INVITATION TO DSM PRESS CONFERENCE Today at 10 a.m. DSM holds a press conference in which Jos Goessens, President of DSM Engineering Plastics and Frans Pistorius, President of DSM Nederland, will elaborate on the investments at Chemelot. The press conference will take place in DSM's Mauritspark office, Mijnweg 1, Geleen. Those who are not able to attend in person are invited to follow the presentation via a live audio cast in Dutch only at www.dsm.com.

Royal DSM N.V. today announces that it has decided to construct two new manufacturing facilities at its Chemelot site in Geleen, the Netherlands. DSM is making these investments in response to excellent market growth for two of the company's top specialty products, Stanyl® polyamide 46 and Stamylan® UH ultra-high molecular weight polyethylene, which is used among other things as a raw material for Dyneema® high strength fibers. The new Stanyl® plant and the new Stamylan® facility, which will each double existing production capacity, are scheduled to come on line in 2008. The total investment will be around EUR 100 million.

The high performance material Stanyl® is used in a variety of applications, such as automotive, cell phones, computers and personal electronics. In addition, there is rapid growth in new, innovative applications such as fine pitch connectors for LCDs, reflector packages for LEDs, and gears in all kind of applications, for example seat recliners and starter motors. Stamylan® UH is used as a high strength, wear-resistant engineering plastic in industrial, sports and other applications and in Dyneema®, the world's strongest fiber(TM). This new investment will secure supply to DSM's growing Dyneema® fiber business and will make it possible to meet the sourcing requirements of other customers.

"These investments are another major step in the context of DSM's strategy Vision 2010 - Building on Strengths," says Nico Gerardu, member of DSM's Managing Board. "They will fuel the profitable growth of our specialty performance materials Stanyl®, Stamylan® UH and Dyneema® and build on our strengths in marketing and application development of these products."

DSM is the sole worldwide producer of polyamide 46. With the new Stanyl® plant, DSM will operate two Stanyl® plants at the Chemelot site in Geleen to supply Stanyl® base resin worldwide to DSM's operations in Europe, USA, Japan and, most recently, China.

"Production of Stanyl® base resin is supported by our ability to manufacture our own high-purity diaminobutane," commented Jos Goessens, President of DSM Engineering Plastics. Diaminobutane is the key monomer in the production of Stanyl®. DSM has also decided to start the basic engineering to debottleneck the diaminobutane plant in Geleen, to match the increased production capacity for Stanyl l®. "With the second Stanyl® facility and the capacity expansion for diaminobutane, we can secure the supply of Stanyl® to support the excellent growth of our customers worldwide in the years ahead," added Goessens.

"The fact that DSM is making these major investments at the Chemelot site in Geleen, its biggest and oldest manufacturing site, shows the competitive power of this site and also demonstrates DSM's commitment to it. These investments will give another boost to our site and to the economic growth of the region," commented Frans Pistorius, President of DSM Nederland.

Stanyl® Stanyl®, the highest performance polyamide in the world, is a unique, high-crystallinity material that exhibits exceptional heat resistance, stiffness and strength, chemical resistance and processability. In addition, it has a low coefficient of friction and resists creep and deformation. Automotive applications of Stanyl® include chain tensioners, engine covers, gears, sensors and clutch rings. Electrical applications include connectors, circuit breaker housings, microswitches, electric motor parts, and a variety of components for consumer electronics. Consumer applications include muffler covers for gas operated tools, water kettle components including safety switches, and a variety of other hand and power tool components.

Stamylan® UH Stamylan® UH is a very high molecular weight polyethylene that exhibits excellent toughness and resistance to abrasion, outstanding chemical resistance and good low friction, non-stick characteristics. It is widely used for wear-resistant components in industrial, bulk materials handling and sports equipment as well as in ultra-strong fibers.

Dyneema® Dyneema® is a super strong polyethylene fiber that offers maximum strength combined with minimum weight. It is up to 15 times stronger than quality steel and up to 40% stronger than aramid fibers, both on a weight-for-weight basis. Dyneema® is an important component in marine and offshore ropes, in cables and nets, in safety gloves for the metalworking industry and in fine yarns for applications in sporting goods and the medical sector. In addition, Dyneema® is used in bullet resistant armor and clothing for police and military personnel.
