Klebelösungen aller Arten, darunter auch thermoplastische Klebstoffe, sind heute aus der Automobilindustrie nicht mehr wegzudenken. Gerade im Bereich des Fahrzeuginnenraums oder der Innenverkleidung kommen sogenannte Hotmelt Adhesives in Form von Klebefolien, Klebewebs oder verschiedenen Netzstrukturen häufig zum Einsatz und helfen, die Verklebung von einzelnen Materialien und die Verarbeitungsschritte zu vereinfachen.

Thermoplastic-adhesive-Automotive-door-panel-molding-processFür die automobile Anwendung müssen Hotmelt Klebstoffe verschiedenste technische, mechanische und physikalische Anforderungen erfüllen, darunter beispielsweise Beständigkeit gegen Verschleiß, Chemikalien oder Temperaturschwankungen. Darüber hinaus werden intelligente Klebelösungen auch für die Kaschierung von Textilien, Schäumen, Leder, Kunstleder oder anderen Materialien für die Fahrzeuginnenausstattung verwendet. Diese Verbundteile werden dann in Autositzen, Kopfstützen, Armlehnen, Türverkleidungen oder dem Dachhimmel eingesetzt. Klebevliese und Klebebänder werden zusätzlich auch bei der thermischen Dämmung, Schalldämmung oder der Isolation als Klebemittel zwischen den verschiedenen Dämmmaterialien verwendet.



It’s really easy to bond it, in 2 steps only!


Why you should use hotmelt adhesive tape for hemming ?

  • To replace the sewing process
  • To make the process easier
  • To reinforce the finishing, and upgrade the quality


Step 1 : Preparation


  • Make sure your fabric / garment is pre-washed to avoid the narrowing of the hem.
  • Cut the length of hotmelt adhesive tape you need.


What is a headliner?

Headliners are made of composite fabrics, a combination of different materials with different functionalities. The composite parts are adhered to the roof of the car and help to improve the interior appeal as well as provide an element of insulation against heat and noise.

A typical headliner consists of multiple layers: a face side, a rigid core in the center, and a backing. The different layers consist of a multitude of materials such as knit or non-woven fabric, rigid foam, reinforcement material, etc. Liquid and dry adhesives (film, web, net) are then used to bond the different layers together in order to enhance the headliner’s unique shape and contours.

Functions of headliners

The multi-layered headliners bring together various functionalities:

  • better look and comfort through soft touch
  • stiffness of the roof
  • absorption of excess noise from the outside
  • insulation against heat and cold, regulation of internal temperature
  • improved acoustics for audio systems

Special requirements for headliner lamination

Compared to other interior parts of the car, headliners are much more likely to deviate from their original position due to their weight. The headliner can delaminate and eventually fall off after a period of poor handling or lack of care. This not only leads to a degradation of aesthetic value and comfort but also to declined safety and insulation of the car.

To ensure the headliner’s durability, the right choice of adhesive is very important. Heat, humidity, and time can significantly degrade the bonding strength of the adhesive and the different layers become less resistant and brittle.

Notably hot melt adhesives for dry lamination offer a good and clean alternative compared to liquid adhesives. Between the different layers, the Thermo adhesive can serve as barrier film and bonding, especially in the wet process, and they can be directly applied in the dry process for both the face and core sides.

Hot melt adhesives not only provide an efficient bonding and backing, but also an eco-friendly, sustainable and low VOC solution for headlining.

Hotmelt adhesive is also called thermoadhesive or thermoplastic adhesive. It can be manufactured and produced in different forms, such as granule, powder, stick, web, film, net on a roll.

Thermoplastic hot melt adhesive on a roll can combine various materials, like foam, textile, and leather, aluminum, which can be applied in automotive, garment, shoes, leather, and cosmetic and filtration applications with a clean lamination process.


Hotmelt adhesive web is also called thermoadhesive Web. It is used to bond and laminate with different materials, such as textile, leather, foam, 3D spacer, aluminum sheet. Its unique characters (soft, breathable, light weight) makes it the most versatile adhesive in various applications.


Hotmelt adheshive Web is made of 100% thermoplastic polymer resins. The final form is in roll with different width and weight. The fabric structure are like nonwoven. It can be activated with heat, like flatbed lamination machine, hot roller, hot press, heated air etc. For bonding process, it is more clean and easier to handle comparing to hotmelt powder.
