Definition - What does Polycaprolactone Thermoplastic Polyurethane (Polycaprolactone TPU) mean?

Polycaprolactone Thermoplastic Polyurethane belongs to a class of polyurethane plastics known for their many desirable properties including resistance to oil, grease, and abrasion. Polycaprolactone TPUs can be produced with low molecular weight distribution (MWD), low acid values, and excellent end-termination functionality.

Overall, Polycaprolactone TPUs offer a level of performance between polyester and polyether-based TPUs.

Polycaprolactone thermoplastic polyurethane is also known as polycaprolactone TPU or simply PCL.

The attributes of polycaprolactone manifest themselves as several material properties including:

  • High resistance to hydrolysis
  • Inherent durability, and cut/chip resistance
  • Low-temperature flexibility and toughness
  • Chemical resistance

Polycaprolactone compounds can be custom-tailored to meet individual performance specifications in several harsh environments. The mechanical features of this thermoplastic and the even-numbered carbon spacing give it structural characteristics that surpass polyester-polyurethanes.

Polycaprolactone is most commonly used for the manufacture of pneumatic and hydraulic seals, and conveyor belts.
