Production Description
Modified Polybutylene terephthalate (PBT) features excellent mechanical properties, good dimensional
stability, and strong resistance to yellowing. The products comply
with environmental requirements such as RoHS and REACH and have
passed UL certification. They are mainly used in plastic structural
components of lighting fixtures, including aluminum-clad plastic
heat dissipation components and all-plastic structural components,
as well as in coil bobbins and home appliances.
The application fields are similar to thermal conductive PA, and it
is mainly used in large-sized lighting fixtures with high toughness
requirements
