Pellethane
Pellethane is a family of medical-grade thermoplastic polyurethane elastomers. It has superior resilience, low temperature properties and exceptionally smooth surfaces.
What is Pellethane?
Pellethane® is a family of medical-grade thermoplastic polyurethane elastomers. It has superior resilience, low temperature properties and exceptionally smooth surfaces.
Thermoplastic elastomers (TPE) have the processing abilities of thermoplastics and performance like thermoset rubber, but they have greater biocompatibility than rubber.
Pellethane is one of the six medical polyurethanes we extrude regularly. You can compare it with the other grades on our polyurethane tubing page, or send us your print and we will tell you whether Pellethane is the right fit for the tube you need.
Pellethane questions, answered
What is the melting point of Pellethane?
Typical melting points for Pellethane grades on our datasheet are 360°F (182°C) to 441°F (227°C). Its glass transition temperature is -40°F (-40°C) to 57.9°F (14.4°C).
What is the tensile strength of Pellethane?
Tensile strength at break for Pellethane runs 4,200 psi (28.9 MPa) to 6,500 psi (44.8 MPa), with elongation at break of 380% to 650%.
What is the density of Pellethane?
Pellethane has a specific gravity of 0.0405 lb./in.3 (1.12 g/cc) to 0.437 lb./in.3 (1.21 g/cc), which corresponds to a density of about 1.12 to 1.21 g/cm³.
How hard is Pellethane?
On our datasheet, Pellethane grades measure Shore A 77 to 94 and Shore D 49 to 80.
How can Pellethane tubing be sterilized?
Depending on grade, Pellethane is compatible with dry heat, ethylene oxide (EtO) and gamma radiation. Confirm the method for your specific grade with the resin supplier.
Does MicroSpec extrude Pellethane tubing?
Yes. We extrude Pellethane into custom medical tubing, including multi-lumen, bump and co-extruded designs. Send us your print or call 603.924.4300 for a quote.
