Thermoset: Versatile and highly efficient PU-based composites
Thermoset composites are built up by polyurethane resin as a matrix in combination with selected reinforcement materials such as short, long or continuous fibers as well as mats. These fiber-reinforced composites can be produced via pultrusion, infusion, or resin transfer molding processes.
Thanks to excellent properties and customizable solutions, polyurethane (PU) resin systems offer exciting possibilities in new applications and markets including automotive, construction and wind. As a matrix material, PU has excellent properties that provide advantages in both processing and product quality.
PU materials demonstrate very high reactivity and tunable processing viscosity and enable the construction of customized properties. The resin effectively impregnates the glass fibers, forming a composite that is both durable and lightweight, with high stability and stiffness.
Nevertheless, numerous outdoor applications still make use of aluminum, steel, wood, or concrete instead of high-tech composite solutions. Industries are looking for suitable lightweight outdoor solutions with reliable long-term UV- and weathering resistance.
We develop advanced PU systems for thermoset composites across a variety of industries. PU-based fiber-reinforced plastics can be processed using pultrusion, infusion, or resin transfer molding processes, depending on the requirements of a given application.
Pultrusion: Tunable PU resins for high-performance profiles
We offer two dedicated PU systems for pultrusion: our Baydur® PUL system as well as our Desmocomp is produced by a pultrusion process. The Baydur® PUL system is now well established in the cost-effective production of window and door profiles that surpass aluminum in terms of thermal insulation, mechanical stability and noise insulation. Our aliphatic Desmocomp® PU resin matrix system offers excellent UV- , weathering, and flame resistance . Desmocomp® is designed for outdoor applications and exposure to environmental influences, such as sunlight or salty climates. It combines with excellent mechanical properties and eliminates the need for UV stabilizers or protective coatings.
Infusion: High-strength, efficient PU resins for long-lasting components
Resin transfer molding: Quick, effective processing with a lower environmental footprint
Because of its rapid crosslinking behavior, our 2K polyurethane system Baypreg® has become an established matrix material for lightweight automotive constructions such as loading floors in trunks, hat racks, headliners and wheel covers. It provides effective bonding and three times the energy absorption potential of comparable resins, for an extremely high level of occupant safety in the event of a collision. Further advantages include low emissions, thermal and acoustic insulation through a PUR core layer, flexible surface design options, and excellent surface quality.
