Innovative WPC Facade Elements
This work focused on the influence of formulation components and processing parameters on impact strength and weather resistance. Additionally, we examined the optimization of the extrusion technology for the production of WPC facades by the example of window profiles.
Impact strength was optimized through using various impact modifiers in the PVC matrix. Another priority was the selection of suitable PVC types and lubricant systems. The optimization of weather resistance was limited to the reduction of water absorption and fungal infestation. Some formulations, especially those with chemically modified wood particles, showed a significant reduction of water absorption. A resistance to wood-destroying fungi was observed with all formulations. During the project a suitable extrusion die with an innovative window profile geometry was developed.
The project was a cooperation between SKZ and the Institute for Wood Biology and Wood Technology of Göttingen University.
