What Are Mainly Applications of Ethylene Acrylic Acid

Packaging. EAA is widely used in the production of various types of food packaging films and bags. Its high transparency and heat sealing properties make it an ideal choice for displaying food and maintaining food freshness.

Powder coating. EAA powder can be sprayed on the surface of materials such as pipes, steel, non-woven fabrics, etc. as an anti-corrosion material.

Hot melt adhesive. High-performance and high-MI EAA can produce hot melt adhesives for difficult-to-bond materials.

Aqueous solvents. EAA with high AA content and high MI can be dissolved in hot alkaline solutions under appropriate reaction conditions, and can be used to prepare water-based adhesives for clothing and clothing materials.

One of the main formulas for inks and coatings.

Degradable and environmentally friendly materials.

Application of EAA in the automotive industry

‌Engine parts‌. EAA copolymer can be used to manufacture engine seals and insulation materials to improve engine performance and durability.

‌Chassis parts‌. EAA is used to manufacture chassis suspension systems and shock absorbers to improve vehicle comfort and handling.

‌Body parts‌. EAA can be used to manufacture interior and exterior trims of the vehicle body, such as sealing strips, gaskets, and dashboard covers. These parts need to have good weather resistance and flexibility to adapt to different climatic conditions and usage environments. ‌

Application of EAA in the construction industry

‌Waterproof materials‌. EAA Ethylene Acrylic Acid has good waterproof properties and can be used to manufacture waterproof membranes, waterproof coatings, etc., for waterproofing of roofs, walls, and other parts of buildings.

‌Sealing materials‌. EAA is widely used in building sealing materials, such as sealants, sealing strips, etc., for sealing joints of doors, windows, pipes, etc. to prevent moisture penetration‌.

‌Anti-corrosion materials‌. EAA’s chemical resistance makes it also important in anti-corrosion materials. It can be used to manufacture anti-corrosion coatings, anti-corrosion tapes, etc. to protect buildings from corrosion‌.

‌Insulation materials‌. EAA’s thermal insulation properties make it also have certain applications in insulation materials. It can be used to make insulation films, insulation boards, etc. to improve the insulation effect of buildings. ‌Adhesive materials‌. EAA has good adhesive properties and can be used for bonding treatment of buildings, such as tile pasting, stone pasting, etc. ‌

‌Application of EAA in medical supplies

‌Syringe needle protection cap‌. The high transparency and softness of Ethylene Acrylic Acid copolymer make it an ideal material for manufacturing syringe needle protection caps, which can provide good protection and have good sealing properties.

‌Medical gloves and surgical gowns‌. The chemical resistance and softness of EAA plastic make it perform well in medical gloves and surgical gowns, which can resist various chemical disinfectants while providing a comfortable wearing experience.

‌Specific applications of EAA in the packaging industry

Ethylene acrylic acid copolymers are widely used in flexible packaging, such as laminated tubes, condiment bags and pouches, aseptic packaging, meat and cheese packaging. Extrusion coating produces beverage cartons, toothpaste tubes, cable shielding layers, etc.

‌Adhesive layer of composite film‌. EAA can be used as the adhesive layer of composite film for the packaging of food, medicine and cosmetics, providing good sealing and puncture resistance. ‌Coating materials‌. EAA can be used as a coating material for surface treatment of metal, paper and fabric to improve its water resistance and chemical resistance.

‌Hot melt adhesive or pressure sensitive adhesive. EAA can be used as a hot melt adhesive or pressure sensitive adhesive to bond different materials such as plastics, metals and wood ‌Fibers and fabrics. EAA can be used to produce fibers and fabrics to provide softness and durability.

Application of EAA in agricultural films

Ethylene acrylic acid copolymer has good heat resistance and weather resistance, can resist corrosion from acid, alkali and other solvents, and has excellent electrical insulation properties, which can play a role in isolating current. These characteristics enable ethylene acrylic acid copolymer to provide good protection and isolation effects in agricultural films, extend the service life of the film, and reduce damage caused by environmental factors.

In addition, ethylene acrylic acid copolymer can also be blended with other materials to further improve its performance. For example, blending with starch-based materials can prepare degradable agricultural mulch films, which have environmental advantages in agricultural applications and can reduce soil pollution. ‌

Application of EAA in environmentally friendly degradable materials

EAA can be blended with starch-based materials to produce degradable plastics. This type of plastic can decompose quickly in the natural environment, helping to reduce the pollution of plastic waste to the environment.

The application areas of EAA in environmentally friendly degradable materials include packaging, agricultural mulch, disposable tableware, etc. These products can degrade quickly after use, reducing the burden on the environment.

What Are Excellent Properties of Ethylene Acrylic Acid Copolymer

FAQs of Ethylene Acrylic Acid EAA Resin

1. What are the differences between EAA and EVA?

They both are ethylene copolymers, but they differ in their polar monomers. EAA uses acrylic acid as its polar monomer, while EVA uses vinyl acetate.

Adhesive properties. EAA has significantly stronger adhesion to metals (especially aluminum foil) than EVA, and the bond is more durable and resistant to environmental stress.

Corrosion resistance. EAA contains carboxyl groups, providing better barrier properties against substances like greases, but these carboxyl groups may make it more sensitive to certain corrosive environments. EVA offers more balanced environmental resistance.

Application focus. EAA is primarily used in multilayer composite structures requiring extremely strong adhesion. EVA is more widely used in foaming, injection molding, and photovoltaic encapsulation.

2. What are the main differences between EAA and EMAA?

EAA has higher polarity and adhesion strength due to acrylic acid’s higher reactivity, while EMAA generally provides better toughness and lower melting points.

3. What are the main processing methods for Ethylene Acrylic Acid?

Extrusion coating: EAA granules are melted and directly coated onto a substrate (such as aluminum foil, paper, or plastic film) like glue to form a multilayer composite structure.

Co-extrusion: EAA is used as an adhesive layer in the production of multilayer films or sheets, extruded together with other resins (such as LDPE, PP, nylon, EVOH).

4. Is EAA resin compatible with other polymers?

Yes, EAA is compatible with polyethylene (PE), polypropylene (PP), ethylene methyl acrylate (EMA), and other copolymers. It’s often used as a tie-layer or compatibilizer in multilayer structures.

5. How to choose the right Ethylene Acrylic Acid EAA grade?

When choosing EAA, consider the following key parameters:

Acrylic content: Higher content results in better adhesion, transparency, and toughness, but lower rigidity and melting point.

Melt index: High MI grades are suitable for thin-layer coatings. Low MI grades have higher melt strength and are suitable for thicker coatings or co-extrusion.

Main applications: Select the appropriate EAA grade based on whether you are using it for extrusion coating, co-extrusion, or powder coating.

6. What are the major EAA manufacturers?

DOW: One of the leaders in this field, with a very comprehensive product range.

ExxonMobil: Another major supplier, offering a variety of EAA grades.

SK: A South Korean company with a significant presence in the Asia-Pacific market.
