Bio-based epoxy prepreg

Syensqo has developed a new version of its flagship MTM 49-3 resin that contains 30% bio-sourced monomers. The new product variant complements the portfolio of the company’s MTM advanced prepregs and targets structural automotive applications, including body panels, chassis components and spoilers. The bio-based MTM 49-3 is being introduced to the market at JEC World 2024 from 5 to 7 March.

Just like the incumbent material, Syensqo’s new bio-based MTM 49-3 has a dry glass transition temperature (Tg) of 190 °C, and it exhibits enhanced toughness for superior impact resistance versus competitive thermoset prepregs. Thanks to its high strength-to-weight ratio, it can yield component mass savings of up to 40% over metals. The product is compatible with autoclave and press-conversion processes and achieves curing at 135 °C within 60 minutes. In addition, it has been designed for operator safety, and is free from carcinogens, mutagens or reproductive toxins.

“Our new bio-based MTM 49-3 will help OEMs and Tiers to reduce fossil depletion and meet their carbon neutrality goals, while ensuring the same high levels of quality, processability and mechanical performance as its original counterpart,” stated Greg Kelly, Head of Composite Product Management at Syensqo.
