With the continuous development of the composite materials industry, hot melt adhesive films, as key materials, are increasingly used in various fields. Among them, the low temperature low melting point hot melt adhesive film, particularly EVA hot melt adhesive film, has achieved remarkable results in many industries due to its unique properties. The low temperature and low melting point characteristics of EVA hot melt adhesive films make them indispensable in certain specialized industries and processes. This article will introduce the product characteristics and application fields of low temperature low melting point EVA hot melt adhesive films.
Overview of EVA Hot Melt Adhesive Film
EVA hot melt adhesive film, the full English name being ethylene-vinyl acetate copolymer hot melt adhesive film, is made from the copolymerization of ethylene and vinyl acetate monomers. EVA is a versatile polymer material with a low melting point, making it an ideal choice for processes that require lower temperatures. The melting point of EVA hot melt adhesive film is approximately 70°C, placing it among the lowest in the hot melt adhesive film category. Due to its low melting point and excellent bonding properties, low temperature low melting point EVA hot melt adhesive film is widely used in industries with strict temperature control requirements.
Product Characteristics of Low Temperature Low Melting Point EVA Hot Melt Adhesive Film
The most prominent feature of low temperature low melting point EVA hot melt adhesive film is its low melting point, making it suitable for low-temperature applications or materials that require some degree of low-temperature resistance. The following are the key characteristics of low temperature low melting point EVA hot melt adhesive film:
Low Melting Point
EVA hot melt adhesive films are generally available in three melting point categories: 80°C, 90°C, and 110°C. The 80°C variant is the most commonly used. Its low melting point allows for quick bonding at lower temperatures during processing, reducing the need for temperature control in equipment, saving energy, and being well-suited for applications that require low temperature bonding.
Low Temperature Resistance
Low temperature low melting point EVA hot melt adhesive films can perform effectively at temperatures as low as -20°C. This low-temperature resistance makes these films ideal for products used in cold environments or winter products, such as sports shoes, wetsuits, and other cold-weather gear.
High Temperature Resistance
Although these films have a low melting point, they can withstand high temperatures up to around 80°C. This characteristic makes them suitable for applications where the temperature does not exceed this threshold. In environments with temperatures higher than 80°C, it is important to consider alternative adhesive films.
Environmentally Friendly and Odorless
One of the key benefits of low temperature low melting point EVA hot melt adhesive films is that they are environmentally friendly and odorless. These films meet environmental protection standards and do not produce any unpleasant smells during heating. They are widely used in industries with stringent environmental requirements.
High Bonding Strength and Excellent Tensile Properties
These films offer excellent bonding strength and tensile properties, allowing for strong and durable bonds between various materials. Their elasticity ensures that they can withstand the stresses involved in the composite processes of different materials.
Limited Water and Dry Cleaning Resistance
It is important to note that EVA hot melt adhesive films have limited water resistance and are not suitable for dry cleaning. If water resistance is required for an application, other adhesive films or protective layers may need to be considered.
Application Fields of Low Temperature Low Melting Point EVA Hot Melt Adhesive Film
Due to its low melting point and excellent performance, low temperature low melting point EVA hot melt adhesive film is widely used across many industries. Some of the primary applications include:
Shoe Materials Industry
EVA hot melt adhesive films are extensively used in the lamination of insoles, sports shoes, and skates. The low temperature low melting point hot melt adhesive film ensures efficient bonding during the shoe manufacturing process, even at lower temperatures.
Sporting Goods
In the sporting goods sector, especially for products like diving suits and running shoes, EVA hot melt adhesive films provide strong bonding while maintaining good elasticity. This helps ensure product comfort and durability.
Electronics Industry
The low temperature low melting point EVA hot melt adhesive film is used in the bonding of electronic components such as mobile phones, televisions, and household appliances. These films enable bonding at lower temperatures, minimizing the risk of damaging delicate electronic components during the manufacturing process.
Home and Building Materials
EVA hot melt adhesive films are widely used in bonding household items, furniture, wood products, and flooring materials. Their low temperature properties make them suitable for applications in environments that require lower temperature bonding.
Packaging Industry
In packaging, EVA hot melt adhesive films are used for bonding materials like cartons and packaging bags. The low temperature bonding properties make it ideal for packaging products that need to be sealed or bonded in low-temperature environments.
Medical and Craft Industries
EVA hot melt adhesive films are used in the manufacturing of medical products and handicrafts. The films provide stable bonding strength, are environmentally friendly, and meet health and safety standards.
Conclusion
Low temperature low melting point EVA hot melt adhesive films are a versatile material used across various industries, including shoe materials, sporting goods, electronics, home building materials, and packaging. These films not only provide superior bonding results at lower temperatures but also offer important characteristics such as odorless performance, environmental friendliness, and elasticity. As technology advances, the application of EVA hot melt adhesive films is expected to expand, supporting product innovation and development in even more sectors.
