| Résumé : |
Foamed polystyrene in window profiles and façade elements can improve their thermal insulation and there-fore their environmental efficiency. Simultaneous extrusion of polyvinyl chloride profiles with a PS foam core is challenging due to the different processing conditions and has not been performed before. A trial plant for researching this process has now been set up at the SKZ. |
| Note de contenu : |
- One-step process for foam-filled profiles
- Homogeneous and fine-celled foam structure
- Processing in a tandem extrusion line
- Problems with the die
- Welding of foam-filled profiles
- How sustainable is the process ?
- Environmental life-cycle analysis
- Fig. 1 : The foaming of PS was investigated in a test system developed for this purpose
- Fig. 2 : SEM micrograph of a foam sample with graphite as nucleation agent with 150x magnification : the closed-cell, highly homogeneous and fine-celled structure of the foams is good to see
- Fig. 3 : The tandem extrusion system permits extrusion of PVC profiles with foamed PS core
- Fig. 4 : Front view of the extrusion die with frame radiator : the mold combines PVC profile extrusion with PS foam extrusion
- Fig. 5 : Simulated pressure and viscosity profiles for the PVC flow channel of the die and the PS flow channel
- Fig. 6 : Specific energy consumption of the individual components based on 1m of manufac-tured profile |
