Ethylene-vinyl acetate copolymer (EVA) glue is a thermoplastic styrene-butadiene rubber, rosin modified resin, petroleum resin and solvent-based adhesive, designed for bonding EVA materials. It is also suitable for many other materials, such as wood, leather and foam (EPE), and is popular for its excellent bonding effect and long-term aging stability. This article will explore the characteristics of EVA glue, use and use precautions.

Features of EVA glue

EVA glue has many advantages:

  1. Wide applicability: In addition to being particularly suitable for EVA materials, it can also be used for bonding between a variety of different materials.

  2. Excellent bonding ability: The glue can form a strong bonding force, ensuring long-term aging stability and long-lasting bonding effect.

  3. Simple operation process: without pretreatment, direct application can quickly complete the bonding work, greatly improving the production efficiency.

  4. Excellent flexibility and impact resistance: Even under extreme conditions, it can maintain good cushioning properties and is not easy to fall off or chip.

  5. One-component system: Compared with other two-component glues, EVA glue is easier to use and reduces the risk of misproportioning.

  6. High transparency: For products with certain requirements for aesthetics, EVA glue can maintain the appearance quality of the product while bonding.

Steps to use EVA glue

When using EVA glue, follow these steps:

  1. Surface preparation: first thoroughly remove the grease, dust and other impurities on the surface of the object to be bonded to ensure the bonding effect.

  2. Apply glue: Apply an appropriate amount of EVA glue evenly on at least one surface, and wait about 5 to 10 minutes until the adhesive film is slightly dry and does not feel sticky.

  3. Bonding and compaction: Align the two surfaces and apply appropriate pressure to promote better contact.

  4. Fixed and dry: placed one to two hours to allow the initial curing of the glue, 24 hours to reach the appropriate use of the state, and forty-eight hours is its maximum bonding strength.

Precautions

In the process of using EVA glue, the following points should be paid attention to to ensure safety and best performance:

  • Flammability: EVA glue is flammable because it contains organic solvents. Storage and transportation must be carried out in strict accordance with the relevant specifications to prevent fire risks.

  • Ventilation: For health and safety reasons, it should be used in a well-ventilated environment to avoid inhaling harmful vapors.

  • Keep away from fire sources: Keep away from open flames or other ignition sources during operation to prevent accidents.

  • Drying time: Adjust the drying time according to the actual environment, avoid moving or loading heavy objects in advance, so as not to damage the bonding effect.

Application areas

EVA glue plays a key role in many industries due to its practicality and versatility:

  • Household appliances: EVA glue is often used to bond plastic parts when manufacturing the shell or components of household appliances.

  • Hardware tools: used for the assembly of the handle or other parts of the tool to enhance the grip and durability.

  • Toys: In the production of children's toys, EVA glue ensures the stability and safety of the toy structure.

  • Crafts: In the process manufacturing industry, it is used to bond light materials and enhance the overall texture of the finished product.

  • Travel supplies: used in the manufacture of travel accessories such as suitcases and backpacks to increase their durability and bearing capacity.

  • Stationery: In stationery manufacturing, such as folders, photo albums, etc., EVA glue provides a reliable bonding solution.

  • Cosmetic packaging: in the cosmetics industry, used for the assembly of bottles, boxes and other packaging.

How to choose the right dispensing needle for the dispensing machine?

How to choose the right dispensing needle for the dispensing machine?

The glue dispenser is also called glue coating machine, glue dripping machine, glue filling machine, etc. It is an automatic machine that specially controls the fluid and drips and coats the fluid on the surface of the product or inside the product. It can realize three-dimensional and four-dimensional path glue dispensing, precise positioning, precise glue control, no wire drawing, no glue leakage and no glue dripping. The glue dispenser is mainly used for the precise point, injection, coating and drip of glue, paint and other liquids in the product process to the precise position of each product. It can be used to achieve dot, line, circle or arc. How to choose the right dispensing needle for the dispensing machine? The following guidelines are for reference: 1. Small point: small size dispensing needle, low pressure, short time. 2. Big point: large dispensing needle, greater pressure, longer time. 3. thick glue: oblique needle, large pressure, according to the need to set the time. 4. Aqueous liquid: small size needle, less pressure, set time as needed Fluids requiring special settings: 1. Instant glue: use safety piston and Teflon-lined metal needle for water-based instant glue, use tapered needle for thick instant glue, and use PP needle if flexibility is required. 2.UV glue: use amber syringe, white piston and inclined needle (can shield UV). 3.
