The central issue in all polyurethane applications is the conversion from the past linear economy into a circular economy, and the use of sustainable raw materials in manufacturing. To do so, manufacturers are taking measures such as using bio-based raw materials, chemical recycling, and CO2 as a synthesis component. Digitalization, electromobility, autonomous driving and the construction industry are also driving PU development.

Sustainable Growth

Styrenics can be polymerized using different technologies and it can be modified with a range of copolymers. The resulting plastics offer a wide range of properties allowing to customize them for different applications. Because of this range of properties they are suitable for many industries. Strong demand is for example driven by the automotive industry, healthcare and the packaging industry.

Optics play an increasingly important role in plastic components. Glossy and even surfaces are decisive for an attractive appearance. With glass fiber-reinforced polyamides (PA), these requirements can usually only be achieved with an additional coating. A PA specially developed for surface design offers an alternative approach.

Renouncement is the trend that determines public perception of plastics today. Many consumers prefer products that are better for the environment, which is often equated to using less plastics. It is true, though, that plastics are important materials when it comes to finding answers to the challenges posed by the increase in population, high energy demand as well as growing urbanization and mobility.

“Unfortunately, the Only Globally Accepted Ideology Is Money”

Bio-based plastics can lock away vast quantities of CO2 in durable, recyclable applications and make a real contribution to climate protection. All that is needed for this is the right product design and a functioning circular economy. By focusing more on this approach, the plastics sector has the chance to evolve into a key industry of a green economy.

For lightweight applications e. g. in automotive engineering BASF developed carbon fiber-reinforced polyphthalamide (PPA) grades with fillings of 20, 30 und 40 %.

BASF is now expanding its polyphthalamide (PPA) portfolio of Ultramid Advanced with carbon-fiber reinforced grades with fillings of 20, 30 and 40 % . They make for extremely lightweight parts, can safely replace aluminum and magnesium without loss in stiffness and strength and are electrically conductive.

The new grades show high dimensional stability due to low water uptake, excellent chemical and hydrolysis resistance, high strength and modulus. The new carbon fiber (CF)-reinforced grades can be used to manufacture automotive structural parts for body, chassis and powertrain, for pumps, fans, gears and compressors in industrial applications as well as for stable and ultra-lightweight components in consumer electronics.

The mechanical performance of the new carbon fiber-reinforced PPA grades can be tuned by the choice and the content of the carbon fiber as well as by the additive technology. Ultramid Advanced N3HC8 with 40 % carbon fiber filling shows a better strength and modulus at 80 °C (conditioned) than magnesium or aluminum. “Our new PPA compounds with carbon fibers are the ideal metal replacement”, says Michael Pilarski from PPA business management at BASF. “And this not only from a material property point of view. Lately, we have seen safety issues at magnesium producers in different countries, which makes the supply rather unpredictable. Producing parts out of magnesium or aluminum also requires additional post-processing and tooling which increases system costs. Given the opportunities for 25 to 30 % weight reduction with our new PPA grades, we can offer a safe, cost-efficient and high-performance alternative for parts traditionally manufactured from metal.”

The materials reportedly can contribute to functional integration and weight reduction in different industries: the range of cars with e-drive or fuel cell engines can be increased by weight reduction of structural or powertrain parts; lightweight, thin precision structures in consumer electronics benefit from the high stiffness and strength, the excellent dimensional stability as well as the extremely low weight and the good processability of the new PPA materials; heavy, highly loaded and long-lasting industrial equipment like pumps and compressors can be easily produced because of the good dimensional stability as well as the high chemical, heat and abrasion resistance of the new CF grades.

The carbon fiber-reinforced PPA compounds also show a lower weight and higher tensile modulus than glass fiber-reinforced polyamides (PA) with similar reinforcements. PPA grades reinforced with 20 wt. % carbon fibers are about 20 wt. % lighter than PA6 or PA66 filled with 50 % glass fibers. According to the company, the tensile strength of a 20 % carbon fiber-reinforced Ultramid Advanced compound is either better or equivalent to a glass fiber-reinforced polyamide filled with 50 % while showing better processability.
