2. Contact allergens in p-tert-butylphenol-formaldehyde resin
Sammanfattning : p-tert-Butylphenol-formaldehyde resin (PTBP-F-R) is used as a binder in many adhesive formulations and it consists of a complex mixture of substances, most of which are unknown. The resin has been reported to cause allergic contact dermatitis since the 1950s. LÄS MER
3. Physical, Chemical and Biochemical Modifications of Industrial Softwood Kraft Lignin for Different Applications
Sammanfattning : Various technical lignins, e.g. industrial Softwood Kraft lignin (SKL), are now largely available while they are generally underutilized due to their heterogeneous and complicated structures and/or the poor properties. LÄS MER
4. Combination of heating and preservative impregnation of wood for outdoor exposure
Sammanfattning : The research is presented as a composite thesis containing a theoretical explanatory review based on four scientific articles. The thesis covers the investigation of wood modification methods, which in the future could possibly be developed further to enhance the performance of wood products in an efficient and economical way.

5. Wood fiber composites : processing, structure and properties
Sammanfattning : The goal of this work has been to investigate how to make wood polymer composite materials with good mechanical properties, which also could be tailored for different applications. The fundamental idea behind the work was that good mechanical properties of the composite material require that the stiffness and strength of the wood cell wall material are really utilized. LÄS MER
