PIBIFLEX® – TPC-ET from Celanese

K.D. Feddersen Is Your Distributor for PIBIFLEX® TPC-ET from Celanese

Good Low-temperature Flexibility and Chemical Resistance

PIBIFLEX® from Celanese are thermoplastic polyester elastomers that combine the material properties of crosslinked elastomers with the ease of processability of thermoplastics and are characterised by their outstanding impact strength, strength, wear resistance and elasticity.

PIBIFLEX® types are available with different grades of Shore hardness from 25 to 75. The softer versions retain their good mechanical material properties even at low temperatures, whereas the harder versions have improved temperature and chemical resistance.

The thermoplastic elastomers can be used within a wide temperature range and also have excellent resistance to many fuels, solvents, oils, greases and diluted acids and bases. Further beneficial properties of PIBIFLEX® are their good creep resistance, impact and fatigue resistance.

With PIBIFLEX®, Celanese offers a large selection of polyester elastomers with a broad spectrum of properties for a wide range of requirements and applications, for example in the automotive sector. Many types have a high degree of cold flexibility and are therefore suitable for sport and leisure applications.
