Working on more sustainable hotmelt adhesives.

We are living in a world where people are more aware of our planet and our future. We are proud to say, Protechnic, we are part of it. Our R&D department keeps searching for more sustainable and Eco-friendly adhesive materials. We have already succeeded to use some bio-based material. Today, we are even more driven to work in this direction.

What is a Thermoplastic Adhesive Film?

Thermoplastic adhesive film, commonly known as hotmelt adhesive film, is typically presented in the form of a roll. This adhesive solution can be manufactured using different techniques, resulting in either monolayer or multi-layer structures. 

  • Monolayer Thermoplastic Adhesive Film: This film consists of a single layer of adhesive material. 
  • Multi-layer Thermoplastic Adhesive Film: This film combines up to 5 layers coextruded into a single film.  

Examples include: 

  • 3-layer ABA films (Adhesive+Barrier+Adhesive)  
  • 2-layer AB films (Adhesive+Barrier) or 2-layer AA films (Adhesive+Adhesive)

For foam materials, selecting the right adhesive solution is crucial for achieving efficient and sustainable bonding results. One versatile option is thermoplastic adhesive in roll, which effectively bonds various materials, including foams and other technical substrates. In this article, we will explore the important role that this type of adhesive plays in various applications using these materials.

The Versatility of Thermoplastic Adhesives

Thermoplastic adhesives shows versatility by creating durable bonds across different types of materials, such as foams, 3D spacers, felt, non-wovens, technical textiles, or leather. This bonding addresses diverse manufacturing needs, with net, film, and web structures contributing to the improvement of applications in automotive, upholstery, footwear, leather goods, composites, building, and more. Roll-to-roll lamination method allows very low waste and clean results, 1 meter of adhesive equals to 1 meter of laminated material.

Automotive manufacturers have specific needs when it comes to assembling materials. As the market evolves, the need for versatile and sustainable bonding solutions becomes essential. In addition, car interior becomes increasingly customized.

This is where thermoplastic adhesive in roll comes into play.

Thermoplastic adhesive able to bond any material in automotive

Whether you’re working with leather, alcantara, microfiber, PVC, PU artificial leather, foams or technical non-wovens, hotmelt adhesives in roll ensures a seamless and durable bond allowing the best and lasting comfort for the end user. Thermoplastic adhesive provides a consistent and durable bonding. It plays an active role in stabilizing materials so the shape of the part remains the same through time.

Dry lamination is a technique employed in both automotive and industrial applications to bond two or more flexible substrates without the use of solvent-based adhesives or liquids. The adhesive utilized in this process often comes in roll form, which can have various structures like webs, films, or nets.

Using a roll-to-roll method, dry lamination facilitates quick bonding of different substrates. The bonding between the laminated layers is primarily achieved through thermoplastic adhesives such as polyolefin, polyester, co-polyester, co-polyamides, TPU, and specialty blend polymers.

For this roll-to-roll technique, the production line must be equipped with rollers to accommodate both the film or web and the various substrate layers. The thermoplastic adhesive is placed between these layers, and a laminating calender—with adjustable heat and pressure settings—ensures the materials bond correctly.

What is a Hot Melt Adhesive Net ?

In the adhesive market, “hot melt” (HMA) often refers to solid glue. There are several forms of hot melt adhesives, which can be categorized based on their physical characteristics and application methods.

Some common forms include:

  • Hot Melt Sticks or Glue Sticks
  • Hot Melt Pellets or Granules
  • Hot Melt Powders
  • Hot Melt Cartridges
  • Hot Melt Films, Sheets, or thermoplastic films.

For Hot Melt Films, they can be extruded in different structures, like Film, Web, and Net. In this article, we will dive into the subject of hot melt adhesives focusing on their extrusion in a net structure, which we call thermoplastic or Hot Melt Net. This is an important innovation to make adhesive more flexible and breathable. We’ll learn more about its unique form, applications, functions, and the numerous advantages and added value adhesive net offers over traditional gluing methods.

The Benefits and Applications of Bio-Based Hot Melt Adhesives

 

As businesses aim for more environmentally friendly adhesive options, bio-based hot melt adhesives have become a good choice compared to traditional adhesives. In this article, we will explore what bio-based hot melt adhesives are, how they are made, and the advantages and uses they offer. By understanding this innovative adhesive technology, companies can make informed choices to minimize their impact on the environment and support sustainable practices.

Standards are extremely stringent in the construction industry. It is directly related to the will of governments to improve energy efficiency  and soundproofing of households. Efforts are made to make sure homes meet the requirements of both residents and governments in terms of the use of energy ressources.

When constructing building or when setting up a room, thermal and sound insulation system is an important choice that will have an impact on the quality of life and comfort of the inhabitants.

Insulation devices play a significant role in ensuring that homes comply with regulations that tend to conserve energy and protect citizens’ well-being and safety.
