Polyesters PET - PEIT
Innovate in the packaging market is a key to success! Go beyond PET towards PEIT with our plant-based POLYSORB® - the high purity isosorbide.
If you are working to improve the qualities of your PET by offering innovative, high-quality materials that are both transparent and resistant to temperature, our high-purity monomer POLYSORB® will enable you to achieve the characteristics demanded by the market.
Traditional modified polyester resins use specialty diols such as CHDM (cyclohexanedimethanol) or TMCD (tetramethyl-cyclobutanediol).
PEIT (Polyethylene co-Isosorbide Terephthalate) synthesized with highly pure POLYSORB® exhibits significant improvements in high temperature resistance (increase of glass transition temperature -Tg) at a low level of introduction at the same time as retaining material semi-cristallinity.
Increasing the isosorbide content will enable your material to reach Tg that is equal or even superior to 100°C without compromising on resin properties such as transparency and mechanical resistance.
Polyesters based on our POLYSORB® are often characterized by their attractive appearance and their resistance to daily chemical and physical attacks.

High purity isosorbide is a commercially available bio-based diol (POLYSORB®, Roquette, France) with a very low carbon footprint that can be incorporated in polymers to improve thermal properties, notably to increase Tg, alongside environmental impact.
A bio-based, sustainable, renewable monomer. Safe, non-toxic, with a low VOC, perfect as BPA alternative, it enables the production of recyclable, biodegradable or compostable plastics.
Case study: Incorporating isosorbide to develop eco-friendly polyesters with exciting potential for hot fill and cosmetic packaging.
Composites & coatingsSustainable and high quality thermosetting resins are increasingly demanded by the markets.
