AREAS OF APPLICATION
Outstanding water resistance: an outstanding property that allows for diverse application opportunities.
- Separation walls in wet and damp room areas
- Insert or rimmed edge for wet and damp room doors
- Windowsill connection profiles
- Sub-roof + wallboards
- Carrier boards for plaster, tile, and gypsum
- Tile and kitchen counters
Low thermal conductivity, high pressure resistance, and breathability: properties that create new perspectives.
- Decoupling plate for the construction and automotive sectors (avoidance of cold gap)
- Thermal bridge-free installation of windows and balcony doors (according to DIN4108 – Supplement 2)
- Secure connection of insulation to concrete upstands
- Sub-roof + wallboards (for example, construction of waterproof sub-roof)
- Friction-locked and secure installation of outdoor lighting, roller shade boxes, canopies, etc.
MANUFACTURING PROCESS
To produce Kerdyn® Green FR, PET granulate from the recycling process (drink bottles) is molten in an extruder and mixed with various additives and a propellant. This material is then extruded in an endless cord made up of many small “strings”.
After the extrusion tool, the strings unite into a raw board.
After a cooling period, the raw board is cut to a length of approx. 1300 mm and formatted quadrilaterally.
The thickness of the board is thereby reduced to approx. 45 mm.
In the next process, the raw boards undergo heating and are then welded into a block layer by layer.
After reaching its maximum size, the block is formatted six-sidedly to the size of 1005 x 1250 x 2400 mm.
The required boards are cut from this block.
This sophisticated process is selected to transfer the high mechanical properties parallel to the direction of extrusion into the board surface.
