What is EVA glue?

EVA glue is a type of hot-melt adhesive made from ethylene-vinyl acetate (EVA) copolymer. It boasts strong, flexible, and waterproof bonding properties, making it suitable for bonding various materials such as wood, metal, glass, ceramics, and certain plastics. It is widely used in industries like packaging, footwear, automotive, and crafts due to its durability and resistance to temperature fluctuations. Below is a detailed introduction to EVA glue:

Basic Properties

• Chemical Composition: EVA glue primarily consists of ethylene-vinyl acetate copolymer. By adjusting the ratio of ethylene to vinyl acetate, EVA products with varying properties can be created. Generally, when the vinyl acetate content is below 20%, EVA behaves more like a plastic; when the content is between 40% and 70%, it exhibits rubber-like properties.
• Physical Properties: EVA glue is typically solid at room temperature. When heated to a certain temperature, it melts into a liquid. Once cooled below its melting point, it solidifies again. It features high cohesion, low melt surface tension, and strong adhesive properties, offering good bonding performance on most materials. Additionally, it has excellent resistance to chemicals, heat, weather, and electricity.

EVA Glue Advantages

• Strong Adhesion: EVA glue can bond a wide range of materials, including porous and difficult-to-bond surfaces, with strong initial adhesion and high bonding strength.
• Excellent Flexibility: It maintains the flexibility of the bonded material, making it ideal for applications requiring bendable or movable parts. It provides reliable bonding performance even under dynamic stress.
• Waterproof and Moisture-Resistant: Its closed-cell structure prevents water absorption, making it suitable for marine, outdoor, and moisture-prone environments. It remains stable in contact with water and retains its adhesive properties.
• Resistant to Temperature Fluctuations: It can withstand temperatures ranging from -40°F to 160°F, making it suitable for use in various climate conditions.
• Environmentally Friendly: EVA glue is free of solvents and volatile organic compounds (VOCs), posing no harm to the environment or human health during use.

Applications

• Packaging Industry: EVA glue is used for carton sealing, label bonding, and packaging foam inserts. It secures packages, enhances their appearance, and protects products during transportation.
• Footwear Industry: It is applied in the production of shoe soles, particularly for bonding elastic and shock-absorbing soles. It ensures strong adhesion and durability, extending the lifespan of footwear.
• Automotive Industry: EVA glue is used to bond interior components such as dashboards, door panels, and seats. It provides high-strength bonding and meets automotive safety and reliability requirements.
• Construction Industry: It is used in insulation and waterproofing materials, effectively preventing heat loss and water infiltration in buildings. It contributes to energy efficiency and structural durability.
• Craft and DIY Projects: EVA glue is ideal for bonding materials like wood, paper, fabric, and plastic in craft making and DIY projects. It enables creative designs and durable bonding results.

Comparison with PVA Glue

PVA glue, made from polyvinyl acetate, is water-soluble, non-toxic, and dries clear. It is commonly used for woodworking and paper crafts. EVA glue outperforms PVA glue in flexibility, waterproofing, and heat resistance, making it suitable for industrial and outdoor applications. However, PVA glue is preferred for indoor use on porous materials due to its safety and ease of use.

Removal Methods

• Mechanical Removal: After softening the glue with a heat source like a hairdryer, gently scrape it off using a plastic scraper.
• Solvent Application: Apply organic solvents such as acetone or isopropyl alcohol to dissolve residual glue. After the solvent acts on the glue, wipe it away with a cloth.
• Heat Treatment: Apply heat to reduce the glue’s adhesion strength, then carefully peel off the bonded material to remove the glue.
