Self-Healing Bio-Based Adhesive System for Circular Bonding Applications
This technology is a formaldehyde-free, bio-based adhesive for wood and similar materials that can self-heal damage by heating and cooling, using reversible Diels-Alder chemistry for easy repair, recycling, and sustainable industrial use.
Biobased adhesive formulation
Biobased adhesive formulation A novel production method for a biobased adhesive, which comprises a tailored lignin structure as main component, is presented. The process technology overcomes the use of toxic phenol and formaldehyde, while the resulting adhesive exhibits superior physicochemical and mechanical properties. Challenge Phenol-formaldehyde resins are renowned representatives for the bonding of various materials […]
Process for production of metal-wood composite profiles
Process for production of metal-wood composite profiles The process technology enables the production of high-performance metal-wood composite profiles by integrating wood core sheathing and specifically modified wood core materials into a single, energy-efficient manufacturing operation. Challenge Composite structures combine properties of individual materials to provide advantageous property profiles, versatile performance in application and economic advantages […]
Production of plates and mouldings from popcorn granules
Production of plates and mouldings from popcorn granules Newly developed processes for the production of popcorn granulate boards and mouldings. They now make it possible to produce boards or mouldings from renewable resources with improved water resistance and flexural strength. The boards and mouldings are particularly suitable for packaging, furniture, automotive (including caravans) and housing […]
Binder based on oil plant esters for the production of wood and composite materials
By far the most commonly used binders for the production of wood-based composites are the so-called urea-formaldehyde (UF) resins. However, these are susceptible to hydrolysis and therefore the produced wood-based materials still emit formaldehyde even years after their production. Scientists at the University of Göttingen, Germany developed a biological binder based on oil plant residues for the production of composite materials. The new formaldehyde-free binder has excellent properties and could therefore replace existing binders in many applications.
Increasing the reactivity of Isocyanate binders
Increasing the reactivity of Isocyanate binders An improved process for the production of wood-based panels based on isocyanate binders / adhesives (PMDI) was developed at the University of Göttingen. The times and costs for production of wood-based materials (e.g. chipboard, fiberboards (MDF, HDF), OSB etc.) can be reduced without neccessity to change hardware in existing […]
