Highly filled PBT
General Electric Plastics say that recently developed “heavy” mineral-filled polybutylene terephthalate compounds will enlarge the realm of engineering plastics applications by adding the dimensions of weight and ceramic-like prope~ies. Called Heavy Valox by General Electric Plastics, two highly filled PEST grades for injection moulding are now commercially available.
