Use of Vinyl acetate-ethylene copolymer emulsion

VAE-Vinyl acetate-ethylene copolymer emulsion

1. Market segmentation of VAE emulsion application fields, mainly distributed in the fields of adhesives (41%), external wall insulation (25%), building waterproofing (13%) and textiles (8%).

1.1 Adhesives Adhesives are the most widely used and demanded fields of VAE emulsions, and are mainly subdivided into packaging, woodworking and cigarette adhesives. Packaging is mainly divided into paper products, lamination and PVC glue, and VAE emulsion is still showing a growth trend in the packaging industry. VAE emulsion has been widely used in the wood glue industry, and the demand for wood glue has grown by a large margin. The use of VAE emulsion in the cigarette rubber industry has been very mature.  

1.2 External thermal insulation of external walls Due to China’s requirements for environmental protection and energy conservation in buildings, the implementation of external thermal insulation systems for external walls is mandatory in the construction industry, so that the demand for VAE in this industry maintains a rapid growth. The amount of VAE used for external insulation of external walls has accounted for more than 25%.

1.3 Building waterproof coatings, the large-scale application of VAE emulsions in the waterproof field is a major feature of China’s VAE emulsion industry, because from the application of the world’s VAE emulsion industry, VAE emulsions are rarely used in waterproof coatings, which may be It is the product of China’s rapid economic development. VAE emulsion is mainly used for indoor waterproofing.

1.4 Textile/non-woven textile printing and bonding VAE emulsions have been widely used in the United States, Europe, Taiwan, China and other places, and now the textile industry in these areas is gradually transferred to China. At present, the demand for VAE emulsion in China’s textile industry is about 8%.

1.5 Others VAE emulsion is mainly used in the above fields, but also used in carpet adhesive, paper coating, cement caulking mortar, PVC floor glue, fruit glue, handicraft processing, three-dimensional oil painting and air filter. With the enhancement of domestic environmental awareness and the improvement of application technology, the application of VAE in some new fields is expanding.

Note: Both type 716 and Enhanced Specialty Composite Adhesive

can be used to bond shoe uppers or soles. Generally, plasticizers need to be added, and the viscosity should be adjusted according to the customer’s machine.
