- Flame-free lamination of interior trim
- A “cool“ production method, high process stability
- Short cycle time, excellent green strength
- Complies with GMW 14892 standard
A “cool” production method for all laminators of PP – of course flame-free!
The lightweight polypropylene door panels of the new Chevrolet Malibu are laminated without pre-treatment. Jowatherm-Reaktant® polyolefin hot melt (POR) is now used by NYX in a process called “in mold graining” (IMG). Injection moulded parts of polypropylene, laminated with a TPO skin, and using a reactive polyolefin-based Jowatherm-Reaktant® hot melt adhesive – make a perfect team with an added feature: fully recyclable without prior separation.
Short cycle times, outstanding green strength, which is stronger than the skin, and GMW 14892 approved final performance, complete the package. Visually attractive high quality soft trim, reduced weight, and of course maximum cost efficiency, are the driving forces behind new developments for decorative interiors of today’s vehicles. The key material is polypropylene (PP), a light weight and low cost product with the potential for easy recycling. Together with a state-of-the-art FRIMO IMG lamination line using TPO foam skin, NYX has established a new benchmark in the market for high quality soft trim interiors.
However, the low surface energy of polypropylene is not suitable for bonding with standard adhesives. While corona treatment and priming of TPO and PP foam cover stock is a standard and cost-efficient method, the surface treatment of 3D injection moulded PP is still a challenge. Solutions like low-pressure plasma treatment or fluorination are time-consuming and very expensive. This still makes flame treatment the common choice, even considering the risk of fire, and potential quality aspects. The new reactive polyolefin hot melt (POR) of the Jowatherm-Reaktant® series opens up completely new possibilities without the concerns mentioned above. The special polyolefin-based adhesives do not contain hazardous components like monomeric isocyanate and can easily be coated on the substrates.

Consistency and standardisation. These objectives of the modular production system used by numerous manufacturers in the automotive industry are linked to the entire supply chain, including the processed materials and adhesives. Adhesives for 3D laminating interior car parts have to provide superior performance independent of the application method and the laminating technology. Whether applied by roller, nozzle or spraying, laminated with a press or by vacuum deep-drawing – the same adhesive should be used in all processes and fulfil the different requirements.
Jowatherm-Reaktant® 642.00/08 has been developed to meet all demands with only one adhesive.

Jowapur®dispersions are mainly used for the lamination of interior parts of vehicles (such as instrument panels, door and column panelling, and headlining) with decorative thermoplastic foils (e.g. PVC, PU or polyolefin), textile foam and woven composites, and real leather in vacuum deepdrawing and stamping methods. The newly developed PU dispersion Jowapur® 158.97 is used in combination with the new crosslinking agent Jowat® 197.65 for real leather and thermoplastic foil lamination of all kind.

Thermoplastic PO hot melts are used to a steadily increasing degree in flat lamination for car interiors. One of the greatest benefits provided by thermoplastic hot melts is the block-free, storage stable precoating of reel material. The new thermoplastic PO hot melt adhesive Jowat-Toptherm® 238.20 is characterised by a long open time, high initial strength and good adhesion to materials based on PP (e.g. NF-PP).

The continuously growing diversity of new matrix material combinations like NF-PP is highly challenging in bonding, especially on surfaces with low surface tension. With the new Jowat-Toptherm® 238.80, Jowat succeeded in developing a thermoplastic PO hot melt adhesive that is characterised by an extremely high heat resistance and a very wide range of adhesion to materials like PP and NFPP.
