Performance materials - Polymer performance

What is the difference between standard polycarbonate and POLYSORB® isosorbide-based polycarbonate?

Standard polycarbonates are mainly composed of Bisphenol A, while by using POLYSORB® isosorbide, resin manufacturers can design special BPA-free polycarbonates.
Performance materials - Polymer performance

How can POLYSORB® isosorbide contribute to replace standard polycarbonate?

Using POLYSORB® as co-monomer in polyester resins like PET enables to create better performing materials.

With such improvement, they can pretend to be a BPA-free, safe plastic alternative to standard polycarbonate.
Performance materials - Polymer performance

What can be done to increase the glass transition temperature (Tg) of polyethylene terephthalate (PET)?

Polyethylene terephthalate (PET) glass transition temperature limits its use, notably in packagings subject to heating.

By introducing POLYSORB® isosorbide as co-monomer during the resin synthesis, PEIT (polyethylene-co-isosorbide terephthalate) resin is created. POLYSORB® isosorbide introduction boosts resin temperature resisitance, enabling the use of PEIT in new demanding packaging applications.

Performance materials - Polymer performance

What is POLYSORB® isosorbide impact on polymer glass transition temperature (Tg)?

Thanks to its original molecular design, POLYSORB® isosorbide often increase polymer Tg.

Performance materials - Safety

Are all POLYSORB® isosorbide-based plastics approuved for food contact?

Food contact regulation depends both on country regulation and plastic type.

It is recommended to contact the resin manufacturer to have more information on it.

Performance materials - Safety

How does Roquette provide Bisphenol A alternatives?

Roquette offers POLYSORB® isosorbide, a safe plant-based monomer that can be used to replace BPA, such as in polycarbonate.
Performance materials - Safety

How does Roquette provide Phthalates Alternatives?

Roquette offers POLYSORB® ID, a safe plant-based general purpose plasticizer that can be used to replace phthalate-based plasticizers, such as DINP.
Performance materials - Safety

Is PEIT (polyethylene-co-isosorbide terephthalate) a food contact polymer?

In Europe, isosorbide is listed as monomer that can be used to modify PET on "plastic materials and articles intended to come into contact with food" regulation.

Performance materials - Safety

Is POLYSORB® isosorbide diesters a non-phthalate plasticizer?

POLYSORB® ID structure is based on POLYSORB® isosorbide and plant-based fatty acids. By nature, it does not content any phthalate and is definitely a phthalate-free plasticizer.
Performance materials - Safety

Are POLYSORB® isosorbide-based plastics BPA-free?

POLYSORB® isosorbide does not contain any Bisphenol A and so is BPA-free.

Plastics based on isosorbide are produced with co-monomers. It is recommended to contact the resin manufacturer to have more information on it.
Performance materials - Safety

Is POLYSORB® isosorbide safe?

Yes. POLYSORB® isosorbide is registered in global chemical inventories like Reach or ToSCA and the toxicological assessment has shown isosorbide was safe, without any classification.

It is free of bisphenols (like BPA, BPS or BPF), no endocrine disruptive effect has been shown and in-vitro testing on other isosorbide esters had no effect.

Can LYCASIN® be used for diabetic formulations?

LYCASIN® has been classified in Europe as having a reduced caloric level of 2.4 Kcal/day.  For diabetic patients this is therefore a useful ingredient but one that has to be taken in amounts that observe the recommended glucidic intake.
