Is POLYSORB® isosorbide a bio-based monomer?
Are POLYSORB® isosorbide-based polymers considered as bio-based polymers?
However, polymers based on isosorbide are produced with other co-monomers.
It is recommended to contact the resin manufacturer to have more information of final bio-based content of the material.
What is a chain extender?
A chain extender is a short chain diol used in polyurethane-based thermoplastics (TPU) to create hard blocks.
TPU special properties are highly linked to the presence of such blocks.
What is POLYSORB® isosorbide?
POLYSORB® isosorbide is a cycloaliphatic monomer obtained from sorbitol dehydratation.
Sorbitol is a polyol obtained from glucose, the starch monomer.
Starch is the main component of plant-based raw materials such as maize, wheat,…
Is POLYSORB® isosorbide a chain extender?
What can be considered as a POLYSORB® isosorbide derivative?
POLYSORB® isosorbide has a unique diol structure that enables molecule grafting or polymerisation.
All compounds based on chemical modification of POLYSORB® isosorbide can be qualified as isosorbide derivative.
Is POLYSORB® isosorbide suitable for polyester resin modification?
Who is Roquette?
Is POLYSORB® ID a bio-based plasticizer?
Does the "7" resin identification code on plastic mean they contain POLYSORB® isosorbide?
What is the resin identification code (RIC) for isosorbide-based plastics?
Are POLYSORB® isosorbide-based polymers UV resistant?
Thanks to its non-aromatic (cycloaliphatic) structure, POLYSORB® isosorbide does not introduce into polymers UV sensitive bonds, enabling higher UV resistance to plastics.
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.
