Biobased Impregnation Resins for High Pressure Laminates
SUPERVISOR: Antje POTTHAST
PROJECT ASSIGNED TO: Elisabeth BILLICH
High-pressure laminates (HPL) are engineered materials that are used as both interior and exterior decorative horizontal and vertical surfaces that require demanding properties in terms of high wear, abrasion and stain resistance. They can be employed for a wide range of applications, including the construction of furniture and countertops, but also for wall cladding, facades and balconies. HPL consist of various layers comprising a core layer of several sheets of Kraft paper, a top layer of decorative paper. The paper is impregnated with low viscous resins. For the core layer, phenol-formaldehyde (PF) resins are commonly used. This process renders the final product resistant to chemicals, moisture and heat, and imparts excellent mechanical properties. However, the two main constituents of PF resins are derived from fossil raw materials. Environmental and climate protection are becoming increasingly important. Many industries, including the laminate industry, are therefore striving to integrate more sustainable resources into their production processes. With these considerations in mind, the aim of this project is to find an alternative to conventional PF resins. A bio-based impregnation resin is to be developed, consisting mainly of renewable raw materials and non-hazardous chemicals, aiming at protecting the environment.
