With its advantages of high strength, light weight and high production efficiency, polyurethane composite materials can not only meet the performance requirements of many industrial applications, but also improve the service life of products, reduce carbon emissions and waste generation, Contributing to sustainable development and circular economy. As the inventor of polyurethane, material manufacturer Covestro has been committed to promoting the innovation and development of polyurethane composite material applications.
During the 2023 Shenzhen International Composites Industry Technology Exhibition, which will be held from March 23 to 25, Covestro will be at the Shenzhen Convention and Exhibition Center, Hall 2, 1201
At the booth, it displayed a series of polyurethane composite application solutions jointly developed with partners, including pultruded profiles for window frames and photovoltaic frames, fan blades, upper shells of new energy battery packs, power distribution poles and building exteriors. Facade insulation support. These products involve composite material production processes such as pultrusion, high pressure resin transfer molding (HP-RTM), vacuum infusion and filament winding. The main exhibits include:
Baiduo® polyurethane pultrusion window frame has excellent thermal insulation performance and good mechanical properties, which can reduce building energy consumption. The profile is made of glass-fiber reinforced polyurethane composite material and is finished with a water-based polyurethane coating. and conventional aluminum alloys or
Compared with PVC door and window profiles, it has better thermal insulation performance, so it has lower carbon emissions and is more environmentally friendly.
Baiduo® Polyurethane Pultrusion Photovoltaic Frame is made of polyurethane pultrusion composite material and coated with water-based polyurethane coating. It has good corrosion resistance, especially suitable for areas with high humidity and high salt spray, and its mechanical properties are also excellent. As a non-metallic frame, BYDO® polyurethane pultruded photovoltaic frame does not need to be grounded, and it also helps to improve the power generation efficiency of solar panels. Regardless of whether it is applied to a photovoltaic power station or a photovoltaic building-integrated system, the comprehensive cost of this innovative solution is better than that of an aluminum alloy frame. Baiduo®HP-RTM
Process polyurethane composite materialBattery pack upper shell is an important application of polyurethane in the field of new energy vehicles. Polyurethane composite material is lightweight and the shell thickness can be as low as
0.8 mm, reduce the total greenhouse gas emissions by reducing the weight of the power battery, and has good flame retardant properties. In addition, HP-RTM
The process adopts the “one-to-two” design of one glue injection machine and two presses, which can significantly improve production efficiency and reduce production costs.
In addition, use Baiduo® and
Distribution poles and communication poles made of Desmocomp® polyurethane materials can meet the requirements of different regions, environments or terrains. Compared with traditional concrete poles, the solution is only one-eighth the weight of concrete poles, can be transported and installed more efficiently even in complex terrain areas, and can significantly reduce carbon dioxide generated during manufacturing and transportation emission. In addition, its unique design structure can withstand the test of extreme conditions such as typhoons, thunderstorms and corrosive environments, and its service life can be as long as
For more than 40 years, the maintenance cost of the whole life cycle will be significantly reduced.
Covestro can also offer specifications with alternative raw materials for various polyurethane solutions, e.g. through ISCCPLUS
Mass balance-certified low-carbon footprint polyurethane and some bio-based raw materials help downstream companies transition to a circular economy.
