INNOVATIVE WITH, our magazine with the ideas of the future

Catch up on the full potential of the Elium® resin in the second issue of our INNOVATIVE WITH magazine. Thermoplastic, liquid, easy to process and designed to make composites fully recyclable, Elium® resin ticks all the boxes. A unique resin in the world for thermoplastic composites, whereas traditional thermoset-based composites, widely used in many applications for their light weight and sturdiness, have the disadvantage of not being recyclable at their end-of-life. This innovation is going to revolutionize the wind power, boat-building, hydrogen tank, and concrete reinforcement sectors. But then, for the best testimonies, read our partners’ and customers’ opinions in this latest edition!

How Elium® thermoplastic resin works

  • Formulation: Elium® is a acrylic base polymer diluted in a reactive monomer blend with processing additives that makes it very fluide 
  • Polymerisation: a polymerisation initiator is mixed with the resin to create an high molecular weight thermoplacstic matrix. Several type of reaction and intitiators are possible
  • Process: as a thermoset resin used in composites fiber reinforced polymer. Elium® is compatible with traditional process and the parameters can be adjusted depending on the requirements (viscosity, time and temperature reactivity)
  • Applications: our solution enables to obtain high performance composites products like epoxy, polyester or vinylester with all the benefits of thermoplastic matrix. Industries: wind energy, construction and civil engineering, transportation, marine, sports and consumers goods
  • End of life: Elium® can be recycled with 2 methodologies, mechanical or chemical, to produce new recycled composites parts.

 

Benefits of Elium® thermoplastic resin

A composite part made with our Elium® resins:

  • Is light and tough with superior properties under impact
  • Is Styrene free, contains no BPA and cobalt salts
  • Is fully recyclable with possible separation of the fibers and reuse of the virgin resin
  • Has a cost efficient and lower Capex compared to similar thermosets parts
  • Has additional features and benefits for adhesion, welding, thermoforming.
 

 

Explore our solutions to recycle composites parts using Elium® resin

In 2017 our R&D teams were heavily involved in developing the recycling process for composite parts made from the Elium® resin via depolymerization. The principle entails coarsely crushing the parts; the Elium® resin is then heat-depolymerized so that it can be recovered and purified into a resin with the same properties as the virgin resin. Meanwhile, the remaining carbon or glass fibers can be reused.

Being able to recycle parts made from Elium® resin is a tremendous asset, in particular for wind turbine manufacturers who currently use non-recyclable epoxy resins to manufacture the blades.

 

Will composites transform industry?

Over the past few decades, composite materials have penetrated all sectors of industry. In a market ultra-dominated by thermosetting composite materials, thermoplastic composites are gradually making their mark.

And future innovations, in particular with regard to recycling, should enable them to gain a lasting foothold.
