Informação do produto

Easy-flow, glass fiber-reinforced polybutylene terephthalate compound with increased impact strength

VESTODUR® X4877 is an easy-flow, glass  fiber-reinforced (30%) polybutylene tereph­thalate compound (PBT) with increased impact strength for injection molding.

 

This compound is especially suitable for the manufacture of parts which are subjected to  high mechanical and thermal loads. Compared with commonly used glass fiber-reinforced

PBT compounds with a similar stiffness VESTODUR® X4877 has an increased impact strength and also a higher strain at break.

 

VESTODUR® X4877 is supplied as cylindrical pellets in polyethylene packaging.

 

For further information about processing of VESTODUR® X4877, please follow the general recommendations in our brochure "VESTODUR® Handling and Processing".

 

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.
