High crystallinity enabling rapid solid-state polymerization and excellent melt stability.
Outstanding thermal resistance with decomposition onset above 380 °C under nitrogen atmosphere.
Low inherent viscosity drift during storage, ensuring consistent processing behavior over time.
Excellent compatibility with common nucleating agents and reinforcing fillers for engineered composites.
Controlled hydrolytic stability suitable for moisture-sensitive extrusion and injection molding processes.
High-performance engineering thermoplastics for automotive under-hood components.
Electrical insulation parts requiring long-term thermal endurance (e.g., connectors, housings).
Durability-critical industrial gears and bearing cages.
Food-contact compliant packaging trays requiring high rigidity and heat resistance.
Specialty fibers for technical textiles demanding dimensional stability at elevated temperatures.
