Biocompatible and Low Extractability Polybutylene Terephthalate PBT Resin

Dongguan Forever Co.,Ltd is the manufacture of the China origin cheap UV stablized PC polycarbonate Granules Polymer Resin


The WF006JiQ-XH compound is a high-quality PBT resin. It is composed of at least 37% of post-consumer recycled (PCR) materials

by weight and includes 30% glass fiber for added strength. 


This grade offers various benefits such as biocompatibility (ISO10993), low extractables, and suitability for healthcare applications. 

Furthermore, it exhibits excellent strength, stiffness, and dimensional stability.
