Production Description
Reinforced PBT formulation boasts high mechanical reliability,
dimensional consistency, and long-term color stability.
Environmentally certified (RoHS/REACH) and UL-recognized, it's
engineered for lighting structural parts, heat-dissipating
assemblies, and electrical insulation solutions.
The application fields are similar to thermal conductive PA, and it
is mainly used in large-sized lighting fixtures with high toughness
requirements
