how to increase the elongation @break for the polycaprolattone ? PCL was used in thermoforming applications and needs to improve elongation @break to avoid cracks after forming step. Some plasticizer can be used ?
Yes, plasticizers are a good idea.
However, did not work with plastic materials recently (more than 10 years, even then not much).
It is not a direct answer but here is one (excellent) paper with a similar topics:

Dear all, blending with other pilymers is another option. Also, moderate molecular weight PEG's are used as polymeric plasticizers. My Regards
The following document seems intersting.

Hi. See the below article :

Hi;
High levels of epoxidized natural rubber containing 50 mole percent of reactive epoxy sites significantly improve the elongation at break of PCL. Please see the attached document.
With my best regards
