AKULON ULTRAFLOW USED IN NEW GENERATION OF VACUUM CLEANER E-MOTORS
10 December 2003 - DSM Engineering Plastics

Bosch und Siemens-Hausgeräte has selected Akulon Ultraflow for key parts of the E-Motors in their new generation vacuum cleaners. Akulon Ultraflow was recently introduced by DSM Engineering Plastics.

Europe’s domestic appliance manufacturer Bosch und Siemens-Hausgeräte is to use Akulon Ultraflow in the E-Motors of their new generation vacuum cleaners.

The high flow characteristics of Akulon Ultraflow allow for increased productivity and greater design freedom, making it the perfect product for use in the brushholder housings and end-laminates of the UL/EN-approved vacuum cleaner motors.

Facing the requirements of the new white-goods standard (EN60335-1), Bosch und Siemens-Hausgeräte selected the UL certified flame-retardant Akulon Ultraflow K-FKGS6 (PA6 GF/FR) for this application. The material is able to meet the increased demands for resistance to heat, fire and tracking. Akulon Ultraflow K-FKGS6 complies with the Glow-Wire-Ignition-Test up to 800C at 1.0 mm and is flame-retarded according to UL94 class V-0 at 0.75 mm.

Akulon Ultraflow, which is manufactured by DSM Engineering Plastics, was launched recently and is already proving to be successful. Its exceptional flow properties make Akulon Ultraflow K-FKGS6 the best choice for use in parts with thin wall thickness and long flow-paths. Moreover, the high flow reduces injection moulding cycle times, thus significantly increasing productivity in comparison with a standard PA6 GF30.

Other key advantages include high quality appearance, extended tool life and the ability to use smaller injection moulding machines, reducing overall capital investment.

Akulon Ultraflow PA6 is based on DSM proprietary technology. It provides up to 80% greater flow and up to 25%-40% cycle time reduction in injection moulding when compared to standard PA6 grades, with no significant loss of mechanical properties.

Thin-wall items with long flow paths and high-appearance benefit especially from Akulon Ultraflow owing to better surface quality and lower moulded-in warpage and other internal stresses.

Typical applications include under-bonnet automotive components and assemblies including air cleaners, intake manifolds and engine covers; automotive appearance items such as door handles and mirror brackets; electrical components such as connectors, junction boxes, and terminal blocks; power tool and lawn and garden enclosures and housings; a wide variety of sports equipment, including ski bindings, and inline skates; and a broad range of appliance and building and construction applications.

About: DSM Engineering Plastics
DSM Engineering Plastics is a business group forming part of DSM's Performance Materials cluster. DSM EP is a global supplier of Stanyl PA46 and Akulon 6 and 66 polyamides, Arnitel TPE-E, Arnite PBT and PET polyesters, Xantar polycarbonate, Yparex extrudable adhesive resins, and Stamylan UH Ultra High Molecular Weight PE. These materials are used in technical components for electrical appliances, electronic equipment and cars, in barrier packaging films as well as in many mechanical and extrusion applications. The business group had annual sales of EUR 566 million in 2003. With Stanyl, it is the global market leader in high heat polyamides.

Stanyl is a family of heat-resistant polyamides from DSM Engineering Plastics. Stanyl’s high crystallinity (70% versus 50% for conventional PA66) results in high heat distortion temperatures of 190C for unreinforced grades, up to 290C for reinforced. Stanyl grades are used in automotive clutch plates, charge air coolers, chain tensioners; electrical components including motor frames and end laminates, circuit breakers, controls and connectors; and home and power tool components, including heat shields and heat-resistant utensils.
