HOTMELT
WHAT ARE HOTMELT ADHESIVES?
Hotmelt adhesives are thermoplastic resin-based adhesives that melt and become liquid when heated and solidify rapidly when cooled, providing strong bonding. Hotmelt adhesives are known for their short cure times and ease of use. Thanks to these features, they speed up production processes and increase efficiency.
Hotmelt adhesives are made of various thermoplastic polymers and when heated to the melting temperature, they become liquid and spread easily on the application surface. When cooled, they solidify and form a high-strength bond. These adhesives are preferred in many industries because they provide excellent adhesion on different surfaces.
Hotmelt adhesives are commonly used in many industries such as packaging, textile, automotive, electronics and woodworking.
Advantages and Usage Areas of Hotmelt Adhesives
Hotmelt adhesives have a wide range of uses, offering many advantages. One of the most important advantages of these adhesives is their fast adhesion and curing time. This feature speeds up production processes and saves time and costs. Especially in sectors where mass production is carried out, hotmelt adhesives provide great efficiency.
Hotmelt adhesives also offer superior properties in terms of flexibility and durability. These adhesives are compatible with various materials and provide resistance to impact and vibration thanks to their flexible structure. This feature makes hotmelt adhesives preferred in the automotive and electronics sectors. In addition, these adhesives can be used safely even in harsh environmental conditions because they are resistant to water, moisture and chemicals.
Another important advantage of hotmelt adhesives is their environmentally friendly and solvent-free formulation. These adhesives are safer for both the environment and human health thanks to their low VOC emissions. In addition, features such as recyclability and biodegradability make hotmelt adhesives an environmentally sustainable option.
Hotmelt adhesives offer a wide range of material compatibility. They provide effective bonding to metal, plastic, fabric, leather, wood and many other materials. This versatility makes hotmelt adhesives an indispensable option in many industries. Especially in applications where different materials need to be bonded, hotmelt adhesives provide excellent results.
Finally, hotmelt adhesives offer a cost-effective solution. Despite their high performance, hotmelt adhesives are generally low-cost, which can save costs on large-scale projects. Especially in industries with large production volumes, hotmelt adhesives offer an economical solution.
HOTMELT ADHESIVE TYPES
- EVA (Ethylene Vinyl Acetate) based adhesives, EVA (Ethylene Vinyl Acetate) based adhesives are frequently preferred adhesive types in the industry due to their versatile structures and wide compatibility. EVA is a widely used base polymer.
- PSA (Pressure Sensitive Adhesive) basedadhesives are preferred in many applications that require high performance. PSA based adhesives maintain their flexibility even at low temperatures. This feature allows the adhesive to perform in cold conditions without cracking or breaking. Their high heat resistance makes these adhesives ideal for high temperature applications. They do not lose their adhesive properties even when exposed to high temperatures.
- Polyolefin-based adhesives are general purpose adhesives used in a wide range of industrial applications. Polyolefin-based adhesives are general purpose adhesives that can be used in a wide range of applications. They offer a balance of durability and performance. They have moderate temperature resistance and generally perform effectively at low and moderate temperatures.
- APO adhesives have a soft, sticky and flexible structure. These properties are especially advantageous in applications requiring elasticity and flexible adhesion. They offer long open times, which provides greater flexibility during application. They also offer strong adhesion to surfaces.
Where Are Hotmelt Adhesives Used?
In the packaging industry, these adhesives are widely used for bonding cardboard boxes, labels and packaging materials.
In shoe manufacturing, hot melt adhesives play a critical role in bonding the sole and upper materials. Their flexible structure ensures that the shoes are long-lasting and comfortable.
In the textile industry, hotmelt adhesives are used to join fabrics, leather and other woven products. It provides strong adhesion without damaging textile products and increases the comfort of clothing products thanks to its flexible structure. In addition, hotmelt adhesives are also preferred in outerwear and sports equipment because they are resistant to water and moisture.
In the automotive industry, hotmelt adhesives are used to assemble interior and exterior trim parts. Their flexibility, impact resistance and high temperature resistance make them an ideal solution for automotive applications.
In the electronics and white goods industry, hotmelt adhesives are used to assemble various components. Thermal resistance and electrical insulation properties make these adhesives suitable for electronic devices.
