Superior polymer durability for your high performance thermoplastic needs
Celazole® T-Series products are PBI compounds designed for injection molding and extrusion. Combining the superior mechanical properties and thermal resistance of PBI with the melt process ability of polyaryletherketones (PEEK or PEKK), these products offer cost-effective high performance. These products are available in pellet form.
Celazole® PBI (polybenzimidazole) is a unique and highly stable heterocyclic polymer. PBI polymers are characterized by high thermal stability; exhibit high strength, broad chemical resistance and unique compatibility with certain other polymers including the polyaryletherketone family.
WEAR RESISTANCE
4x increase in light fixture production compared with polyamideimide
HIGH STRENGTH
TF-60C has 15,000 psi flex strength at 500°F (100 MPa flex strength at 260°C)
COST EFFECTIVE
T-Series products are 100% melt processable
