Heat lamination is a process for producing multi-layer products (these are called laminates), which allows the properties of the layers to be combined. It can be understood as ‘welding’ the layers to each other.
It uses only heat and some pressure to bond the two surfaces together, it means that no additional material like adhesive is necessary. This is only possible if the two materials are „a bit similar” to each other chemically. If the material is too sensitive to heat (for example non-crosslinked PE foam), it can’t be processed this way.
Materials that can be laminated to our foam with heat lamination:
- Other cross-linked polyolefin foams
- LDPE, HDPE, PP films
- EVA films, certain other ethylene copolymer films
- Certain PU foams
- Certain textiles
- Certain papers
Lamination can be stimulated in our laboratory and the new materials can be tested, so if you have something in mind that is not on the list, it can be tested and feedback or recommendation for alternatives can gave.
Heat lamination can be a continuous process, but a batch process too. For the continuous process around 20 mm is the maximum thickness that is possible. With the batch process it is possible to laminate lots and lots of layers on each other, so for example, foam blocks with up to 500 mm thickness can be produced.
