NEW HIGH FLOW STANYL GRADE FROM DSM FOR JET ENGINE PARTS
07 July 2004 - DSM Engineering Plastics

DSM Engineering Plastics announces the availability of a new grade of high-flow Stanyl polyamide 46 (PA46) designed for elements of aircraft jet engines.

Stanyl 46HF4130 is a 30% glass-fibre-reinforced compound that was initially developed for use in the intake portion of the Rolls-Royce Trent 900 engine, engineered for noise reduction and minimum environmental impact. The engine uses 50 panels with highly complex geometry to minimize noise through a complex section of the engine duct, benefiting from Stanyl’s high strength and mouldability.

Moulded Stanyl thermoplastic components replace hand-built, glass-reinforced plastic (GRP) parts. Thin and large - up to 40 cm in length, yet only 0.8 mm thick in places - the components must be able to withstand the impact of bird strikes at temperatures ranging from 50 to 150C, as well as resist warpage.

'Extensive testing of candidate materials resulted in the selection of Stanyl for infill panels on the Trent 900 engine. Stanyl proved to have the right balance between lightness and strength,' says Neil Williams, spokesperson of Rolls-Royce. “Using high-performance thermoplastics like Stanyl has been an optimum solution for both performance and cost in this important application.”

Development of the design, material, and moulding was a joint effort among DSM Engineering Plastics, toolmaker and moulder Stuckerjurgen, and the Austrian systems supplier FACC.

The Rolls-Royce Trent 900 engine is used on the large Airbus A380 passenger aircraft.

In addition to its use in jet engines, Stanyl 46HF4130 is also well-suited for connectors and other intricate parts featuring thin sections or complex geometries. Stanyl materials have unique property profiles that provide the best solution for many applications needing outstanding performance.

Stanyl grades are based on polyamide 46, a highly crystalline material with a melting temperature of 295C. Its toughness and high mechanical strength combined with exceptional flow gives the widest design freedom possible in engineering plastics. Stanyl grades are widely used in automotive and electronic applications because it has proven that it can meet the critical demands of those industries and at the same time deliver value through more reliable performance and lower system costs.

Applications for Stanyl grades include charge air coolers and chain tensioners, bearing cages, electrical connectors and components, electric motor end laminates and brush holders, and a variety of housings and shields for home appliances, lawn and garden tools, and building products.

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.
