Copolyester and Polyamide Block Copolymers

Tight Supply Situations in the Past and Future Supply Outlook 

TPU price competition has increased as product differentiation among different TPU sources has decreased, due to TPUs hecoming more like commodities. 

The supply of TPU is increasing throughout the world. For example, Bayer produces TPU in Walsrode, Germany Dormagen, Germany Deerfield, MA New Martinsville, WV Sakai, Japan and Cuddalore, India. 

The exact chemical identity for this class of TPE is varied and many times proprietary. 

The copolyesters were developed early while the polyamide block copolymers are more recent in their development.
