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!
Elium® resins properties
Characteristics of our Elium® resin:
- 30 to 50% lighter than the same parts made from steel with the same resistance
- Perfect for complex design forms
- Seamlessly blends with glass or carbon fibers
- Compatible with conventionial thermosetting resin transformation technologies (Resin Transfer Moulding, Infusion, Flex-molding)
- Exceptional post-thermoforming (welding and gluing)
- Styrene free compared to unsatured polyesters
- Parts easily thermoformed and recycled with comparable mechanical performance for epoxy parts
- Cost less to manufacture compared to other thermoplastic technologies
- Conventional thermoset resin processes
- Transformation at room temperature
- No organo-sheets.
Recycling composite parts made of Elium® resin is possible!
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.
