Hexion Stuttgart has introduced the Hexi-Bag packaging system, a new large-volume resin package designed specifically for the wind energy industry. The new packaging format was developed for Hexion’s epoxy adhesive resins and associated hardeners. It provides wind blade manufacturers with several efficiencies and cost advantages.
By using the Hexi-Bag, it is possible to save up to 80% on wind-related transport costs.
The capacity of the new Hexi-Bag is 900 to 1,000 liters and approximately five times larger than the standard barrel, addressing the large volumes of resin required to produce rotor blades. In addition, use of the Hexi-Bag reduces residual material in the packaging to less than 1%, versus the 5 to 10% waste associated with traditional packaging.
In addition, the Hexi-Bag can result in reduced internal shipping costs.
“Over the past 10 years, the average length of a rotor blade has grown from 45 to 60 meters. As the resin volumes required for each blade continue to increase, it’s a logical step for us to provide more efficient, larger volume packaging solutions for our customers,” said Senior Project Manager Karl Eichler.
Hexion Stuttgart has entered into an exclusive partnership with the Finnish company Fluid-Bag to provide its customers with an appropriate transfer station for material change. Hexi-Bag was used for the first time by Carbon-ROTEC, an independent manufacturer of high-quality rotor blades for wind turbines and components made of composite materials.
“When using the Hexi-Bag, not only is less material lost to waste, it’s also possible to save up to 80% on internal transport costs. These cost savings can provide advantages to customers in the competitive wind-power industry,” Eichler added.
