Exel to integrate Polynt’s bio-based monomers into its composite solutions

-

Exel Composites, a global technology company that designs and manufactures composite solutions, has partnered with Polynt, a leading global producer of specialties for industrial, transportation, building and construction markets, to integrate bio-based monomers into its composite solutions. This collaboration aims to develop more sustainable composite materials with a reduced carbon footprint.


Exel has entered into a new purchasing agreement with global resin specialist Polynt to purchase hundreds of tonnes of its bio-based unsaturated polyester resin (UPR). The collaboration represents another significant step in Exel’s transition towards lower-carbon composites manufacturing, with the resin available for European customers’ orders now. 

The resin, developed by Polynt, contains about 20% bio-based content thanks to the introduction of a renewable monomer. The Italian producer sources this monomer from second- and third-generation biomass; feedstocks that do not compete with food crops. This sustainable material offers a drop-in replacement for traditional fossil-based resins, ensuring full compatibility with Exel’s existing pultrusion processes. 

Compared with conventional UPR, independent lifecycle analyses (LCAs) show that the bio-based formulation delivers a 20% reduction in carbon footprint according to Ecoinvent v3.11. Polynt sources the monomer in Europe and produces most of the raw materials in its Italian plants. The resin is produced in Polynt’s production facilities in Poland and France, and will be used in Exel’s European plants. This ensures minimal transportation-related emissions throughout the entire supply chain. 

“Our internal testing shows no measurable difference in performance between this bio-based resin and the fossil-based equivalent.


Exel and Polynt share a similar global footprint, with multiple production sites across the world. This regionalised structure allows both companies to supply customers locally, reducing delivery times and logistics-related emissions. 


Polynt is committed to helping customers like Exel reduce their environmental impact through practical, scalable solutions. Introducing bio-based building blocks into high-volume resin systems is one of the most effective ways to move our industry toward lower emissions.” 

Exel’s customers will have the choice of adopting this resin as part of their product specification. By working with long-term partners such as Polynt, Exel continues to advance sustainable manufacturing in composites. For contractors bidding for tenders, lower-carbon materials can be an excellent way to increase their proposal’s appeal.

Today's KNOWLEDGE Share What Is Going Wrong in UK Plastics Recycling? Biffa shut its Sunderland plant. Viridor walked away from Avonmouth and Rochester. Yes Recycling Fife collapsed within a year. All three were backed by major investments All three had buyers lined up for recyclate All three are now offline This is not bad luck It is bad structure Over the next four posts I will break down: 1. Why cheap virgin imports are undercutting UK recyclers 2. How weak policy enforcement is fuelling market failure 3. What volatile PRNs and cheap exports are doing to infrastructure 4. Why demand from brands is softer than their promises Let’s start with the first: **Cheap Virgin Resin = Broken Economics** Virgin PE, PP, and PET have been flooding the global market. New capacity in Asia and the US has driven prices down 30 to 40 percent. Meanwhile, recycled plastic costs more to produce in the UK than it can sell for. We are asking UK recyclers to compete with materials made in places with – ...

Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...
