition of VAE emulsion ( CW 40-718) typically consists of: 1. Vinyl Acetate (VA): This monomer, also known as vinyl ethanoate, provides the adhesive and film-forming properties to the emulsion. 2. Ethylene: Ethylene is a gaseous monomer that is copolymerized with vinyl acetate to improve the strength, flexibility, and resistance properties of the resulting polymer. 3. Emulsifiers: Emulsifiers are used to stabilize the emulsion and prevent the coagulation or separation of the polymer particles in water. They help in the formation of a stable, uniform emulsion. 4. Water: Water is the main component of the emulsion, serving as the dispersion medium for the polymer particles.   ElephChem VAE emulsion is commonly used in various applications such as adhesives, coatings, textiles, paper coatings, and construction materials. Its properties, such as good adhesion, flexibility, and water resistance, make it suitable for a wide range of applications.
