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
