Ultradur® High Speed: First BASF plastic with eco-efficiency label
Siemens test mould: Ultradur® High Speed has better flowability
Just one year after its market introduction, Ultradur® High Speed, BASF's new especially easy-flowing PBT (polybutylene terephthalate), has become the company's first engineering plastic to receive the so-called eco-efficiency label. Studies have demonstrated that products made of Ultradur® High Speed are considerably more eco-efficient than products made of a standard PBT. The good flowability of this new material not only makes the production of injection-moulded plastic components cheaper but also helps to save energy, thus protecting the environment.
The eco-efficiency label is awarded to products or methods that perform better from an environmental and financial standpoint than comparable products or methods. With an eye towards this, the product undergoes an Eco-Efficiency Analysis certified by the German Technical Control Board (TÜV) of Rhineland/Brandenburg in accordance with specified guidelines. The analysis is subsequently submitted for a critical review by an independent third party in accordance with DIN ISO 14040 to 14043. In the case of Ultradur® High Speed, it was Professor Hungerbühler of the Swiss Federal Institute of Technology (ETH) in Zurich, Switzerland, who wrote the expert opinion. The eco-efficiency label is then valid for the products examined in the analysis and applies to the customer benefit as defined in the Eco-Efficiency Analysis. The results have to be reviewed once again after three years since the market situation and other boundary conditions might have changed.
Eco-efficiency analysis for Ultradur® High Speed
Processors benefit from the flowability of Ultradur® High Speed, which has been markedly improved by incorporating a nano additive, since the processing temperature as well as the injection and holding pressures in the injection-moulding machine can be lowered. Energy savings of up to 20 percent can be realized here. As an alternative, the cycle time can be reduced by up to 30 percent. The mould can have a simpler design and new parts can have thinner walls, thus saving a considerable amount of material. The number of rejects also drops since it is now easier to fill the mould with this easy-flowing plastic. All in all, this makes Ultradur® High Speed the favourable product, both in terms of cost and environmental impact.
In 2005, BASF augmented the Eco-Efficiency Analysis by developing a computer program with which the customer can have the advantage precisely calculated that results from a substitution of standard PBT against Ultradur® High Speed under his specific production conditions. This tool is called the eco-efficiency manager and it allows BASF sales personnel to go directly to the customer's premises and perform this calculation.
