What is the difference between standard polycarbonate and POLYSORB® isosorbide-based polycarbonate?
How can POLYSORB® isosorbide contribute to replace standard polycarbonate?
With such improvement, they can pretend to be a BPA-free, safe plastic alternative to standard polycarbonate.
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.
What is POLYSORB® isosorbide impact on polymer glass transition temperature (Tg)?
Thanks to its original molecular design, POLYSORB® isosorbide often increase polymer Tg.
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.
How does Roquette provide Bisphenol A alternatives?
How does Roquette provide Phthalates Alternatives?
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.
Is POLYSORB® isosorbide diesters a non-phthalate plasticizer?
Are POLYSORB® isosorbide-based plastics 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.
Is POLYSORB® isosorbide safe?
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.

What is the typical level of lubrication required for tableting with mannitol PEARLITOL® SD?
The level of lubrication required depends on many variables, notably the physical nature of the powder mixes. For PEARLITOL® Mannitol the recommended level of lubricant can be up to 1.5 - 2.0% of magnesium stearate, in particular for unusual tablet shapes.
