EVA (ethyl vinyl acetate) is a copolymer adhesive that can adhere to a variety of materials. Since this type of adhesive can be specially formulated for various applications, you can find many different types on the market.
EVA hot melt adhesives generally do not use water or solvents to acquire their adhesive properties, which allows them to set very quickly, have a long shelf life and perform well in a wide range of temperatures.
Ethylene promotes adhesion to non-polar substrates such as polyethylene and provides the mechanical strength, blocking resistance and solubility of the paraffin contained in the hot melt adhesive. Vinyl acetate, on the other hand, promotes adhesion to polar substrates such as paper and provides flexibility, adhesion and better performance at low temperatures. The formulation of the adhesive directly influences its properties.
For example, a higher proportion of ethylene in the formulation will give the EVA adhesive increased strength and resistance, while a higher amount of vinyl acetate will provide stronger adhesion to paper products and improve the flexibility of the adhesive. Formulations that contain higher amounts of vinyl acetate can also operate at lower temperatures and have a longer open time and slower cure time.
Although the properties of EVA adhesives vary according to their specific formulations, they generally adhere to the widest range of substrates and function in one of the widest ranges of temperatures for hot melt adhesives. In fact, EVA hot melt adhesives can operate at temperatures as low as -40 degrees Celsius and as high as 70 degrees Celsius depending on their formulation.
Thanks to their versatility, reliability and durability, EVA hot melt adhesives are used in a wide range of industries for a variety of applications. These industries include paper, mattress manufacturing, woodworking, assembly and automotive, to name a few.
However, the industry that most commonly uses EVA hot melt adhesives is perhaps the packaging industry. These adhesives are specifically formulated to adhere to waxes, paper, pulp and various water-based coatings. This makes them ideal for package labeling, carton sealing, assembly and paper processing.
Attention:
The HM adhesives should be used on any type of continuous edge banding machine.
Coating can be made either on the edge or on the section material.
The coated material is immediately placed in contact with the substrate and pressed with rolls.
(The temperature should be checked directly in the gluing system)
The supports and edges must be at ambient temperature(which should not be less than 15°C)
and the level of humidity should not exceed 10% in order to obtain a good bond.
