    Shows excellent adhesion to a diverse range of substrates. Certain types of PA demonstrate superior bonding performances, especially on challenging substrates like treated textiles, metal, and leather. Most CoPA variants can be activated by steam. One of the main characteristic is the high resistance to washing (up to 90°C) and stonewash, chemical cleaning, steam,post-dyeing, and chemical aggression such as fuel and solvents. Some variants exhibit high heat resistance.

    Remarkable for their resilience against washing and hydrolysis, most COPEs boast good resistance to plasticizers. Therefore, it is widely used for PVC lamination. They can offer enhanced softness and flexibility compared to Pa variants. Additionally, COPEs are resistant to steam and generally exhibit limited resistance to chemicals and dry-cleaning processes.

    Great for bonding most substrates and bringing good economic advantages. Works well for PU and EVA foam but also non-treated fabrics. As PO is a versatile polymer, it can be used for simple spun-bond lamination but also for challenging high-temperature molding of the industry. If wash resistance is required, it is preferable to use other polymers.

    Typical characteristics include excellent resistance to abrasion, elasticity (elongation before breaking), and exceptional flexibility. Some grades can be activated at low temperatures, this offers great opportunities when working with heat-sensitive materials. When a soft hand feel is required, it will be the go-to polymer.

  • Structure



    Thermoadhesive films have a wide range of uses, from textiles to aluminum foil or PVC to PU foam. They can do more than just bond – they can seal, stiffen, or waterproof. These films are perfect for bonding large flat surfaces efficiently, whether continuously or in batches. Additionally, slit adhesive films provide textiles with flexibility and a soft touch while ensuring reliable processing, along with benefits like improved sound insulation and bubble-free lamination.


    Web thermoadhesives can be used with a wide range of polymers with different fusing temperatures and viscosities. These polymers are available in exceptionally lightweight variants, enhancing softness and facilitating composite construction. Their open structure prevents air encapsulation and can offer breathability. With easy handling and stability during unrolling, they are conducive to seamless processing. Their mouldable and stretchable nature, coupled with effortless energy transfer, ensures versatility in applications.


    Designed to accommodate a range of assembly needs, these adhesives are well-suited for bonding flexible, semi-rigid, porous, or absorbent substrates. They offer versatility for diverse applications. Characterized by regular and uniform structures, they ensure consistent performance. The structure brings can bring higher bonding performance compared to other forms. Additionally, depending on the specific structure, they provide increased flexibility and breathability, catering to a wide array of requirements.


    The powder is loaded into a specialized container, either manually or via an automatic mechanism (such as a screw or cyclone system). It is then evenly dispersed onto the substrate by a needle roller equipped with an oscillating brush. This powder is activated by exposure to an IR field, using either an oven or a heater. Subsequently, a second substrate is introduced into the system via the top pressure roller of a calendar, where it is pressed against the first substrate coated with the activated powder adhesive. Alternatively, this powder scattering process can be integrated with a flatbed laminator for enhanced lamination quality.




    Thermoadhesives offer a cutting-edge solution that empowers footwear manufacturers to lead with sustainability and outperform in cost-efficiency.
