Medium viscosity polybutylene terephthalate resin with processing aids

VESTODUR® X4621 is a medium viscosity, fast solidifying polybutylene terephthalate resin (PBT).
 

VESTODUR® X4621 can be used for the injection molding process. 

 

The resin is supplied as cylindrical granules, ready for processing.

 

For information about VESTODUR® X4621, please follow the general recommendations in our flyer “VESTODUR® Polybutylene terephthalate - Compounds”.

 

Pigmentation may affect values.

Inside the original and undamaged packaging, the product has a shelf life of at least 2 years when stored in dry rooms at temperatures not exceeding 30°C.
