ide (PEI), elevates the performance of tapes by supplying inherent flame retardance, long-term heat stability, outstanding strength and stiffness, and dimensional stability. “Our collaboration with SABIC has enabled us to
expand our portfolio from materials for computer electronics into the higher-performance compos- ites space where we are able to meet the most stringent demands of aerospace applications,” says Xu Shenggang, Chief Technology Officer, Jiangsu Hansu. “Selecting Ultem 1000F3SP powder allows us to offer an alternative to traditional epoxies widely used in the industry. It provides an excep- tional balance of properties, while providing more-efficient processing than thermosets, since curing is not needed.”
During the manufacturing process, Jiangsu Hansu combines continuous carbon fibres with Ultem 1000F3SP powder, a product offering Restriction of Hazardous Substances (RoHS) compliance and a glass transition temperature
) of 217˚C. The easy dispersion of Ultem 1000F3SP powder in water makes it possible to create a homogeneous slurry that is uniformly distributed among the carbon fibres. The resulting composite tape has highly consistent properties, which are critical for demanding aero- space applications. SABIC also produces Ultem resin in injection moulding grades. Injection moulded components can then be thermo- formed with UD composite tape and overmoulded with functional elements, all with the same polymer. The advantages of this ap- proach include the potential for recyclability and a high level of design flexibility. PEI is one of the highest-performing thermoplastics in commercial production. It is an amorphous polymer with a high Tg
(Tg (around 70°C higher than PEEK) and provides
excellent impact resistance. It also provides outstanding flame, smoke and toxicity (FST) performance, as confirmed in standard Ohio State University tests.
