Roquette plant-based solutions for TPU: empower your softness!

POLYSORB® isosorbide is a diol that can be used in polyurethane technologies, either directly in the formulation: TPU (Thermoplastic Polyurethane) or PU foams (Polyurethane foams), or once transformed into a polyester polyol (coatings).

POLYSORB® isosorbide for TPU

TPU are flexible engineering plastics composed of two phases: a rigid one and a soft. POLYSORB® isosorbide is a low molecular weight diol that can be used as a chain extender in order to create a rigid phase in certain Thermoplastic Polyurethane (TPU) applications: industrial rollings, sports & leisure goods, casing, etc.

POLYSORB® isosorbide improves TPU performances by increasing Tg without compromising softness and reducing coloration.

POLYSORB® isosorbide for Coatings

POLYSORB® isosorbide can also be introduced in the synthesis of polyester polyols for use in coating applications. For more information on the use of POLYSORB® isosorbide in coatings and composites and resins, click here (lien vers page composite & coatings.
