Definitions
- the invention relates to a foaming device for foaming an expandable particle foam material.
- Polymer foams in particular made of polystyrene (PS), erythropoietic protoporphyria (EPP) or expanded thermoplastic polyurethane (eTPU) are driven in a multi-stage process from the starting product, a polystyrene granulate or polystyrene beads, to the finished foam part, e.g - Molded parts or transport packaging, especially in vehicles, processed for structural reinforcement, noise insulation, or weight reduction.
- the propellant-loaded granules are pre-foamed with an increase in volume to form foam beads or the foam intermediate product, with this foam intermediate product having a very significant impact on the mechanical and thermal properties of the end product.
- a polymer foam in particular a polystyrene particle foam, is currently the most important material for the thermal insulation of old and new buildings.
- thermal insulation layer or the thermal conductivity of the insulating material is reduced.
- Mechanical strength is also important for practical use, and it is known that increased strength is associated with increased use of the starting material. However, a larger amount of the starting material worsens the thermal insulation properties, so that a compromise has to be found here.
- the thermal conductivity can be reduced by increasing the cell/wall thickness ratio. This makes it possible to vary the thermal conductivity in a quasi-decoupled manner from the mechanical properties.
