DSM Engineering Plastics launches Stanyl® PA46 High Flow™

New polyamide grade rounds out DSM’s flagship product family, brings mouldability as well as high heat and warp resistance to electronics and other demanding applications.

DSM Engineering Plastics, a business group within the DSM Performance Materials cluster, announces the introduction of Stanyl® PA46 High Flow™. With a heat and warp resistance similar to liquid crystal polymer (LCP), plus high flow characteristics for thinwall or highly detailed parts, Stanyl PA46 High Flow significantly lowers the cost of engineered materials for volume production.

Stanyl PA46 High Flow is the latest addition to DSM’s flagship Stanyl PA46 product family, and is particularly suited for thinwall applications in E&E. These include electrical connectors, pin headers, and more, thanks to the new material’s flow characteristics and resistance to warpage. Weld line strength is significantly higher than LCP, minimizing cracking during pin insertion. For demanding thinwall applications, Stanyl High Flow grades can replace LCP, providing the properties of LCP at substantially reduced cost.

As with all Stanyl PA46 offerings, Stanyl PA46 High Flow provides resistance to distortion at high heat to 290°C (554°F) - as well as superior mechanical properties, excellent wear and friction behaviour, and production cycle times shorter than conventional polyamide 6 and 66. In other applications, Stanyl is also used for automotive parts such as engine parts, chain tensioners, transmission clutch rings, bearing cages and emission control components. Finally, there are many other electrical, appliance, and power tool uses for Stanyl PA46 High Flow.

Stanyl PA46 High Flow rounds out DSM’s PA46 offering, which includes reinforced, lubricated, low-wear/low-friction, and flame-retardant (FR) grades. Anything that can benefit from thinwall or highly detailed parts that must face demanding ambient or use conditions can benefit from High Flow.

Production for one DDR-DIMM module (double digit rate - dual inline memory module) showed the following characteristics:

general purpose FR grade for connectors etc

HF5041LW
low warpage grade FR for memory modules/ parts where flatness and coplanarity are important

HF5050
higher stiffness and lower warp alternative to the GP grade - also FR

HF4130
non FR grade for auto and other industries, for complex metal replacement designs where temperature resistance, stiffness,
strength and toughness are required

Notes for editors

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 and PC-blends, 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 579 million in 2002. DSM Engineering Plastics has a market share of about 5% in the world market. With Stanyl®, it is the global market leader in high heat polyamides.

DSM N.V.

DSM is active worldwide in life science products, performance materials and industrial chemicals. The group has annual sales of close to EUR 5.6 billion and employs about 18,500 people at more than 200 sites across the world. DSM ranks among the global leaders in many of its fields. The company’s strategic aim is to grow its sales - partly through acquisitions - to a level of approx. EUR 10 billion by 2005. By that time at least 80% of sales should be generated by specialties, i.e. advanced chemical and biotechnological products for the life science industry and performance materials. This strategy represents a continuation of the company’s ongoing transformation and concentration on global leadership positions in high-added-value activities characterized by high growth and more stable profit levels.
