Celanex^®

Product Finder

Celanex^® thermoplastic polyester (PBT) is a semicrystalline structure based on polybutylene terephthalate that provides high strength, rigidity and toughness, low creep even at high temperatures and resistance to a wide range of chemicals, solvents, oils and greases.

Celanex^® PBT is especially suited as a sliding partner for Hostaform^®/ Celcon^®POM. It features excellent dimensional stability, low moisture absorption and powerful insulation resistance.

Product Properties:

Very hard, rigid and strong
Good creep resistance
High heat-distortion temperature, especially for glass fiber-reinforced grades
Service temperature to 140°C
Very good low-friction and wear-resistant properties
High dimensional stability (low thermal expansion coefficient, low water absorption)
Good electrical properties
Good chemical resistance
No environmental stress cracking
Good weathering resistance
Rapid crystallization and fast cycle time
Paintable
Flame-retardant grades available (UL 94 V-0, in some cases 5VA)

Depending on market requirements, the Celanex PBT flame-retardant system is low in migration and halogen-free.

Grades:

Basic
Glass fiber and glass sphere reinforced
Glass fiber reinforced with very high surface gloss
Glass fiber/mineral reinforced
Flame retardant
UV stabilized
HR grades
Medical technology (MT^®)
Special colors for laser marking
MetaLX^™ metal effects

Processing:

Injection molding
Extrusion
Meltblown
Physical foaming
Water and gas injection technology (WIT/GIT)

Various grades of Celanex PBT hold regulatory approvals including VDE or UL approvals for the electrical and electronic market, and FDA approval for the nutrition and medical markets.
