DSM Introduces New Offerings for Wind Turbine Blades

22 October 2010

At the China Wind Power show, DSM outlined their new solutions-based approach for the global wind turbine blade manufacturing industry.

At the heart of DSMs new approach is a move to educate the wind energy industry on the benefits and long-term potential of switching away from the traditionally used epoxy resins towards polyester resins for wind turbine blade manufacturing.

DSM also launched a new, advanced specialty resin material specifically developed for wind turbine blade applications. The new high-performance resin, Synolite 1790-G-3, was developed and tested in cooperation with major industry players and was officially launched at the China Wind Power show.

According to DSM the advantages of polyester resins in blade manufacturing are primarily to be found in faster-cycle times and improved energy efficiency in the production chain. Whilst the trend towards longer blade lengths, structural strength, lower weight, performance and durability is demanding better performing material options, DSM say that the performance properties of UPR (Unsaturated Polyester Resins) meet these requirements and it is a proven material in blade sizes of up to 3.5 MW turbines, or over 45 M length.

The complete solution package offered to blade manufacturers consists of consultancy and technical support spanning the entire production process of wind turbine blades from resin choice to mould and blade design to processing technology. DSMs service will include advice on reinforcement type and adhesives used, gelcoats and specific coating systems.

DSMs new approach will involve working with select, key partnerships such as Global Blade Technology, on the design of UPR based blades and molds.

We are highly impressed with DSMs knowledge of the industry, combined with their ability to develop materials to meet customer needs. We believe our knowledge and experience in blade design and manufacturing technology will help provide alternative designs for blades based on UPR resins. Together we offer a complete service to our customers, said Jan Willem van der Werff, CEO at Global Blade Technology.

This cooperation is an important element in our strategy to grow the application of our products in the wind turbine blade market. We are confident we will be able to leverage the experience and expertise of GBT to offer a unique package to the industry, said Michael Effing, President of DSM Composite Resins.

This is a radical and new approach to the market, says Effing. We are now a complete solutions provider of specialty UPRs supported by the industrys most extensive knowledge and support capability working in close partnership with leading industry players. This move underlines how committed we are to the global wind turbine blade manufacturing industry and to contributing generally to more sustainable energy production with our material innovations.

Effing further said: China will continue to be a strategically crucial market for DSM Composite Resins and we are fully committed to growing our customer support capability here.

The global wind power market grew by 31% in 2009, but in China installed capacity grew by 100 %. We believe we can grow our share and bring greater value to blade manufacturers through our new solution package supported with our dedicated resources in marketing, sales, manufacturing and R&D in our Shanghai and Nanjing technical centres.
