SABIC's copolymers for aerospace industry

For smoke density according to ASTM E662, the materials performed extremely well at low rates such as Ds 58 (at 3mm) and Ds 68 (at 2mm) according to independent lab testing. Compared to competitive materials such as polyvinyl chloride/polymethyl methacrylate (PVC/PMMA), which can experience compliance issues, the SABIC grades meet tough commercial toxicity standards from Airbus and Boeing.

These non-brominated, non-chlorinated, non-phosphate and non-halogenated flame-retardant SABIC materials also comply with major environmental protocols such as the European Union (EU) Directive on Restriction of Hazardous Substances (RoHS) and TCO99 International, supporting environmental responsibility.

An important advantage of these new grades is their ability to be used for both extrusion and injection molding applications. Typically, customers would require two different products with different flow behaviors for extrusion and injection molding. LEXAN CFR5630 and CFR5630D grades have a special feature called the shear-thinning effect. It allows the product to flow slowly in low shear conditions, such as the extrusion process, and to flow quickly in high-shear processes, such as injection molding. This versatility will enable customers to avoid the effort and time required to certify two different products; instead they can use the same SABIC material for two different processes.

LEXAN CFR5630D copolymer for LED lighting offers wide-angle light scattering for excellent aesthetics combined with optimal light transmission. This material can be used for a range of aircraft lighting applications. It is ultraviolet (UV)-stabilized for improved color stability over the lifetime of the part. We offer it in five pre-selected diffusive colors.

LEXAN CFR5630 copolymer is available as transparent and in multiple colors.
