Meet the next generation of wind blade performance

Using our DNV-GL certified ProxximaTM polyolefin thermoset resin system to create wind turbine parts reduces the overall weight, improving energy generation efficiency and extending the service time. The high fracture toughness and good fatigue performance helps blades withstand damage and last longer. A recent third-party study (in critical review) indicates our ProxximaTM resin system has a significantly reduced cradle-to-gate carbon footprint compared to other traditional thermosets.

Processing advantages

The intrinsic low viscosity and controlled, fast cure of our ProxximaTM resin system makes it possible to build high-performing blades while increasing plant throughput. The lower density also reduces the weight, and the low exotherm enables process optimization when producing thicker parts. 

ProxximaTM is DNV certified and is proven across all wind blade components (spar caps, shear webs, roots, and foils). ProxximaTM resin systems also have good compatibility with existing materials used in wind blades components.  Combined, these attributes enable Proxxima-based components to be easily integrated into existing designs to help improve blade fabrication.

ExxonMobil has made blades of commercial size at the Fraunhofer Institute for Wind Energy System, and we are able to share the production conditions with you and demonstrate the gains in productivity.

Processing advantages at a glance:

  • 5x faster infusion time due to ultra-low viscosity.
  • Improved productivity due to quicker cure cycle.
  • Less scrap due to fewer necessary inlets.
  • Resilience during infusion due to long open time.
  • Energy savings due to no resin pre-heating necessary. 
  • Less complexity due to temperature-stable formulation.
  • Potential for further design optimization due to superior performance at less weight.

Produce high quality thick parts with ease

Process thick parts (such as spar caps) and parts with high fiber density with ease by using our ProxximaTM resin systems. Their super-low viscosity enables excellent fiber wet-out, and the low peak exotherm produces laminates of higher quality. The result is a lighter part with a superior balance of strength and toughness. Our systems are designed to enable thick lamination with both carbon and glass fiber, allowing design flexibility. We have systems customized for both VARTM and pultrusion.

A solution we can feel good about

At ExxonMobil we are committed to delivering solutions for a more sustainable future by enabling industry-changing progress. A recent third-party study (currently in critical review) indicates that our ProxximaTM resin system has a significantly reduced cradle-to-gate carbon footprint compared to other traditional thermosets. We also have work underway to further reduce our footprint as we scale. Contact us to hear more.

The reduced weight, improved performance, extended service time, and potential for factory scrap recycling is expected to provide amplifying benefits if the carbon footprint study was extended to cradle-to-grave.

our products

Proxxima™ polyolefin thermoset resin systems

Our resin formulations are based on cyclic C5 monomers and other proprietary monomers and additives. Our catalyst formulations have strong foundations in Nobel Prize-winning technology developed by Professor Robert Grubbs and his research team. This powerful combination produces polymers that have the capability to outperform today’s solutions across a broad set of everyday applications such as wind turbine blades, electric vehicle parts, sustainable construction, and anticorrosion coatings.
