The institute believes it can be competitive in manufacturing, processing and offer the properties needed for market-leading polystyrene insulation boards.
Further adding since OrganoPor also offers a competitive price, it has an opportunity to conquer the market. Fraunhofer LBF will present more about the new insulating material at the JEC World Trade Fair in Paris, from March 3 to 5, 2020, in Hall 6, Booth J 28 of the Fraunhofer-Gesellschaft.
Polystyrene foam boards (PS) are the most common insulation material, used in more than 90% of all thermal insulation composite systems (TICS). There have been hardly any bio-based alternatives, as they are associated with manageability and price issues.
These use residual and waste materials such as cork and corncobs, waterborne resins based on lignin, and mineral fillers as flame retardants. To manufacture the panels, the porous particles of renewable raw materials are coated with a bio-based duromer, that includes a mineral flame retardant, and are then pressed.
The resulting boards behave in fires in the same way as the latest-generation polystyrene foam hybrid materials. Component densities of 120 kg/m³ and thermal conductivities of 40 mW/m K have been achieved. Its open-pored structure provides control of water vapor diffusion. Applications tests performed by DAW, its industrial partner, have shown that OrganoPor can be easily used in TICSs.
OrganoPor is particularly economical to produce, due to the structural and processing parallels to polystyrene foam hybrid materials. An additional benefit is the availability of raw materials. OrganoPor has a great opportunity to establish itself as an ecological alternative in the insulation material market.
Plastics Recycling – Advantages and Disadvantages
The German Federal Ministry of Food and Agriculture (BMEL) supported the “Insulation Materials for Building Insulation from Biogenic Residues with Spherical, Porous Structure and Fire-Retardant Bioresin Matrices” project via the Agency for Renewable Raw Materials (FNR). Project partners included JOMA Dämmstoffwerk GmbH, J. Rettenmaier & Söhne GmbH + Co KG, Nabaltec and DAW SE (Deutsche Amphibolin-Werke).
