The smell is the third stage of our journey through the “5 senses of TPE”.
It doesn’t happen rellay often, but sometimes we realize the importance of things only when we notice their absence. This is the case with smell.
How should aTPE smell? Basically, it should have no smell.
For this reason, the olfactory impact is strictly linked to the formulation choices of the compound starting from the raw materials sourcing used in its production and the selection of processing conditions.
SEBS-based TPEs, for example our MARFRAN® E which are suitable for contact with food or our medical grades MARFRAN.MED®, are odourless thanks to the careful selection of raw materials and production processes.
Besides, there is also the possibility to add various fragrances to give the TPE and to the injection moulded product the scent desired.
