PBT

Polybutylene Terephthalate (PBT) is a semi-crystalline engineering resin known for its excellent heat resistance, chemical resistance, and electrical insulation properties. Its fast crystallization rate allows for short molding cycles, improving production efficiency. PBT also offers outstanding weather resistance, low friction, high wear resistance, excellent dimensional stability, and long-term thermal durability, providing a well-balanced combination of performance and cost efficiency.

The mechanical properties of PBT can be significantly enhanced through reinforcement with glass fiber and mineral fillers, making it well suited for flame-retardant formulations. Due to its minimal change in physical properties over long-term use, PBT is widely applied in precision components, including electrical and electronic parts such as TV components, connectors, and switches, as well as various automotive applications.

PET

Polyethylene Terephthalate (PET) offers excellent stiffness, thermal performance, dimensional stability, and superior surface gloss. It features a heat distortion temperature approximately 20 °C higher than PBT and low moisture absorption, enabling the production of high-performance components with tight tolerances and high-quality surface finishes.

PET is an ideal alternative to die-cast metals and thermosetting resins in applications requiring high rigidity and precision. It is commonly used in electrical and electronic products, including exterior parts, structural housings and frames, water-related components, transformers, and ignition coil housings.

Our product portfolio includes the following PET and PBT compound solutions.
