Anhydride Modified Ethylene-Vinyl Acetate Copolymer as Adhesive for Multi-layers
COACE's main products are compatibilizers, tougheners and functional additives, which are used in: modified plastics, wood-plastic profiles, low-smoke halogen-free flame-retardant cables, PP extruded sheets, PE extruded sheets, and anti-corrosion pipes Coatings, hot melt adhesives, photovoltaic film additives and other fields, among which special products such as nylon ultra-low temperature toughener, polyester compatible toughener, alloy compatibilizer have reached the domestic advanced level.
Coace® K2G is an anhydride modified ethylene-vinyl acetate copolymer, which offers excellent adhesion to foil, paper and other polar substrates.
Anhydride-modified EVA copolymers are created by grafting maleic anhydride or other reactive groups onto the EVA backbone. This chemical modification infuses polar functionalities into the non-polar EVA, improving its adhesive qualities. The modification procedure typically employs a reactive extrusion or chemical grafting technique to achieve a homogeneous distribution of anhydride groups throughout the copolymer.
The basic mechanism by which these adhesives work is the creation of covalent bonds and strong interfacial contacts between the adhesive and the substrates. The anhydride groups react with functional groups on the surfaces of different materials, such as hydroxyl, amine, or carboxyl groups, to form strong, long-lasting connections. This interaction considerably increases the adhesion strength and stability of multilayer structures.
1. Enhanced Adhesion: One of the most notable features of anhydride modified EVA copolymers is their improved adherence. The presence of anhydride groups allows for strong bonding with a variety of substrates, including metals, polymers, glass, and composites. This ensures that the glue may form strong, dependable multi-layered structures.
2. Versatility: Anhydride modified EVA adhesives are extremely versatile, capable of attaching a wide range of surfaces. Because of their adaptability, they can be used in a wide range of industries, including packaging, automotive, electronics, and construction. The ability to smoothly connect several materials is a significant advantage in multi-layer applications.
3. Thermal Stability: These adhesives have exceptional thermal stability, meaning they retain their adhesive properties throughout a wide temperature range. This feature is critical for applications that are subjected to variable heat conditions, ensuring that the adhesive remains effective even in harsh situations.
4. Mechanical Strength: Anhydride-modified EVA copolymers have great mechanical strength, including tensile and peel strength. This ensures that the bonded materials can sustain mechanical loads while maintaining their integrity over time, making them appropriate for demanding applications.
5. Chemical Resistance: The anhydride treatment enhances the chemical resilience of the EVA copolymer. This characteristic is critical for situations where the adhesive may be exposed to chemicals, solvents, or oils, as it ensures long-term durability and functionality.
