PBT Injection Molding
PBT resin offers excellent processability, electrical properties, and good surface finish quality
Polybutylene terephthalate (PBT) is semi-crystalline thermoplastic with excellent processibility and good mechanical properties, which make it a versatile general purpose resin for wide range of applications.
We offer three grades of PBT through our injection molding service:
- Valox 357: A polycarbonate/PBT blend that is a general purpose resin. It also has flame retardant with a UL V0 and 5VA rating.
- Valox 420 SEO (30% Glass Filled): A glass-filled PBT resin with flame retardant and well rounded mechanical properties.
- Crastin S600F20: Friction and wear resistance with excellent colorability.
